Finishing extracts is hard on a vacuum pump. Most fall by the wayside, worn down by the corrosive substances inherent in such applications. That's where the ULVAC DTC-41 diaphragm pump shines through. This is among the most durable pumps in the industry, which makes it perfect for rotary evaporation and off-gassing applications.
Over the past two years, Ai Vacuum—an industry leader in post-processing equipment, has become the top seller of DTC-41s in North America. As a result, the company is pleased to announce that this outstanding pump is now available with UL/CSA certification. Manufactured in Japan, the DTC-41 will outlast almost any other vacuum pump on the market. Why? Its two-stage PTFE diaphragms resist corrosive substances and solvents.
There are lots of other features, too. It's air-cooled, so it's free from any installation requirements. It's also oil-free, meaning it requires little maintenance. This saves you time, money, and worry about cross-contamination. Moreover, since it produces no fumes or contaminants, it's eco-friendly. All the components exposed to vacuum are coated with PTFE. This specialized plastic resists corrosive gases and organic solvents. So, it won't be worn down as a normal pump would. It's built to last.
These features make the pump perfect for several applications. These include rotary evaporation, vacuum filtration, vacuum drying systems, evaporating systems, vacuum concentration, laser-gas circulation, medical and pharmaceutical equipment, working with centrifuges, and more. It's pumping rate is a powerful 1.62 cfm. As a result, it only takes six minutes to pump down a 0.9 cu. ft. vacuum oven. It even comes with a free, 3-ft ? in. food-grade, silicone vacuum tube.
How does a diaphragm pump work? It has two membranes or diaphragms. These flex and relax in a coordinated fashion, opening and closing the exhaust valve and the suction valve rhythmically, and in this way constantly move media along. The diaphragms are coated with special plastics. These protect them and so allows the pump to work with corrosive gases and liquids. Moreover, a diaphragm pump's drive space is hermetically sealed. This protects its internal components. Additionally, with no sliding parts, this pump is free of abrasion.
