This Edwards Pico Dry turbo molecular high vacuum system features a compound Edwards EXT-70 turbo-molecular pump backed with an oil-free diaphragm pump. The backing pump does not utilize oil or other lubricants in pumped volumes, which reduces the risk of contamination. The Pico Dry System eliminates the need for external controllers or additional backing pumps. Comes with NW40 inlet and a pumping speed of 65 l/s and requires an input of 115 VAC. These systems are totally rebuilt and are in excellent condition. These Edwards Pico Dry turbo molecular high vacuum systems come with a 90 day parts and labor warranty. We also have fittings, vacuum hoses and accessories to fit this system in stock ready for shipping. For Specifications see below.
