SuperTran-VP Continuous Flow Cryostat Systems - Sample in Vapor

Janis

STVP-100 Optical Cryostat Systems

Optical continuous flow cryostats with three standard sizes available, although as with all Janis systems these systems can be customized to suit your experiment. Systems with a 1.5" sample space are in stock for fast delivery.

STVP-100-FTIR Cryostat Systems

Optical continuous flow cryostats for FTIR applications. These cryostats are similar to our standard model STVP-100 cryostats, but with the modifications for integrating the cryostat with your spectrometer system.

STVP-200 Non-optical Cryostat Systems

Continuous flow cryostats with tubular tails for non-optical experiments, with a range of sizes available.

STVP-200-NMR Non-optical Cryostat Systems

Similar to the standard STVP-200 Tubular System, but custom designed for NMR Spectroscopy.
