VNF-100

September 2000

Janis Research Company is now offering a liquid nitrogen variable temperature cryostat with the sample located in flowing vapor.  Ideal for experiments with samples that are difficult to thermally anchor, such as liquid or powder samples, the VNF-100 is a low-cost alternative to the SuperTran-VP or SuperVariTemp dewars when temperatures below 60 K are not required.

The VNF-100 features a top-loading sample chamber for rapid sample exchange, and four-way, ƒ = 1.0 optical access to the sample chamber.  Options include special window materials to facilitate spectroscopy in any range of the electromagnetic spectrum, special sample holders (including cuvette holders), and feedthrough ports to which a variety of hermetically sealed electrical feedthroughs may be mounted.  Tubular-tailed designs are also available for use in non-optical applications.  The VNF-100 can even be adapted to fit your spectrometer.

As with all Janis products, variations on the standard design are available in order to adapt the VNF-100 to your specific experimental requirements.
