  • Page 7: Introduction

    A. INTRODUCTION The Thermo Scientific Matrix Electronic Pipette provides the convenience of a manual pipettor, with the programming capabilities of an electronic pipette. The Matrix electronic pipette features include: • Expanded memory for storing up to five pipetting programs. • Each program can hold a maximum of 40 steps. • “Scratch Pad” programming mode which allows for fast and simple program changes that are not stored into memory. • Enhanced speed control offers slower aspirating and dispensing of viscous liquids. Ideal for gel loading! • “EASY” CAL which simplifies in-lab calibration verification using distilled water. The Matrix electronic pipette is lightweight and cordless, utilizing rechargeable batteries, that can be used during recharge (with the exception of single channel pipettes). The pipette also has an automatic shut-off feature to extend battery life. The electronic pipette uses integrated circuit technology to store programming information. It will hold up to 40 steps in a program, with up to 5 programs saved in memory, and 1 scratch pad (See section C.1.1 Open Programming Mode or “Scratch Pad”). The program information is retained in memory even if the batteries are fully discharged or removed. The electronic pipette uses a “paced dispense” feature that performs repeat pipetting steps while the trigger is depressed.

The display is an LCD screen that shows the pipetting operation (fill, dispense, mix, or purge) and fluid volume for each step in the pipetting program. (See Section B.4, Display). Battery Case. The battery case contains the rechargeable batteries. Nickel Metal Hydride batteries fully charge in 14-16 hours, while Lithium-Ion batteries fully charge in 2 hours. The pipette can perform a full day’s workload with no need to recharge. Battery life is extended with automatic shut-off after 10 minutes of inactivity. (See Section F.3, Installing/Replacing Batteries). Pipetting Trigger. The pipetting trigger initiates a program. A single pipetting step is executed by a quick press and release of the trigger. Repeat pipetting is executed by pressing and holding the trigger. Note: At the end of any dispense, the pipette tips should be removed from the fluid before releasing the trigger, to prevent aspiration of fluid.

  • Page 11: Keypad

    Pipette Overview B.3 Keypad The keypad contains the operation keys, programming keys, and the special function key. Figure B.3: Electronic Pipette Keypad B.3.1 Operation Keys [On/Off] The On/Off key turns the pipette on or off. When the pipette is turned on, it emits a beep tone, flashes “ZERO” on the display, then automatically resets the pistons to zero position. After zeroing, the display shows the first step of the program in the RUN mode. Note: If the pipette is being programmed for the first time, the first step will be the fill operation, with the default fill volume. (See Section C.1, Programming the pipette, for the default settings).

  • Page 12: Programming Keys

    Pipette Overview [Purge] The Purge key enters a purge prompt anytime during a pipetting operation to abort the program. By pressing the Purge key, then pressing the trigger, you can dispense any remaining liquid from the pipette tips and return to the beginning of the program. The Purge key is also used to enter the purge step into a program. Note: If there is insufficient liquid for a final dispense step, the pipette emits a beep tone and automatically displays the purge prompt. Note: The RUN mode performs the operation that is displayed, such as fill, dispense, mix, or purge.

