Monitoring Tank Locations
Lab Services monitors the quantities and locations of all gas cylinders ordered through the Lab Gas Program. We occasionally audit the gas cylinders on rent, so the location needs to be kept track of. Please contact Lab Services before moving gas cylinders (empty or full) from the location they were delivered to.
Gas Analysis
Certificates of analysis are available for any gas ordered through the Lab Gas Program. If an analysis is required, please inform us when placing your order.
