Working well with tissue and cell culture media, biological immunology reagents, or any liquid chemical waste, the systems are exceptionally versatile. But they work. A water aspirator that produces good vacuum when used alone may not produce adequate vacuum when used in a lab with other simultaneous users, as the water pressure may be sufficiently reduced to compromise vacuum generation, says Coffey. For corrosive applications, choose a diaphragm pump with a full fluoropolymer flow path. Only digits are allowed. If you wanted to make one rather more environmentally friendly, youd keep a well-stocked dry ice condenser in line with it to trap out the solvent vapors before they go down the drain (which is what your rota-vap should have on it, anyway), but even with that, youre always going to be turning the water flow into a waste stream. Aspirators use a vacuum power to aseptically dispose of supernatant fluids from a variety of laboratory vessels. While suitable for use in rotary evaporation or filtration systems using funnels or solid-phase extraction cartridges, water aspirators do not reach the deeplevel vacuum required for certain applications, such as evaporating high-boiling-point solvents, according to Jason Wagner, vice president of marketing in North America at BCHI Corporation (New Castle, DE).

If so, look for pumps with corrosion-resistant flow paths. Update to Avantors response to the coronavirus (COVID-19) pandemic. And by eliminating the water use and treatment costs associated with an aspirator, the initial cost of a vacuum pump potentially can be recovered in a few years. This biosafety cabinet is a must for each BSL lab. Am I concerned about emissions from vacuum applications ?
This is a rebuild kit for the USA Lab UVP Vacuum Pumps. Please make sure that you are logged in to the site so that available stock can be displayed. These curves show the performance in the region between the ultimate vacuum and the pumping speed specifications. Ask for evidence, and then compare pumps and pump suppliers on that basis for price, delivery, service needs, noise levels, and similar characteristics. Integral check valve will also prevent backflow of water into the vacuum line. An environmentally friendly alternative, vacuum pumps completely avoid the issues of water waste and contamination. A rotary vane, diaphragm, or scroll pump is typically used as the roughing pump; by creating a vacuum of 1 Torr, for example, 99.9% of the air molecules have been removed (1 Torr out of 760 Torr), thereby enabling the turbomolecular pumps to continue pumping down to the desired levels needed for detection, say, 108 to 1010 Torr. Accessories are available for many pump models that will capture vapors either before or after the vacuum pump. The oil in these pumps is used to lubricate and seal the pumps. Pressing the button applies the vacuum.

We use that for pulling out residues of water or organic solvents from our compounds. I ran around to the other side of the lab, where a new Japanese post-doc had taken up residence. And an oil pump can achieve a substantially deeper vacuum; however, Wagner points out that oil pumps also require more maintenance and can become contaminated. So much has changed during this unprecedented time, except your ability to count on Avantor. No matter what methods or technology you use, Avantor offers a comprehensive catalog of the equipment, reagents, chemicals, consumables, tools, and other products you need every day. An aspirator is basically a narrowing tube that hooks up to a hard-spraying water tap and has a sidearm fitting. Armen I. Malazian is with the Department of Land, Air and Water Resources at the University of California, Davis; e-mail: [emailprotected]. Numerous laboratory and industrial processes use solvents to separate substances and samples from each other.
