7.3 ACCESSORIES
Accessories are devices that perform a secondary duty as an aid or refinement to the primary unit.
Refer to the Lake Shore Temperature Measurement and Control Catalog for details. A list of
accessories available for the Model 331 is as follows:
Model Description
Of
Accessories
106-009
*
Heater Output Connector
. Dual banana jack for Heater Output.
G-106-233
*
Sensor Input Mating Connector
. 6-pin DIN plug for Diode/Resistor Input; 2 included.
106-739
*

112-334
Model 331/332 Sensor/Heater Cable Assembly - 10'.
Cable assembly for 2
diode/resistor sensors and Loop 1 heater. Approximately 3 meters (10 feet) long. See
Figure 7-1.
112-335
Model 331/332 Sensor/Heater Cable Assembly - 20'.
Cable assembly for 2
diode/resistor sensors and Loop 1 heater. Approximately 6 meters (20 feet) long. See
Figure 7-1.
115-006
*
Detachable 120 VAC Line Cord.
3003
Heater Output Conditioner.
The heater output conditioner is a passive filter which further
reduces the already low heater output noise of the Model 331. For details, refer to
Paragraph 7.4 and see Figure 7-2.
4005
IEEE-488 Cable Kit.
One meter (3 feet) long IEEE-488 (GPIB) computer interface cable.
Includes extender required to use both IEEE cable and relay terminal block
simultaneously.
CAL-331-
CERT
Instrument recalibration with certificate.
CAL-331-
DATA
Instrument recalibration with certificate and data.
ES-2-20
Stycast
®
Epoxy 2850-FT, Catalyst 9 (20 packets, 2 grams each)
. Stycast is a common,
highly versatile, 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 temperatures. 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 0.312 diameter × 0.005 inches.
ID-10-56
Indium Disks are 0.562 diameter × 0.005 inches.
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 contact 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 0.005 × 2 × 2 inches.
GAH-25
Apiezon
®
“H” Grease, 25 gram Tube
. It is designed for general purposes where
operating temperatures 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.
