How to Safely Evaporate Explosive Solvents Since 1959, Organomation has been a leading provider of sample preparation solutions and equipment. We strive to create long-lasting equipment with safety and reliability as the top priorities. Many users of Organomation equipment work with highly flammable solvents such as Hexane and Diethyl Ether. That’s why we created a positive pressure purge device as an optional safety item to each of our evaporators and extractors. This positive pressure purge device, also called a Z-Purge, allows users to safely concentrate samples containing these highly flammable solvents, without the risk of explosion. The Z-Purge uses both pressurization and purging to protect against an explosion. Pressurization is an affordable yet effective alternative to intrinsically safe or explosion proof equipment. This device works by maintaining a small flow of inert gas in the heating unit, creating a positive pressure gradient within the enclosure. This prevents solvent vapor from entering the heating unit and igniting. As an additional protection measure, the concentrator is continuously purged with inert gas throughout the entire evaporation process, in order to flush out any stray solvent vapor. Each Z-Purge device comes with a pressure gauge and control valve to monitor and maintain pressure within the heating unit. The purge system is not tied to instrument operation, so the evaporator can be operated without a Z-Purge in low-risk environments. The Z-Purge can be added to all Organomation instruments, including our full line of nitrogen blowdown evaporators as well as our large-scale solvent evaporators and extractors. For nitrogen blowdown evaporators, the purge line can either be connected to the main nitrogen blowdown line, or to a separate clean air line to conserve nitrogen gas. If you have any questions on the Z-Purge device, or if you’re not sure whether your application requires one, please reach out to sales@organomation.com or call 978-838-7300 to speak to one of Organomation’s sales technicians.
