Cryostat For Spectrometer USP-203 / USP-203CD

This is 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.
Measurement in a temperature range from -80 deg C to +100 deg C is realized by the use of liquid nitrogen as a coolant and for ease of operation.
