Cryostats for FTIR Applications

Liquid Nitrogen Pourfill Cryostat
Model VPF-100-FTIR

A special liquid nitrogen pourfill cryostat (VPF-100), the VPF-100-FTIR includes a multiple position sample holder and a linear manipulator for studying several samples without warming the cryostat.

As with all of the FTIR cryostats, the window material may be user-specified and many details of the design may be altered to suit your requirements. Contact Janis today to find out how.  Click here for an example of a modified system.
