A dry bath is a type of laboratory equipment that is used to heat samples. Dry baths are often used in molecular biology, microbiology, biochemistry and genetic applications. The capacity of these baths is measured in blocks. Depending on the size of the block, the user can place a certain amount of tubes into each block. The most common sizes for blocks are 1, 2 and 4 block models.
There are two main types of dry baths including digital dry bath and analog dry baths. Digital dry baths incorporate a microchip into the model which allows the temperature of the bath to be controlled through the digital interface while analog dry baths do not use microchip technology.
