Primary Laboratory Large Quartz Fixed Point Cells
These cells meet all the requirements of science and industry for Fixed Point Realizations of ITS-90.

• 99.99995% purity

• ITS-90 Fixed Points

• Sealed or Open Models

The cells now offered have been increased in purity and length to conform to the requirements of optimal realizations except that we have sealed in 1 atmosphere of 6N pure argon at the freeze temperature for you. Sealed optimal realizations of ITS-90 are made from metal exceeding 6N5 purity and have a useable depth below the metal surface of more than 200mm. They come complete with Inconel basket, a carry case and the necessary heat shunts and reflectors to enable them to fit into our apparatus.
