Cryostat For Spectrophotometer

A cryostat to be placed inside a sample compartment of commercially available spectrophotometers. It enables you to obtain absorption, fluorescence, or circular dichroism spectral information on a sample solution under low-temperature condition. Measurements in a temperature range from -80°C to +100°C is realized by using liquid nitrogen as a coolant.
