Hot warning light indicates when the block temperature is above 50°C
Dry block heaters are designed for precise heating of test tubes, microcentrifuge tubes, cuvettes, and microtiter plates. The large thermal mass of the aluminum blocks provides very accurate and stable temperature control. The “number of blocks accepted” indicates the number of single-width blocks accepted by each heater. A heater that accepts two single-width blocks will also accept one double-width block.
