10K Closed Cycle Cryostat

        CCS (Closed Cycle System) refrigerator utilizes the principle of G-M thermodynamic cycle to compress and expand helium. The gas is expanded and cooled in the cold head, and the expanded low-pressure helium gas is returned to the compressor, and the cycle is repeated. The refrigerator consists of two stages, the first stage is used to cool the heat shield around the sample, and the second stage is used to cool the sample.

        The 10K closed cycle cryostat provided by Jinzhengmao Technology Co., Ltd. is a variable temperature and low temperature platform based on G-M refrigerators produced by domestic and foreign companies. Warm, easy to operate, and low maintenance cost.

Scope of use:It is mainly used for magnetic measurement, optical measurement, photoelectric reaction, light reflection, fluorescence and magnetoresistance in low temperature and vacuum environment.

Sdvantage:

※ Compact structure, high cost performance, no refrigerant consumption when reaching low temperature, long maintenance period, strong expansibility, and easy to use;

※ The sample is in a high vacuum environment or atmosphere;

※ Can be integrated with optical windows, a variety of optional window materials;

※ A variety of gold-plated oxygen-free copper sample holders can meet the measurement needs of different experimental requirements, and the sample holders can be quickly replaced;

※Suitable for electrical, optical and magnetic measurements in low temperature environments;

※Silicon diode thermometer or Cernox thermometer (used in strong magnetic field) is installed on the cold finger;

※The compressor can be air-cooled or water-cooled, and the maintenance cycle is long;

※A variety of options can meet the measurement needs of different experiments.

Integration Specifications And Parameters

Note: Optical holes can be opened in the middle of the optical sample holder, and the size can be specified by the user.

Sample Holder Options:

Optical window options:

Cable Options:

Connector Options:

Remark:

1: All thermostats are shipped with two connectors, one is for temperature sensor and heater installation, and the other is for other performance measurements. When more test wires are required, it is necessary to increase Mounting holes, or add one or more Breakout Boxes.

2: There is T91-S option in the above table, the terminal board and the shell of this option constitute the grounding as a whole, and the other is the T91-PTEF option, this option is the shell and the installed joint using PTFE board insulation connection, The electrical properties of the housing and the connector are independent of each other. This should be taken into account when selecting models.

Water cooler selection：

There are split and integrated options, please refer to the water cooler color page for details.

The standard configuration of mechanical pump and molecular pump is a mechanical pump. If higher vacuum is required, domestic and foreign molecular pumps can be selected. For selection, refer to the vacuum pump selection table.
