Px2 THERMAL CYCLER Introduction 1.1 Overview Px2 is the essence of fast, accurate licensed thermal cycling. Px2 features high capacity, high speed and sub-ambient blocks to perform oil-free thermal cycling with excellent dynamic uniformity and precision control of sample temperature.
(1mm thick). Heating and Cooling The Px2 sub-ambient blocks are built to proven designs, providing an accurate and reliable thermal cycling system. The sub-ambient aluminium block is heated and cooled by the latest in Peltier technology. With proven durability, the block modules excel in performing applications such as RAPDs and Differential Display, which require cycling temperatures close to ambient.
The Px2 can thus be programmed to perform all types of temperature controlled reactions, from simple one step incubations, to complex multi-step temperature cycling protocols and temperature gradient experiments*.
Advanced Edit – Gradient (optional) For rapid optimisation of primer annealing parameters the Px2 gradient feature should be used. A maximum temperature gradient of 15°C can be programmed across the 96 well block. Calibration of your Px2 Every machine is calibrated using miniature thermistor probes located in tubes or attached to microscope slides.

2. Before use, ensure that the unit has been set to the appropriate mains voltage. 3. The Px2 is a class 1 appliance. To minimise the risk of electric shock, the unit must be connected to a protective earth via the supplied mains cord.
2.2 Symbols & Conventions The Px2 has been designed for safe operation. The following symbols appear on the unit and their meanings should be noted. Indicates the ON position of the main power switch. Indicates the OFF position of the main power switch.
RS232 Lead NB: The In Situ Flat Block Module includes a humidity chamber. If any item is missing or damaged, contact the UK Service Department, or your local Thermo Hybaid office/authorised distributor. Ensure any padding between the plate inside the heated lid and the block is removed before using the instrument.
In Px2 systems, excess heat is removed from the system by a fan. The air intake for the fan is located underneath the unit and air is expelled out of the back of the unit. To ensure correct airflow around the unit, allow at least 8cm clearance between the sides of each module and 15cm of clearance at the back of the unit.
Figure 3.2 Well Numbering Showing Tube Thermistor Positioning in A2 Use in Cold Rooms The Px2 may be used in a cold room (down to 4°C). However, when removed to room temperature the instrument should be allowed to equilibrate for at least two hours before being switched on. If equilibration is not done, condensation may form within the unit and cause a short circuit.
Operating Instructions 4.1 Initial Start Up Switch on the Px2 using the power switch at the rear of the unit. When first switched on the unit will complete a start up and self test routine. After 5 seconds a screen will display “Self-check procedure in progress”.
4.3 Operating Keys The Px2 software is designed to be intuitive; the following table gives a summary of the primary functions of each of the operating keys. Table 4.2 Function Keys FUNCTION ENTER KEY Selecting Menu and program choices. MENU KEY Always moves to the Main Menu –...
Power Failure Resume If there is a power interruption during a run, the Px2 will switch back on automatically. The unit can be set to resume a program (at the cycle and setpoint where the interruption occurred) or to abandon the program.
4.6 Running a Program Design of the Px2 software ensures that running a pre-stored protocol is easy. • At the Main Menu, select RUN by depressing the relevant softkey. • Select the source directory (e.g. F: THERMO) using the directional UP and DOWN softkeys and press ENTER.
4.8 Programming Function PCR protocols of varying degrees of complexity can easily be created using Px2. As with all operations of the Px2, programming is accessed from the Main Menu. Access the Program Menu by selecting PROG from the main menu. If at any time you wish to stop programming, press MENU to return to the Main Menu.
4.9 Loading Samples and Heated Lid Operation The Px2 will produce identical cycling profiles whether 1 or 96 samples are to be analysed. The following guidelines maximise the uniformity and thermal transfer characteristics of the block thus ensuring optimal sample to sample reproducibility: •...
Programming the Px2 5.1 Introduction The Px2 has been designed to make programming user friendly and easy. The memory will hold up to 99 complete thermal cycling protocols including 10 pre-programmed template programs (Nos. 90-99 detailed in Appendix V). Programs are identified by a number (01-99) and a user defined name (up to 7 characters).
4. A final confirmation screen allows you either KEEP or ERASE the directory. 5.3 Programs The programs in the Px2 are divided into ‘stages’ and ‘steps’ when displayed on the screen. In a simple PCR program a stage typically includes three steps where each step refers to the temperatures and times within the protocol.
Note: If there are no free program spaces the Px2 will prompt you to overwrite an existing program. 7. Enter temperature (e.g. 95°C) and time (hr:min:sec), as required. Use the LEFT softkey to move the cursor as desired or ENTER to advance to the next step. The UP softkey can be used to scroll backward to correct a mistake.

