   Product Description    Specifications
The Isotech Model ITL-M-17725 Cryostat is a self-contained, mechanically-refrigerated, system with a main well to house one cell and two auxiliary wells for pre-chilling of thermometers. The cryostat temperature is steplessly adjustable from -36C to 42C with scale-divisions of 0.1C (interpolation possible) and 24 hour stability better than 0.05C measured by an SPRT in the well of a Mercury Cell inside the cryostat.

The cryostat has several unique features providing outstanding convenience and safety. The refrigeration system has sufficient capacity to bring a cell to operating temperature in about one hour. At operating temperature, the cooling rate about 1 Kelvin/minute and the heating rate is about 2 Kelvin/minute.

This permits rapid changed to be imposed on the temperature of the cell environment to a void excessive demands on the (low) heat-of-fusion energy of the mercury within the cell.

In addition, all temperature control is accomplished through control of refrigerant flow, providing inherently fail-safe operation. Indicators provided fro the cryostat are "POWER ON" and "COOLING".

The cryostat provides convenient conditions for operating mercury fixed point cells both in heating and in cooling mode.
