As a medical and laboratory instrument parts manufacturer, S.I.S. manufacturers instrument parts for scientific instrument companies. Our specialty is filaments for mass spectrometers, x-ray equipment and other instruments utilizing a filament heater or emission wire. We can custom design and manufacture filaments to your needs from 10 to +10,000 units.

A growing part of our business is OEM manufacturing. Our capabilities include precision machining (CNC turning, swiss turning, and milling), tig and laser welding, vacuum brazing, filament manufacture, gold gasket fabrication, custom assembly, cleaning (sandblasting, tumbling, electropolishing and high purity cleaning), Finishing, CAD/CAM, inspection, and testing. SIS is ISO 9001:2008 certified. Contact us for information about our OEM programs.

General Laboratory and Cleaning Supplies

Products A wide variety of fine tools and cleaning supplies for the service of your scientific equipment, including Micro-Mesh fine abrasives for polishing and cleaning instrument parts, swabs and applications, Dust-Off, and a miniature spot welder. We also offer a broad line of Wheaton glassware and lab vials for your laboratory.
Our tool lines include Dremel, X-Acto, Panavise, Paasche, Microflame, Littletorch, General, Mettler, Diamond, Foredom and much more.

Short Path Thermal Desorption

Sample analysis is via thermal desorption techniques as well as a new technique called direct thermal extraction. In the direct thermal extraction technique, volatiles can be extracted from solid matrix samples, cryo-focused at the front of the GC column and subsequently analyzed. No solvent extraction or other sample preparation is required.
Designed and manufacturered by S.I.S.

Custom Software

We develop software for the simulation of particle optics used in engineering mass spectrometers and related equipment utilizing electric fields (SIMION), as well as other embedded instrument, PC, and web software.
We sell many mass spectra databases for identification of spectra obtained from your mass spectrometer (NIST/Wiley).
