Slim Fixed Point Cells

• Affordable - Models for ISOCAL-6 Range
• High Accuracy
• 99.9999% Purity Metals (6N)

Isotech’s 6N Quality Quartz Clad Slim Cells have been in constant use for more than ten years and have a proven record of successful use in many laboratories World-wide.

The Cells themselves are made from the highest quality graphite and quartz glass and are sealed with 1 atmosphere of 6N (99.9999%) pure argon at the freeze temperature. The metals are also 6N purity to ensure the most accurate realisation of ITS-90.Isotech’s Slim Fixed Point Cells can be used to calibrate temperature sensors, either as the metal within them melts, or as it freezes.
Typically, says CCT/96-8, a 6N pure cell will melt over 80% of its plateau within ±1mK. Exceptionally Isotech’s Gallium Cell will melt over ±0.2mK.

The purpose of Slim Cells is to calibrate shorter sensors, and so large apparatus is inappropriate.