  • Page 13: Special Function Key

    Pipette Overview Note: If you press and hold in the trigger during the final dispense step, the pipette performs the automatic blowout and holds its position until you release the trigger. This delay allows you sufficient time to remove the tips from the liquid to prevent aspiration of liquid as the pistons return to zero position. The Volume key controls the quantity of liquid to be aspirated or dispensed. The volume can be entered when the “Vol” prompt appears. Pipetting volume can be incremented quickly by continuously depressing the Volume key. The longer you hold the key, the greater the incremental speed. The Volume key can also be used to change pipetting speeds within a stored program or during the execution of a program. (See Section C.1.5, Adjusting Pipetting Speed). [Enter] The Enter key stores the program in memory. After each step is programmed, the Enter key is pressed once to accept the step. After the final step is programmed, the Enter key is pressed twice to denote the end of the program. The pipette verifies the end of the program with a triple beep tone. B.3.3 Special Function Key The Special Function key is the small hole below the Volume key. It can be activated with a pipette tip. By repeatedly pressing the Special Function key, you can display four functions: Pipetting Speed (SPd), Beep Tone (TONE), Paced Dispense Speed (PACE), and Calibration (CAL). To exit the Special Function key at any time, press the Enter key.
  • Page 14 Pipette Overview Pipetting speed can be adjusted by pressing the Volume key in the special function mode. Five speed settings are available: Speed Setting Display Slow Medium Slow Medium Medium Fast Fast TONE The beep tone signals the completion of one or more steps, or signals a warning: • Single beep tone: end of pipetting step. • Double beep tone: operation or programming key is not active in current mode; insufficient dispense volume, purge required; or illegal programming step attempted (see Section E, Troubleshooting). • Triple beep tone: end of pipetting sequence; end of programming sequence. There are three options to choose from in setting the beep tone. ON1 sounds all tones at the appropriate times listed above. ON2 uses only double and triple beep tones. OFF turns off all tones except for the tone to signify an illegal programming step. Press the Special Function key twice to display “TONE” and its current setting. To change the setting, press the Volume key. If the beep tone is set for ON1 or ON2, the beep tone symbol “ ” appears at the bottom of the display.

  • Page 18: Programming And Operation

    Programming and Operation C. PROGRAMMING AND OPERATION C.1 Programming the Electronic Pipette gramming the Matrix electronic pipette is fast and easy. Pipetting steps and volume are entered in the sequence that they will be performed, then the program is saved to memory. This program will stay in memory (even if the pipette is turned off, or the electronic pipette battery runs low) until you change it. Five programs and one scratch pad (Program 0), each capable of holding 40 steps, can be entered and stored in the electronic pipette. C.1.1 Open Programming Mode or “Scratch Pad” (Program 0) The Matrix electronic pipette provides ample program storage for five, 40-step programs. In addition, it offers open programming mode, also known as the “scratch pad.” This mode is identified by “P-0,” which appears in the program section of the display (refer to the pipette display on page 10). This feature enables quick changes to pipetting protocols without affecting previously stored programs. To use the “scratch pad” mode: From the start of any program, simply begin entering a new protocol (selecting a pipetting operation as described below). This new protocol can now be used, and will remain active until a stored program is retrieved. “P-0” appears in...

  • Page 20 Programming and Operation Mix. The [Mix] key programs the pipette to perform a combination of fills and dispenses. You can program a mix volume or mix cycle (single fill and dispense). You can press [Mix] once to program a mix volume, or twice to program a mix cycle. Mix cycles from 2 to 9 are available on the pipette. The default setting is three mix cycles. Some programming considerations for the mix operation: • If the program begins a mix cycle from zero position, it will complete the cycle with an automatic blowout, then display “ZERO.” Press the trigger to return the pistons to zero position. • If the program begins a mix cycle above zero position (volume is greater than zero), the fluid is dispensed, and the mix cycle begins. The mix cycle will end at the same volume it started with. Also, the mix operation will remain in the display so it can be repeated (useful for serial dilutions), unless followed by another program step. To end the mix operation, press the [Purge] key, then press the trigger. Purge. The [Purge] key programs the pipette to purge the fluid. This step can be entered as a program step, or it can be pressed any time while pipetting to terminate the program and dispense the remaining liquid. Note: If the program ends at a volume greater than zero, and the last step is not a mix cycle, the “Purge” prompt automatically appears. Also, the pipette emits a double beep tone to warn you that some fluid remains.

C.1.4 Program Recall To recall a stored program: 1. Press the [Prog] key, then the [Vol] key to select the desired program number. 2. Press the [Enter] key to activate the displayed program. C.1.5 Adjusting Pipetting Speed The Matrix electronic pipette offers unique speed control programming for Fill, Dispense, Mix, or Purge. Speeds within any of the five stored programs can be independently set and stored as an integral part of the pipetting protocol. Pipetting speed is easily changed at the start of each pipetting function. To change pipetting speed during the execution of a program: Press the [Vol] key to select the speed for each pipetting step (Fill, Dispense, or Mix only). If purge is programmed as a step, its speed can also be programmed. Note: Purge must be changed in the program. This newly set speed will remain active with each function even if the pipette is turned off. Speed settings within any of the five stored programs will also remain in memory with the program functions until changed by the operator. C.1.6 Reviewing the Program After programming the pipette, review the programming steps: 1.

