Dry Block Heaters
Dry block heaters are laboratory instruments designed to provide controlled and uniform heating for the incubation, denaturation, or activation of samples in tubes or microplates. They consist of a block with wells or slots to hold the sample vessels, and a heating element to raise the temperature of the block. The term "dry" refers to the fact that these heaters do not use water or other liquids for temperature control; instead, they rely on direct contact between the sample vessels and the heated block.
Here are some key features and applications of dry block heaters:
-
Temperature Control:
- Dry block heaters typically have a digital temperature control system that allows users to set and maintain a specific temperature. The temperature control is crucial for various biological and chemical applications that require precise and stable conditions.
