Buy High Purity Components Here.

With the ebb and flow of the semiconductor industry, microelectronics facilities and others in the industry will find themselves with excess product on their shelves, or even may need to purge their inventories simply to stay in business.  Critical Systems has been able to help many companies by procuring that excess high purity component inventory. We buy large quantities of new components from these companies and offer it to our customers at tremendous discounts.

New and Pre-Owned High Purity Components

CSI has been selling new ‘surplus’ UHP components to budget savvy customers for over 12 years. CSI also offers refurbished components that have been used on professionally decommissioned Inert Gas Systems. As with all of our used inventory, CSI runs these components through an inspection procedure including a nitrogen purge, helium leak, and pressure decay checks.  Once testing is completed, documented, and double-checked, components are then repackaged for shipment.

Brands Carried

CSI’s components come from the leading manufacturers in the industry: Swagelok, Parker, BAR, Hamlet, APTech, Veriflo, Tescom, George Fisher, Asahi, Valex, Cardinal, Wika, Pall, Mykrolis, Entegris and many others.
