Thermal Cyclers: MJ Research: PTC-200, DNA Engine
Peltier Thermal Cycler (PTC-200)
The DNA Engine instrument is the cycler that revolutionized thermal cycling. Unprecedented thermal uniformity and swappable blocks ensure consistent results, experiment-to-experiment and block-to-block. This rugged machine is more than just a cycler, it's a platform for new features and upgrades as research needs evolve.
Features of the DNA Engine thermal cycler
Single-bay cycler accommodates over ten different Alpha™ sample blocks, including independently controlled dual blocks.
Temperature Gradient capability employs dynamic ramping, guaranteeing consistent hold times across all sample wells.
Upgradable to real-time fluorescence detection with the purchase of an Opticon™ or Opticon 2 retrofit.
Advantages of all DNA Engine® systems:
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 Capability is 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.
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
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.
Manual Hot Bonnet® heated lid with a unique thumbwheel for adjusting height and pressure
Moto Alpha™ units can be remotely commanded to open, close, and adjust height and pressure. Alternatively it may be opened and closed with the touch of a button.
