Vacuum System Supplies

Scientific Instrument Services offers a wide range of supplies and accessories for vacuum systems for mass spectrometers, electron microscopes and other instruments.

Vacuum Pumps (Rough Pumps and Diffusion Pumps)

Edwards and Alcatel lines of rough vacuum pumps and the Edwards line of Diffusion pumps. These are the most widely used vacuum pumps in the mass spectrometer and scientific instrument communities.  Repair kits also available. Call for ordering larger pumps not listed here.

Vacuum Pump Hose

Both wire reinforced and PVC cord reinforced vacuum hose for use with vacuum pumps. Both of these hoses are transparent for easy viewing.

Gaskets and 'O' Rings

A complete selection of gaskets and seals for your vacuum system. Gold, Viton, Silicone, Buna, PTFE, and Kalrez 'O' rings available.

Vacuum Gauges

Bayard Albert  ion gauges are the industry standard for most high vacuum applications.  Gauge tubes, ion gauge controllers and gauge cables are available from SIS, including the new Granville Phillips Stabil-ion Vacuum measurement system Thermocouple vacuum gauge tubes and controllers used to measure the higher vacuum levels in areas such as directly on the vacuum pump.

Vacuum Pump Oils

Inland, Fomblin and Santovac vacuum pump fluids for rough vacuums and diffusion pumps. Apiezon oils and waxes are also available for sealing vacuum joints.

Vacuum Pump Filters and Traps

A large number of vacuum pump filters.  Foreline traps, which are placed between the rough vacuum pump and the diffusion pump (or turbo pump), protect your vacuum chamber from oil back streaming from the vacuum pump. Exhaust filters are also available to prevent the vacuum pump exhaust from contaminating the laboratory air.  A two-stage system is highly recommended in areas where it is not possible to exhaust the vacuum pumps outside of the laboratory.

Vacuum Pump Fittings

A complete collection of the NW fittings for joining your vacuum pump components.  In addition to the standard products listed, SIS has the machine shop capabilities to custom modify or manufacture special components that you may require.
