Vacuum Free Cryostats for UV-VIS, Fluorescence and Circular Dichroism: USP-203 Series

USP-203 Series of products are stand-alone cryostats. Their light weight and compact footprint allows them to be placed inside most commercial UV-VIS, Fluorescence and CD Spectrometers with proper adaptation. This allows temperature controlled measurements of absorption, fluorescence, or circular dichroism spectra.

The USP-203 Series of products have been used to measure liquid, solid or powder samples.

  • UV-VIS-NIR absorption spectra
  • Transient Absorption spectra and decays
  • Circular Dichroism spectra
  • Photoluminescence/ Fluorescence/ Phosphorescence spectra in UV- VIS- NIR
  • Photoluminescence decays

Outstanding Features

  • Vacuum Free–the cryostat does not require vacuum pumps to operate! No Waiting in the noise of the vacuum pump before starting your experiments.
  • Liquid Sample–no worries! It uses Standard Quartz 10cm x 10cm cuvette!
  • Kinetic Study–great! Reagents can be injected and mixed by the magnetic stirrer, makes it easy for kinetic measurements!
  • Small Volume of samples: adaptor available to accommodate 1mm optical path cuvette!
  • Both Cooling (-80 °C standard, -180 °C conditional) and Heating (+100 °C).
  • Light weight and compact footprint.
