X Cells - Stainless Steel Fixed-Point Cells

X Cells - Stainless Steel Fixed-Point Cells

Features

• Stainless steel casings help protect cells from mishandling
• Accuracies virtually identical to traditional-size quartz cells
• Can be maintained in fluid baths or dry-well calibrators

Have you wanted to use fixed-point cells but couldn’t justify the price? Have you been hesitant because of complex realization procedures or the fragile nature of traditional cells?

Hart’s new X Cells solve all these problems. They provide primary standards performance, are nearly unbreakable, and cost much less than traditional cell systems. The value of the water triple point X Cells is within 0.2 mK of traditional water triple point cells, and the gallium and indium cells include realized uncertainties less than 0.002°C.

Gallium and indium X Cells are constructed using a Teflon crucible containing a sample with purity of at least 99.9999%. The crucible is enclosed within a specially cleaned stainless steel envelope, which is evacuated and back-filled with high-purity argon.

Realizing these reference points couldn’t be easier. Special X Cell maintenance baskets allow the cells to be used in both standard baths and Micro-Baths, and a special sleeve is available for maintaining X Cells in Model 9103 dry-well calibrators.

Simply place the cell in the heat source, select the melt temperature, and within 30 minutes you’ll have an ITS-90 reference temperature all day long with stability of ±0.001°C. Once you finish using the cell, just set the freeze temperature and within minutes the cell is again ready for another realization. What could be easier?
