Description Push-button for switching on, setting the volume, aspirat- ing, and dispensing. (Button is color coded with the vol- ume range printed on the top.) Thumbwheel, to set and lock the volume. Tip-ejector button, can be positioned for left or right-handed operation.
Autoclaving The upper and lower parts of the shaft, and the tip ejector (also the tip ejector extensions for Pipetman Ultra models U-2 & U-10), are autoclavable: 121°C, 1 bar, 15–20 minutes. Operating Ranges Model Range Color Code 0.1 - 2 µL Orange U-10 0.5 - 10 µL...
6) Cycle counters: You will see the counters at the right-hand side of an otherwise blank screen. a) Since the last volume setting - holding down the push- button for 7 seconds displays this information (maximum 199); for example 126 cycles. b) Since the pipette was made - holding down the push- button for 10 seconds displays this information (maximum...
Use RAININ aerosol-resistant tips to avoid any sample-to-sam- ple, sample-to-pipette, or sample-to-operator contamination. Pipetting 1) Mount a tip: Push the shaft into a new RAININ tip using a slight twisting motion to ensure a firm and airtight seal. 2) Pre-rinse the tip: Some liquids (e.g. protein-containing solutions and organic solvents) can leave a film of liquid on the inside wall of the tip;...
3) Aspirate. Press the push-button to the first stop (this corre- sponds to the set volume of liquid). Hold the pipette vertically and immerse the tip in the liquid (see table for immersion depth). TOP POSITION Release the push-button slowly and smoothly (to top position) to aspirate the set volume of liquid.
Prevent liquids from being drawn into the Pipetman Ultra shaft by taking the following precautions: - Use RAININ aerosol-resistant tips, with an internal filter which acts as a barrier to aerosols and liquids. - Never invert or lay Pipetman Ultra down if liquid is in the tip.
6. Remove the tip from the receiving vessel without blowing out the remaining liquid. 7. Return excess sample in the tip to the original sample con- tainer, if desired. Discard the used tip. Pipetting Liquids of Varying Density Pipetman Ultra lets you compensate for solutions of density much different from water, by setting the volume slightly higher or lower than that required.
Personalizing your Pipette Tip ejector Before you start to pipette you can adjust the tip-ejector button according to your preferences. 1) Position the tip-ejector button. Simply rotate the tip-ejector button to the most comfortable position: left, right, or middle. TIP EJECTOR BUTTON TIP EJECTOR BUTTON (set for right-handed user) The tip ejector is adjustable in height to...
Tip-ejector Extension For use with Pipetman Ultra U-2 and U-10 In order to eject micro-volume tips, tip-ejector extensions are sup- plied with U-2 and U-10 pipettes. They may be already fitted to the shaft on your U-2 or U-10 model, but if they are not fitted, fol- low the instructions below.
Troubleshooting You may be able to identify and to correct the problem by referring to the following table. Symptom Possible Cause Refer to page Pipette is leaking sample Worn O-ring Pipette won’t aspirate Worn O-ring Unscrewed lower part of shaft Damaged or corroded piston 13-15 Damaged shaft...
Error Messages Contact RAININ at 800-543-4030 if you see any of these error messages on the display: Message Cause ERR1 Battery changed when the pipette was in the UNLOCKED position. Volume not set to the correct calibration volume when the calibration tool was plugged in (see "Recalibration").

2) Gently rotate the tip ejector counterclockwise and separate its connector from the activating rod. 3) Pull the tip ejector away from the body of the pipette. 4) Clean or autoclave the tip ejector and refit it (or a new one) by reversing the procedure.

Changing the o-ring The o-ring is contained by the two halves of the shaft; it must not be autoclaved, if worn or damaged in any way, it must be replaced. To access the o-ring, remove the tip ejector and unscrew the lower part of the shaft - if the o-ring is not immediately visible on the piston, set the pipette to its maximum volume, then press the push-button to the second stop.

SHAFT (LOWER) SHAFT (UPPER) SHAFT COUPLING PISTON PISTON SPRING (TAPERED) SPRING HOLDER GUIDE For U-5000 and U-10ML the shaft coupling and the upper part of the shaft are combined (see "Spare Parts"). 5) Clean and autoclave (if required) the piston and holder, together with any other parts that may need to be treated in the same way (see "Cleaning and Decontamination").

How to Lubricate the Piston (except U-2 and U-10) Use the proper lubricant (Cat. No. 70902, supplied). Squeeze a small quantity from the tube onto a clean, nonabrasive cloth. Use the cloth to transfer the lubricant to the piston. Ensure that the pis- ton is evenly lubricated, and that you wipe away any excess - only a fine film of lubricant is required (over the entire piston).
Cleaning and Decontamination Pipetman Ultra is designed so that the parts normally in contact with liquid contaminants can easily be cleaned and decontami- nated. Liquid must not enter the body (handle) of the pipette. If you use chemical solutions for decontamination or detergents for cleaning, other than specified below, you should check with your supplier that the solution or detergent used does not attack any of the following materials: stainless steel, POM (Poly-...

Decontamination Autoclaving The body (handle) of the pipette is not autoclavable. Only the following parts may be autoclaved: tip ejector, shaft (both parts), shaft coupling, piston (including holder), return spring and spring guide. The O-ring is not autoclavable; it should be replaced as specified in "Spare Parts".
