川口液化ケミカル List of Products and Services

This product is a cryostat that continuously flows liquid helium to cool samples. It supports optical measurements such as photoluminescence measurements and evaluations of optical semiconductors. The size of the optical entrance window can be manufactured from φ5 to φ50 mm. An optional low-temperature shield shutter can be installed to reduce the evaporation of helium at extremely low temperatures. Additionally, while quartz glass is the standard material, other materials for the window can also be used. 【Features】 ■ Continuously flows liquid helium to cool samples ■ The size of the optical entrance window can be manufactured from φ5 to φ50 mm ■ An optional low-temperature shield shutter can be installed ■ Other materials for the window can also be used (standard material is quartz glass) *For more details, please refer to the PDF document or feel free to contact us.

The "Liquid Helium Cooling Device for Electron Microscopes" is a cryostat that continuously flows liquid helium to cool samples. Since electron microscopes are sensitive to vibrations, thin stainless steel tubes are used for helium supply and return to eliminate external vibrations. To minimize the expansion and contraction of the sample holder due to cooling, heaters are installed throughout the heat exchanger to control temperature-induced expansion and contraction, ensuring that there is no "movement" of the sample even at high magnifications. 【Features】 ■ Minimizes the expansion and contraction of the sample holder due to cooling ■ Designed to prevent any "movement" of the sample even at high magnifications ■ The dedicated transfer tube adopts our original triple-tube design to reduce helium consumption *For more details, please refer to the PDF document or feel free to contact us.

The "GM Cryostat with Refrigeration Unit" is a device that allows you to easily achieve a temperature environment below 15K with the push of a button. It is capable of measurements such as magnetic resistance measurement and Hall effect measurement. The tail section can be made from non-magnetic materials (such as beryllium copper, FRP, brass, etc.) as an option, and it can also be used with a VSM (Vibrating Sample Magnetometer). Additionally, it can be rotated from 0 to 90 degrees without the need for a special stand, allowing it to be installed on an electromagnet. 【Features】 ■ Easily achieve a temperature environment below 15K with the push of a button ■ Capable of measurements such as magnetic resistance measurement and Hall effect measurement ■ Can be rotated from 0 to 90 degrees ■ Can be installed on an electromagnet without the need for a special stand *For more details, please refer to the PDF document or feel free to contact us.

The "liquid nitrogen cryostat" is a device capable of optical measurements such as photoluminescence measurements and evaluation of optical semiconductors. To reduce the consumption of liquid nitrogen, a needle valve is installed at the top flange to guide an appropriate amount of liquid nitrogen to the upper part of the sample holder, where temperature control is performed using a heater. The optical windows are standard in two or four locations, but designs can accommodate more windows if needed. Quartz glass is the standard material, but other materials for the windows can also be used. 【Features】 ■ Capable of optical measurements ■ Temperature control is performed using a heater ■ Optical windows are standard in two or four locations (can accommodate more windows if needed) *For more details, please refer to the PDF document or feel free to contact us.

Liquid nitrogen is a liquid at -196°C. At room temperature in the atmosphere, it appears to be in a boiling state, similar to a pot of hot water on the stove. To deliver such liquid nitrogen to a cooling tank, it can be poured in using a funnel-like drop-in structure or pushed in using nitrogen gas pressure in a "tokoroten" style. It would be convenient to have a device that automatically monitors the remaining amount of liquid nitrogen and supplies it automatically when it runs out. That is the "Automatic Liquid Nitrogen Supply Device." 【Features】 ■ Automatically monitors the remaining amount of liquid nitrogen ■ Capable of automatic supply when the liquid nitrogen runs out *For more details, please refer to the PDF document or feel free to contact us.
