MJ Research DNA Engine TETRAD2

The MJ Research PTC-240 DNA Engine Tetrad 2 thermal cycler is a completely redesigned
and updated version of the original Tetrad chassis, and it accepts the full line
of well-proven Alpha™ heat-pump assemblies.
It delivers the same precision in thermal performance as the DNA Engine Dyad®,
and original Tetrad thermal cyclers, allowing easy transport of protocols among platforms.

The Tetrad 2 contains an onboard Pentium®-class computer that delivers an advanced
graphical interface—ideal for managing production-grade thermal cycling.
For those labs that value quick training, the creation and editing of protocols
can be accomplished rapidly and easily via the mouse-directed “point-and-click” navigation.
Real-time displays of block, sample and lid temperatures provide quality assurance
that the thermal cycler is performing as directed. Superior software features, such as error tracking logs,
run tracking files, problem resolution trees and file management tools, offer invaluable information for troubleshooting during high throughput runs.

Features of the DNA Engine Tetrad 2 Peltier Thermal cycler:
4-bay high-throughput thermal cycling
Up to 8 individual sample blocks, which can be controlled independently or as a group
Up to 1536 samples can be processed simultaneously
Internal power supply—no separate “boxes” to accommodate
High-density color display and on-board mousepad, with point-and-click navigation of software
Real-time monitoring of cycling temperatures

Advantages of all DNA Engine systems:
Sample Blocks:
Swappable Alpha unit sample blocks are designed for frequent change; they can be swapped in seconds; they seat many types of reaction vessels.
Independently controlled dual blocks are available for running two different protocols simultaneously.
Gradient capabilities standard on all DNA Engine systems when fitted with 96-well Alpha units.
Unique Peltier heat pumps are built by MJ Research specifically for cycling. Years of experience and proprietary technologies make MJ modules last longer than any other.
Multi-zone feedback control utilizes multiple sensors combined with four “zones” for heating and/or cooling to optimize thermal profiles every 50 milliseconds.

Performance:
Extraordinary temperature uniformity of ±0.4°C within 30 seconds of arrival at 90°C (well-to-well) average, all Alphas.
Superb thermal accuracy of blocks within ±0.3°C of NIST standard at 90°C (average across block, all Alphas).
Thermal range of -5° to 105°C
Rapid ramp rates of up to 3.0°C/sec

Operation:
Two thermal control options block control or calculated control.
Choice of two heated-lid designs accommodate many vessel types and various sealing options,
allowing maximum flexibility in experimental designs.
Heated lid temperatures can be set with any DNA Engine instrument.
