FlexCycler2 is designed for continuous use, low energy consumption, and continuity of block temperature uniformity, and is housed in a compact, ergonomic design. A peltier heating element maintains temperature control.

Quick-X-Change Block Exchange System
Exchange block modules quickly and without tools; the Quick-X-Change system automatically detects new blocks in seconds. Blocks are made of aluminum alloy for high energy efficiency.

Both single- and twin-block modules are available; twin-block modules have independent control of each side, allowing two different protocols to run simultaneously.
Gradient-function-enabled blocks (Block 96G and Block 48G) are available for quick and easy optimization of new PCR assays.

See the FlexCycler2 Block Modules Specifications for more information about the available blocks.

High Performance Smart Lid (HPSL) Heated Lid
High Performance Smart Lid (HPSL) technology ensures the formation of a homogenous tempered air cushion between the samples, excellent temperature uniformity over the entire block, and reproducible PCR conditions regardless of sample positioning.

Height and pressure are adjustable; evaporation and condensation are prevented by even distribution of pressure and optimal temperature transition between the block and reaction mix.

The large display on the Flexcycler 2 makes it easy to program in graphical or spreadsheet (tabular) program modes.
Easily toggle between tabular (top) or graphical (bottom) program modes on the large LCD display (shown with gradient display for Twin 48G block).

rPCRsoft Software and User Interface
The easy and intuitive software offers a user-specific choice of operating language and a program preview. A quick start option provides a list of the five most recently-used programs by user, eliminating the need to search through protocols. Other features include a multi-block start-and-stop function and variable heating and cooling rates. Run-log files summarize important information and help control and monitor PCR runs.

The display allows the user to toggle between tabular or graphical program modes and easily edit the parameters with the touch of a button. A total of 350 programs can be saved in 30 user directories with an option for PIN-protection.

The extended self-test allows the FlexCycler2 to test itself, summarize the test results, and alert the user if the test failed. FlexCycler2 can also create service info files for remote diagnosis.

USB Functions
Easily transfer temperature programs between FlexCycler2 instruments, store programs, save servicing records or GLP-compliant documentation of PCR runs, and perform software updates using the FlexCycler2’s two USB ports (USB A and USB B).
