PermaProtect® Pre-Treatment System for Specialty Gas Mixtures

PermaProtect Pretreatment systemAdd PermaProtect® for calibration standard mixtures!

Cyl-Tec’s specialty gas pre-treatment system – called PermaProtect® – is a proprietary process especially developed for aluminum industrial cylinders that provides prevention of contamination for calibration gas mixtures.

PermaProtect® also provides long-term stability. The internal surface of the aluminum cylinder goes through a special process during manufacturing. First, the inside walls are polished to a mirror-like finish, then proprietary treatments are applied to the highly polished internal surface to protect from contamination and ensure constant purity.

Available for our most popular aluminum cylinder sizes: N-33, N-150, and N-265.
