Heating Blocks A laboratory Heating Block warms, cools, or maintains the temperature of samples. Different blocks can be placed into the heated base to adjust to various sizes of sample containers. “Heating/cooling blocks are ideal for warming up or cooling down samples in labs that have limited space. Perhaps there is not enough room for a bath or the lab tech is afraid something will fall into a bath,” said Anthony Murphy, Application Specialist. “Users simply dial in the temperature on the heating block and it remains constant.” The blocks are best used with smaller samples in plates, vials or tubes. They are typically found in microbiology and life science research. Specifics to consider when needing to keep samples at the right temperature How much power or capacity is necessary for your application? What total volume are you using? What kind of container are samples in? What temperature range is needed? What is the delta or the change in temperature anticipated? How much temperature control do you want for your solution? Are you circulating externally? What fluid are you typically using?