  • Page 23: Programming Examples

    Programming and Operation 3. Observe display. At each step of the program, observe the display. If necessary, re-enter the programming sequence. Some helpful hints for reviewing your program: • If the program is complex and contains several steps, write the steps on paper before entering the program. Check off each step as you review the program. • If the program is intended for paced dispensing, review the program again, with the trigger depressed until the last step. Check the dispense pace to ensure the dispense steps are a comfortable speed. C.2 Programming Examples Examples of different pipetting sequences are described below, and are ideal for use as training exercises. Press the keys shown in brackets [ ], then press the [Vol] key until the volume in parentheses ( ) is displayed. At the end of the program, a triple beep tone is sounded.

  • Page 28: Calibration

    Calibration D. CALIBRATION Each electronic pipette is factory-calibrated for distilled water at 20 °C. For easy calibration using distilled water, the pipette features an “EASY” CAL mode (see Section D.2.2, “EASY” CAL mode). When pipetting liquids of significantly different specific gravities or temperatures, however, the Calibration (CALC) feature may be used to achieve greater accuracy (see Section D.2.3, “CALC” mode). To prepare for calibration, ensure the pipette and tips are equilibrated. When calibrating a multichannel pipette, select only one channel to pipette with. Using an analytical balance, first obtain the actual value of the programmed volume at factory calibration. The programmed volume (Vp) used is typically the calibration point for that pipette (Refer to Table D.2.2) D.1 Volume Measurement To measure the actual value of the programmed volume: Fill the programmed volume (Vp), then dispense the entire volume into a container on the analytical balance. 2. Read the weight on the analytical balance. Repeat this procedure ten times. ote: Use a clean and dry pipette tip with each pipetting cycle. When filling the liquid, immerse the pipette tip approximately 1/4 inch (approx. 0.6 cm) below the liquid surface.

  • Page 29: Pipette Calibration

    Calibration D.2 Calibration Electronic pipette users can calibrate their pipettes with “EASY” CAL mode for distilled water or with “CALC” mode to calibrate other liquids and for temperatures other than room temperature. D.2.1 Factory Calibration Step The factory calibration step is needed when calibrating your electronic pipette. This is located on the calibration certificate called “Pipette Calibration Report” enclosed in the documention for this pipette. (See comments on page 1 of Pipette Calibration Report). View the pipette’s current calibration step by using the CALVIEW mode listed in section D.2.4. Note: When resetting the calibration step to a default value, as listed in section D.2.5 CALRESET, the step is set to an average value for all pipettes of its class. This value may differ from the factory-optimized calibration step documented on the “Pipette Calibration Report”...

  • Page 30: Calc" Mode

    Calibration 1. Weigh out ten aliquots of distilled water on an analytical balance using one pipetting channel. The programmed dispense volume must correspond to the calibration point for that pipette (for example, 200 µl for a 250 µl pipette). Refer to Table D.2.2, Calibration Specifications, for proper calibration points. Note: Ensure that the distilled water used is at room temperature (20-22.5 °C). An internal correction factor of 1.003 is used by the pipette to convert weight (gm) to volume (ml).

