GAN-25
Apiezon
®
“N” Grease, 25 gram 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 which 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.
HTR-25
25
Ω
Cartridge Heater.
The heater features precision-wound nickel-chromium resistance
wire, magnesium oxide insulation, two solid pins, non-magnetic package, and has UL and
CSA component recognition. The heater is 25 W, 6.35 mm (0.25 inch) diameter by 25.4 mm
(1 inch) long. The 25 W rating is in dead air. With proper heat sinking, the cartridge heater
can handle many times this dead air power rating.
HTR-50
50
Ω
Cartridge Heater.
The heater features precision-wound nickel-chromium resistance
wire, magnesium oxide insulation, two solid pins, non-magnetic package, and has UL and
CSA component recognition. The heater is 50 W, 6.35 mm (0.25 inch) diameter by 25.4 mm
(1 inch) long. The 50 W rating is in dead air. With proper heat sinking, the cartridge heater
can handle many times this dead air power rating.

RM-1/2
Half-Rack Mounting Kit for One Model 331 Temperature Controller.
Half-length
mounting panel and mounting ears to attach one Model 331 to a 483 mm (19-inch) rack
mount space. See Figure 7-3.
RM-2
Dual Mounting Shelf for Two Model 331 Temperature Controllers.
Mounting shelf to
attach any two 5.25-inch tall half-rack instruments side-by-side on a 483 mm (19-inch) rack
mount shelf. See Figure 7-4.
VGE-7031
IMI-7031 Varnish (formerly GE 7031 Varnish) (1 pint can)
. IMI-7031 Insulating Varnish
and Adhesive possesses electrical and bonding properties which, when combined with its
chemical resistance and good saturating properties, make it an excellent material for
cryogenic temperatures. 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).

. 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:
