RM-1
Rack mounting kit; mounting brackets, ears and handles to attach 1 Model 372 to a 482 mm
(19 in) rack mount cabinet
ES-2-20
Stycast® Epoxy 2850-FT, Catalyst 9 (20 packets, 2 g each). Stycast® is a common, highly versa-
tile, nonconductive epoxy resin system for cryogenic use. The primary use for Stycast® is for
vacuum feedthroughs or permanent thermal anchors. Stycast® is an alternative to
Apiezon® N Grease when permanent sensor mountings are desired.
ID-10-XX
Indium solder disks (quantity 10). Indium is a semi-precious non-ferrous metal, softer than
lead, and extremely malleable and ductile. It stays soft and workable down to cryogenic tem-
peratures. Indium can be used to create solder “bumps” for microelectronic chip attachments
and also as gaskets for pressure and vacuum sealing purposes.
ID-10-31
indium disks are 7.92 mm diameter × 0.13 mm (0.312 in diameter × 0.005 in)
ID-10-56 indium disks are 14.27 mm diameter × 0.127 mm (0.562 diameter × 0.005 in)
IF-5
Indium foil sheets (quantity 5). When used as a washer between DT-470-CU silicon diode or
other temperature sensors and refrigerator cold stages, indium foil increases the thermal con-
tact area and prevents the sensor from detaching due to vibration. It also may be used as a
sealing gasket for covers, flanges, and windows in cryogenic applications. Each sheet is
0.13 mm × 51 mm × 51 mm (0.005 in × 2 in × 2 in).
GAH-25
Apiezon® H grease, 25 g tube. It is designed for general purposes where operating tempera-
tures necessitate the use of a relatively high melting point grease. Melting point is 523 K
(250 °C). Can be removed using Xylene with an isopropyl alcohol rinse.
GAN-25
Apiezon® N grease, 25 g tube. General purpose grease well-suited for cryogenic use because of
its low viscosity. It is often used as a means of thermally anchoring cryogenic sensors as well as
lubricating joints and o-rings. Contains high molecular weight polymeric hydrocarbon additive
that gives it a tenacious, rubbery consistency allowing the grease to form a cushion between
mating surfaces. Melting point is 316 K (43 °C). Can be removed using Xylene with an isopropyl
alcohol rinse.
VGE-7031
IMI-7031 varnish (formerly GE 7031 varnish) (1 pint can). IMI-7031 insulating varnish and
adhesive possesses electrical and bonding properties that, when combined with its chemical
resistance and good saturating properties, make it an excellent material for cryogenic tem-
peratures. As an adhesive, IMI-7031 bonds a variety of materials, has fast tack time, and may
be air dried or baked. It is also an electrically insulating adhesive at cryogenic temperatures
and is often used as a calorimeter cement. When soaked into cigarette paper, it makes a good,
high thermal conductivity, low electrical conductivity heat sinking layer. Maximum operating
temperature: 423 K (150 °C).
Wire
Lake Shore cryogenic wire. Lake Shore sells the following types of cryogenic wire:
DT = Duo-Twist, MN = Single Strand, MW = Manganin, NC = Nichrome Heater,
ND = Heavy Duty, QL = Quad-Lead™, and QT = Quad-Twist™.
Lake Shore coaxial cable.
Lake Shore sells the following types of coaxial cable:
CC = Ultra Miniature Coaxial Cable, SR = Semi-Rigid Coaxial Cable, CRYC = CryoCable™.