    Calibration D.2.4 CALVIEW CALVIEW displays the pipetting stroke (number of motor steps) used to reach the calibration point. This value allows you to confirm the calibration during pipetting and after calibration. To activate CALVIEW, enter the CAL mode using the Special Function key. When the calibration point is displayed, exit press the [Fill] key. The number of steps is displayed. Press any key to CALVIEW. D.2.5 CALRESET CALRESET allows you to return to a default calibration step. To reset the calibration, enter the CAL mode using the Special Function key. When the calibration point is displayed, press the [Purge] key. The display flashes “FACT,” “CAL,” then “SET” and the pipette resets to the default step. This default setting is an average value for all pipettes of its class. This value may differ from the factory-optimized calibration step documented on the “Pipette Calibration Report” certificate enclosed in this pipette’s documentation. D.3 Recommendations for Accurate Pipetting Matrix Electronic pipettes are factory calibrated to deliver accurate volumes with distilled water at 21 °C and 50% humidity. By using the calibration procedures described above, you can pipette liquids of different specific...
  • Page 33 Calibration • Calibrate the pipette for the liquid. If the liquid has a specific gravity and vapor pressure equivalent to distilled water, calibrate using “EASY” CAL mode. Otherwise, use “CALC” mode. • Pre-wet the pipette tip. Aspirate and dispense a few times before aspirating the liquid to increase humidity within the tip, reducing sample evaporation that results in lower dispense volumes in initial few pipettings. The need to pre-wet increases when working with liquids with high vapor pressure and/or high surface tension. • Immerse tips fully. Tips should be immersed approximately 1/4 inch (approx. 0.6 cm) below the liquids meniscus and away from the container surfaces to avoid aspiration of air and excess droplets clinging to the outside of the tip. • Discard a primer volume. When the motor changes from aspiration to dispense, the percentage of error is greater in the first dispense than in subsequent dispenses. • Pause consistently. It takes a moment for the liquid in the tip to finish moving. Pause with the tip in the liquid for about one second after aspirating the sample to allow the liquid to finish moviing into the pipette tip after the pipette stops. Otherwise, the volume will be lower than it should.

Fit the edges of the pipette top snugly within the edges along the top of the pipette housing. F.4 Charging/Recharging Batteries F.4.1 Charging/Recharging Nickel Metal Hydride (NiMH) Batteries The electronic pipette uses two Nickel Metal Hydride (NiMH) rechargeable batteries, located in a battery case under the keypad. The batteries are charged in the pipette by using the power transformer included in the package, with the exception of single channel pipettes which do not have this ability. You can operate the pipette while it is recharging, or you can operate it solely with the power transformer (without batteries). The batteries can be recharged approximately 400-500 times. To extend battery life, the pipette will turn off automatically if it is not used within ten minutes. 1. Attach transformer. Attach the cable end of the transformer into the pipette. Plug the transformer into the electrical outlet. 2. Recharge batteries. Recharge batteries for 14-16 hours to ensure a full charge. After the batteries have been recharged, unplug the pipette from the transformer. Note: Batteries hold their maximum charge if they are fully discharged before recharging again.

    Maintenance CAUTION! Avoid excessive charging of the batteries when the pipette is not in use. Excessive charge to the batteries will shorten the battery life and may damage the batteries. F.4.2 Charging/Recharging Lithium-Ion Battery (16 Channel Electronic Pipette) The 16 channel electronic pipette uses a Lithium-Ion rechargeable battery located in a battery case under the keypad. The battery is charged while it is in the pipette by using the power transformer included in the package. The pipettor can be operated while it is recharging. The battery can be recharged approximately 400-500 times. To extend battery life, the pipette will turn off automatically if it is not used within ten minutes. Rapid Charge - The battery should be charged for 1.5 to 2 hours to achieve a full charge. Refer to the following table for partial charge times: Amount of Charge Time 1.25 hour 1.5 hours 100% 2 hours max The battery pack for the 16 channel Electronic pipette features an indicator light to indicate the state of charge of the battery while plugged into the power supply. With the unit plugged in, the indicator operates as follows: • Green - Indicates that the power supply is connected. •...
  • Page 57 Maintenance As the unit continues to charge, current is supplied in pulses. This is indicated by the flashing of the indicator. As the battery nears full charge, the flashing slows down becoming nearly a constant green. When the battery is fully charged, the indicator will be almost a constant green, flashing only about once every 3-5 seconds to ensure the battery stays fully charged. Note: The typical life expectancy of the battery is approximately 400-500 full recharges. To prolong this and attain the maximum usage from the battery, it is recommended the battery be recharged whenever it is not being used instead of waiting until the battery is completely discharged.
