There are numerous vacuum pump applications for laboratories. To meet the requirement of laboratory usage, UNi-CROWN has developed a series of portable pumps for lab applications. Features include oil-less design, attached pressure regulator, filter, vacuum gauge, power cord, and switch. Pre-filter can prevent dirt particles and the liquid from being sucked into the pump. The appearance of our lab pumps are beautifully designed to match the lab environment and the suitability of their application in the lab are fully considered, so they are very suitable for laboratory use. LAB-10/20/30/300/400, SE Series, are available in AC 110V or AC 220V. Maximum vacuum degree is between 620~740mmHg. The open flow rates are from 20~220 LPM (at 60HZ), 16~176 (at 50HZ). The oil-less operation of this series is an environmentally friendly design. Applications: Vacuum Glove Box, Extraction Equipment, Tissue Culture, Suspended Solid Sampling, Degassing, Filtration for Microbiology, Cell Harvesting, Laboratory Instruments, Vacuum System, Vacuum Filtration, Vacuum Oven, Drying, the alternative to water jet vacuum pump, and various laboratory applications, Concentrators.
