The environment was temperature-controlled but subject to minor vibrations from nearby equipment.
The regulator performed admirably under these conditions. The pressure remained incredibly stable throughout the calibration process, even as the cylinder pressure decreased. I experienced none of the surging or pressure creep that I’ve encountered with lesser regulators.
Setup was intuitive, requiring no special tools or elaborate instructions. After securely connecting the regulator to the oxygen cylinder, achieving and maintaining the desired delivery pressure was simple. No noticeable leaks or other malfunctions surfaced.
Extended Use & Reliability
After three months of regular use, the VWR High-Purity Single-Stage Gas Regulators, Stainless Steel 3001160 continues to perform flawlessly. I use it almost daily for various analytical tasks, including gas chromatography, mass spectrometry, and elemental analysis. It continues to maintain consistent pressure over long periods.
There are no visible signs of wear or corrosion. The stainless steel body resists scratches and stains, and the gauges remain clear and accurate. I periodically check the fittings for leaks, but so far, everything remains tight and secure.
Maintenance is straightforward. I simply wipe down the regulator with a clean cloth and check the inlet filter for any debris. Compared to previous regulators I’ve used, the VWR High-Purity Single-Stage Gas Regulators, Stainless Steel 3001160 far surpasses them in long-term reliability and ease of upkeep. It has truly exceeded my expectations.
