CRS ZPure™ M gas filters

Find out more about Chromatography Research Supplies (CRS), now part of the Trajan family of brands.

Pure gas is a critical requirement in gas chromatography, spectroscopy, optics, lithography, and numerous other applications in manufacturing and analytical laboratories. The ZPure™ M filters remove a wide range of contaminants to trace levels. The ZPure M filters are 3800 cc canisters that have the benefits of higher flow rates, larger capacities, and are refillable in most versions.

Features and benefits

High-efficiency in-line traps with outstanding capacity.
High quality activated adsorbents for long purifier life and efficient contaminant removal.
Filter lifetime is dependent on quality of incoming gas, and the flow rate.
Made from 316 stainless steel.
1/4" stainless steel compression or 1/2" VCR fittings.
Individually leak-tested.

Recommended applications

It can be used to purify inert gases, He, Ar, N₂, and H₂, in larger capacities. It is recommended for any application requiring ultra-pure gas free from contaminants, and has worked well in semi-conductor applications.
