The MC-0203 from Major Science is a robust and compact dry block cooler and heater that uses a range of interchangeable alloy blocks for cooling and heating samples in tubes and tube strips. The MC-0203 has a moulded aluminium block chamber that ensures even heating and cooling and no leakage so that the instrument can also be used as a water bath or bead bath.

The MC-0203 features a PTFE coating for stain resistance and easy cleaning and a clear polycarbonate lid for increased temperature stability. Peltier cooling systems provide rapid cooling and the unit has a bright LCD display with a touch control panel and a timer function with audible alarm.

The MC-0203 has multiple operating modes including constant temperature (-10°C to 100°C), programmed (1-4 steps and up to 9 cycles), annealing, and quick start (4°C, 16°C, 37°C, 56°C, 95°C pre-set).

The MC-0203 is ideal for remote use as it can be powered from a vehicle using the vehicle adapter. The unit incorporates a USB port for easy data logging.

Blocks and other options

These precision-machined aluminium alloy blocks allow for highly efficient cooling and heating of samples. They have a block lifting well to assist in removing the block from the instrument and a well to allow the insertion of a thermometer. A block lifter is included with the purchase of the MC-0203.
