Description
PermaProtect® – Specialty Gas Pre-treatment System
Prevents contamination of calibration gas mixtures
PermaProtect® creates a strong, impenetrable physical barrier between the desired specialty gas mixture and aluminum industrial cylinders. This treatment system helps maintain calibration mixture stability for many common gas mixtures (see Trace Element chart).
- Prevents contamination of specialty gas mixtures
- Provides long-term stability for calibration gas mixtures
PermaProtect® offers the ideal containment solution for the specialty gas industry by specially treating the internal surface of the aluminum industrial cylinder. First, the inside walls are polished to a mirror-like finish, then proprietary treatments are applied to the highly polished internal surface to protect contents from contamination.
PermaProtect® can be applied to these specific models of aluminum industrial cylinders: N-33, N-150, and N-265.
How do we add PermaProtect® to aluminum cylinders?
- First, the aluminum cylinder’s internal surface is polished to a mirror-like finish (Ra ≤ 0.05 μm).
- Then proprietary treatments are applied to the internal surfaces of the cylinder wall to maintain calibration mixture stability and prevent contamination.
