The dry bath incubator with heat block are a popular choice in many labs today. A small amount of used space and dependability are some of the qualities that make them the first choice. The dry bath incubator easily sits directly at the work bench where testing is performed. They may be used for various test such as AHG cross match and antibody ID’s. Blocks of various diameters may chosen to accommodate different testing modalities. Temperature consistency is another common factor for heat blocks. The temperature range is usually within 2 centigrade. The temperature in the wells of the heat block are uniform. Some organizations still require a thermometer that is rotated each day in each well.
