More from Accessories & Modules
- Varnish
VGE-7031 insulating varnish and adhesive is used to bond and anchor sensors and wire at cryogenic temperatures. It is rated to 423 K, has a dry dielectric strength of 118 kV/mm and a volume resistivity above 1 x 10^15 ohm metres. It dries tack-free in 5 to 10 minutes at 298 K.
- Grease
Lake Shore offers low-temperature and high-temperature grease for installing and fastening sensors where a removable joint is wanted. Apiezon type N melts at about 303 K and suits cryogenic work, while type H is rated to about 513 K. Both have very low vapour pressure for vacuum use.
- Miscellaneous Cryogenic Accessories
Lake Shore supplies assorted cryogenic accessories, including heat sinks, sample holders, cartridge heaters and vacuum feedthrough products. The HTR-50 cartridge heater is rated 50 W at 50 V into 50 ohms, and the HTR-25-100 is rated 100 W at 50 V into 25 ohms.
