What is a dry block heater?
A dry block heater, also know as a dry bath incubator or simply dry bath, is used to heat samples in a variety of applications. The blocks are made of an aluminium alloy which allows the distribution of heat in a uniform manner. Dry block heaters are widely used in molecular biology and clinical and environmental laboratories.
Why would you use a dry block heater?
The term "dry" means that the samples are heated without a liquid bath, making it a convenient and versatile heating solution for many laboratory applications. The purpose of dry block heaters is to control the temperature so that it’s uniform, stable, and precise during heating and cooling applications. Dry block heaters generally provide excellent temperature control and uniformity. 
What are dry block heaters used for?

A dry block heater is a laboratory instrument that is used to heat a variety of samples to a set temperature for a range of applications, including but not limited to:

  1. Molecular biology: For processes such as PCR (polymerase chain reaction), where a constant temperature is required to amplify DNA.

  2. Biochemistry: For enzymes assays, protein denaturation and other chemical reactions.

  3. Materials science: For the preparation of samples prior to analysis, or for applications such as thermal analysis.

  4. Environmental testing: For the determination of the thermal stability of a sample.

Can Thermoline manufacture custom blocks?
