A high accuracy bench-top incubator to grow and maintain gametes and embryos in IVF applications – BT37

The incubator will keep cells at optimal temperature, humidity and gas content by maintaining a constant and clean environment.

It has extremely accurate  temperature control, systems for pH stability and regulated humidity.

Accuracy and control of a chamber to obtain environmental homeostasis is important in cell development. The BT 37 bench-top incubator is the most accurate of its kind, helping to ensure an embryo suffers little or no exposure to temperature or pH level changes.