ADVANCED softkey at the relevant step (see section 5.4). It is possible to edit programs whilst the Px2 is running a different protocol. 1. To edit and overwrite existing programs select PROG from the Main Menu using the appropriate softkey.
If the combination of the Set Annealing Temperature and Gradient results in the block operating outside the temperature limits of 30 to 70 C, the Px2 alters the temperatures to remain within these limits. E.g. SET TEMP = 60 C and GRAD = 15 C.
• Choose whether to run your samples oil-free i.e. heated lid option. Once a program is selected, the program name will be displayed and lid preheating (if selected) will commence. It is possible to edit programs whilst the Px2 is running a different protocol (see Section 5.3).
This allows the user to monitor the performance of the Px2 and to determine the time of the end of the program. The second screen is the graphical display which shows the block and tube / sim tube temperatures.
• The stage in the run when the power failure occurred. End of Run Screen The Px2 displays a further screen at the end of the run, which provides the following: • The program name and number. • The total run time.
CANNOT be used with Px2 thermal cyclers. Extension Lead for the Tube Thermistor The Px2 is provided with an extension lead for the thermistor. This should only be used for transferring protocols from instruments that cannot use Active Tube Control. See Section 7.3 for further details.
6.6. Hold & Pause Function When entering a program the Px2 will give you the opportunity to enter a ‘Hold’ temperature at the end of each stage. The samples will be held at this set temperature indefinitely. The screen will display HOLD during a run.
The Px2 block accommodates most types of reaction tubes. The tube thermistor supplied with the Px2 is mounted on an OmniTube, which should be changed periodically, as the fit of the tube will deteriorate with time. Reaction tubes should be distributed evenly in the block. If you are using a reaction tube that has not been recommended, check its fit in the Px2 block before use.
1. Set the Px2 to run a single program at a set temperature for an extended time. (e.g. 37°C for 4 hrs), ensuring that the heated lid is switched off and the instrument is set to block control. This enables the tube thermistor to be used remotely.
Thermo Hybaid office or authorised dealer to check that the proposed method will not damage the equipment. All surfaces of the Px2 system and heated lid should be cleaned regularly with a soft cloth, hot water and a mild detergent.
8.4 Protection of the Instrument Fuses The Px2 mains power inlet is fitted with two T6.3A fuses (20mm x 5mm). If necessary these may be replaced by a qualified person. 8.5 Tube Thermistor Care The tube thermistor assembly ensures that the programmed temperature profile is accurately and reproducibly achieved within all sample tubes.

Typically volume loss of 3µl per well in a 30-cycle reaction can be expected. The Thermo Hybaid OmniUltra helps to address this problem to some extent. In our tests reaction volumes of 10µl gave strong results. 5µl reaction volumes gave visible but faint results thus 10µl is the minimum recommended sample volume for this plate.
In Situ Block Application Notes Overview The Px2 In Situ module with flat block has been designed for the precise control of temperature on up to four standard microscope slides (dimensions 76mm x 26mm x 1mm). Flat blocks are supplied with a Humidity Chamber, which can be used to reduce sample drying.

3°C. Programming Programming and operation of the In Situ module are identical to the standard Px2 tube modules (see Chapter 5) with the exceptions previously noted and also no heated lid operation is supported. For simple fixed temperature incubations of the slides, manual control can be used (see section 4.7). For more complex multi-step incubations or for temperature cycling reactions a protocol can be designed and run using Simulated Slide Control (see Chapter 6).
In Situ Module The Px2 Flat Block, for performing In Situ reactions on up to four microscope slides. Loading Factor To compensate for differing numbers of samples, enter the number of tubes for each cycling run.
