Varian 525 Cold Cathode Vacuum Gauge

$350.00

Manufactures Description:
The Varian, Inc. Model 525 Cold-Cathode Gauge Tube measures pressures from 1 × 10-8 to 1 × 10-2 torr and has excellent repeatability, accuracy, and reliability. Sudden exposures to atmospheric pressure will not cause any damage, because there is no filament to burn out.

The Model 525 Gauge is similar in construction to the inverted magnetron gauge, and so it can be started at very low pressures, where ordinary cold-cathode gauges are difficult to start.

Expander De-202 with Dewar

$1,750.00

This is an Air Products 254469025 Expander De-202 with Dewar.
Specifications:
– Factory set for 60 HZ operation

Per product manual online: Cold head (expanders) are two-stage cryogenic refrigerators that operate on the Gifford-McMahon refrigeration cycle. Each uses helium gas from a helium compressor to produce the cold temperatures. Electricity to power the cold head�s valve motor is supplied from the compressor by the cold head cable. To be functional, the cold head is fitted with other parts or equipment so it can remove heat from the connected interfaces. Applications include laboratory systems for test sample cooling, cryopumps for clean, high-vacuum service and shield coolers and recondensers for cryogenic conservation, as in magnetic resonance imaging (MRI) medical diagnostic instruments.

The typical, complete operating system, using SCAI standard components, also requires and consists of the following pieces which are not included and must be soruced elsewhere : a helium compressor, interconnecting gas lines, interface attachments, and optional instrumentation.
