Edwards E1M18 Oil-Sealed Rotary Vane Vacuum Pump for Laboratory and Industrial Use
Product Description
The Edwards E1M18 is a single-stage oil-sealed rotary vane vacuum pump designed for laboratory and industrial vacuum applications including biotechnology workflows and molecular diagnostics requiring reliable low-pressure generation. This pump features a direct-drive motor coupled flexibly to the sliding-vane mechanism, ensuring smooth operation and extended service life.
Key specifications include:
- Ultimate pressure: 3 Pa, suitable for applications demanding high vacuum such as bioprocessing containment and synthetic biology setups
- Inlet connection: DN25 ISO-KF (NW25), allowing integration with standard vacuum lines and instrumentation common in cell imaging and analytical research
- Outlet connection: 15 mm hose nozzle with 3/4-inch BSPP female fitting
- Gas ballast: Manually adjustable multi-turn valve to reduce vapor condensation and oil contamination, essential for processing condensable vapors in molecular cloning and biomanufacturing
- Oil system: Internally lubricated with Edwards Ultragrade Performance 19 oil (maximum capacity 1.4 L), including oil distribution valve to prevent oil back-suction during shutdown
- Motor: Totally enclosed with dedicated fan cooling and automatic thermal-overload protection to safeguard against temperature-induced failures
- Construction: Mounted on an aluminum-alloy baseplate with rubber pads for vibration isolation
- Monitoring: Reservoir sight glass for oil level and condition checks, with separate fill and gravity-drain ports for maintenance ease
- Electrical: Operates on 230 V, 60 Hz, with 5.5 A current draw
This vacuum pump is widely used in biomedical engineering, clinical diagnostics, and research laboratories where stable vacuum levels and contamination control are critical. Its design supports applications like live-cell imaging chambers, fluorescence analysis setups, and critical biomanufacturing stages. The adjustable gas ballast valve makes it particularly effective for environments dealing with humid or vapor-laden gases, common in molecular biology and synthetic biology research workflows.
Included with the Edwards E1M18 are the oil mist filter (EMF20), user manual, and a 230 V power cord. This pump is backed by a 30-day warranty and rigorous factory testing, ensuring dependable performance in demanding laboratory environments.
