Premium Water Triple Point Cells - Borosilicate Glass

These Premium Cells can be calibrated to an uncertainty of +/- 0.000070°C (0.07mK) A11-50-270*, A13-50-270*, B11-50-270, B11-65-270*, B13-65-270, B16-65-270 *also available in Quartz Glass.

Reproductilibity

The equilibrium temperature of a cell will repeat to within ±0.000,02°C of the mean equilibrium temperature.

Stability

After equilibrium is reached, the mean temperature of the inner melt of an ice mantle will remain constant to within ±0.000,01°C for as long as the mantle can be preserved (up to 90 days in some instances).

Further Laboratory Water Triple Point Cells

These Cells have shorter immersion depth and can be calibrated to an uncertainty of ±0.000100°C (0.1mK). B12-40-210, B12-46-210.

Accuracy

The equilibrium of temperature of the Jarrett-Isotech Triple Point of Water Cell is within ±20μK of the 2005 definition as described in CCT/05-07/rev(2). Isotopic Analysis can be provided to give the exact composition within ±3μK.
