How does the Whitley Workstation and airlock mix the correct gas mixture?
MECHANISM OF GAS MIXING To help understand the possible gas mixtures within the Whitley range of anaerobic workstations the following has been compiled to explain the fundamental differences. Whitley MG Workstation The Whitley MG500 and MG1000 workstations have been designed to operate from a bottle of anaerobic gas mixture. This is a world-wide industry standard gas mixture consisting of 80% Nitrogen, 10% Hydrogen and 10% Carbon Dioxide. This gas mixture is connected to the workstation and introduced into the chamber on demand. A pressure switch is set to maintain a small positive internal pressure. Any pressure drop within the workstation permits gas to flow into the unit. In addition, a forced gas injection timer delivers a small volume of gas at pre-determined intervals. This ensures that fresh gas is always being delivered into the chamber thus helping to maintain anaerobic conditions. For applications where knowledge of gas composition is critical, some gas bottle suppliers can p
