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
Fixed Point Cell. Primary Standard.
| Model | Description |
|---|---|
| ITL-M-1XXXX | Fixed Point Cell. Primary Standard. |
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.
| Diameter | Typically 50mm |
| Length (sealed cell) | Typically 275mm excluding sealing tip |
| Length (open cell) | Indium, Tin, Lead, Zinc: 520mm to underneath of flange Antimony, Aluminum, Silver, Copper: 610mm to underneath of flange |
| Thermometer Immersion | Below metal surface 200mm Clients often confuse the immersion in the cell with the total immersion over which length the temperature gradient should be less then 1°C if the apparatus is operated roperly. |
| Weight | 5.5 lbs (2.5kg) or less, depending on metal |
| Note: All Cells are intended for use in, and are dimensionally compatible, with the appropriate furnaces. | |
