Dry Bath

Dry bath is a very useful device in histology, clinical, environmental, molecular biology and industrial laboratories. Dry baths are like heated chambers filled with salt, sand or aluminum blocks designed in such a way to hold different sizes of glassware. Now-a-days digital dry baths are becoming largely popular. They are ideal for inactivation of sera, enzyme reactions, blood cross-matching, cholesterol determinations and Rh studies.

Dry baths are good alternatives to hot plates. They are substituting water baths in many laboratories. Dry baths are found in analog as well as digital models. They are controlled by microprocessors that regulates the high power heaters in the baths and provide accurate temperature control. It avoids any checking of temperature through thermometer and any need of readjusting temp.

The block portion of a dry bath should be made of material, which is able to transfer the heat uniformly from the heating elements to the interchangeable blocks. The block should be of uniform size so that all of them receive equal temperature treatment irrespective of their position in the block.
