Electrical Liquid Nitrogen Cryostat

The Electrical Liquid Nitrogen Cryostat from Xiamen Dexing Magnet Tech. Co., Ltd. offers researchers a fast and reliable solution for conducting low-temperature electrical measurements. Leveraging liquid nitrogen as the cooling medium, the system can cool samples down to cryogenic temperatures (as low as 65K) within 20–25 minutes. This makes it an efficient platform for advanced material studies involving resistivity, magnetoresistance, and Hall effect.

With a vacuum-sealed environment, stable temperature control (±0.01K), and customizable sample holders and connectors, this cryostat is designed for accuracy, repeatability, and versatility across scientific research and industrial applications.

The electronic liquid nitrogen cryostst uses liquid nitrogen as the cooling medium and is able to quickly cool the sample to liquid nitrogen temperature in a short time, only about 20 minutes, greatly reducing the experimental preparation time. This thermostat is especially suitable for use with electromagnets to complete the electromagnetic testing of sample materials, resistivity, magnetoresistance, Hall effect, etc. It provides a convenient and efficient electromagnetic test platform for researchers.

When using the electronic liquid nitrogen thermostat, just pour the liquid nitrogen into the liquid nitrogen chamber inside the thermostat, and by carefully adjusting the gap between the temperature control plug and the cold finger, the heat leakage of the cold finger can be maintained at a stable value. Subsequently, with the help of the DXTC-290 thermostat, the heating output power is precisely regulated, so that the temperature of the low temperature thermostat can change rapidly between 80K and 600K, and can quickly stabilize to the set target temperature. It is worth mentioning that if the thermostat is equipped with a step-down option, its temperature range can be further extended to 65K and can be stable at this low temperature state.

◆ With a wide temperature range from 65K to 500K, and the option to expand to 700K, the efficient and fast cooling capability provides a strong support for experiments.

◆ The sample is placed in a vacuum chamber, which effectively isolates external interference and creates a stable and pure environment for the experiment.

◆ The vacuum interlayer is equipped with low-temperature adsorbent, which effectively prolongs the holding time of the vacuum, and also prolongs the use time of liquid nitrogen, reducing the experiment cost.

◆ PT100 platinum resistance with good stability and high repeatability is used as the temperature sensor to ensure the accuracy and reliability of the experimental data.

◆ A variety of choices to meet different test requirements;

◆ Easy to add liquid nitrogen during use;

◆ Equipped with electric sample rack, which is equipped with pluggable sample card and convenient and beautiful terminal, greatly simplifying the sample installation and wiring process. ◆ Provide customized services, can be personalized design according to the specific requirements of customers, to meet a variety of special experimental needs.

◆ The thermostat comes standard with 8 measuring leads, which can be expanded to 32 as needed, providing ample connection options for experiments.

Remark:

1: All standard electrical cryostats are shipped with only one sample holder.
2: Can be customized according to customer requirements.

Note：

1. All electronic cryostats are shipped with two connectors. One is a connector for the installation of temperature sensors and heaters, and the other is an electrical connector for electrical measurements. When more electrical test wiring is required, it is necessary to add mounting holes or install one or more junction boxes.
2. In the low temperature thermostat electrical connector options, there is the T90-S option. The option is a coupling box housing mounted on the option, which is connected together as a whole to form a ground. The other is the T90-PTEF option. This option provides a teflon insulated connection between the housing and the installed connector, and the electrical properties of the housing and connector are independent of each other. Pay attention to this problem when choosing.
3. 700K high temperature thermostat can be customized.
4. Optional decompression accessories. Standard thermostats themselves have no special pressure relief. If the low temperature is 65K, you need to configure the corresponding decompression accessories.
