There are also interactive online vacuum pump selection guides available that ask a few questions about the planned use for the pump and recommend a series of pumps to satisfy a range of budgets. "It is not a glamorous technology but it is one that can affect the costs, comfort and convenience of your laboratory," says Coffey.
However, the high vacuum pumps that will evacuate the chamber to a much lower pressure don't function at atmospheric pressure. So we need to start with the mechanical pump and then use a high vacuum pump after the mechanical pump. The two high vacuum pumps that we will present in this course are cryogenic pumps and turbo molecular pumps.
Laboratory/filtration vacuum pumps are for use in the lab or anywhere a low vacuum is needed; typically offer both vacuum and pressure capabilities. Use rough vacuum pumps (or roughing pumps) for laboratory and industrial applications requiring a level of vacuum less than 10–3 Torr.
An aspirator is a type of ejector-jet pump, which produces vacuum by means of the Venturi effect.. In an aspirator, fluid (liquid or gaseous) flows through a tube that first narrows and then expands in cross-sectional area. When the tube narrows, the fluid pressure decreases.

Laboratory vacuum pumps are adaptable tools which can help many different engineers and research scientists. Labs routinely use laboratory vacuum pumps in order to do the following: Provide suction that drives the filtration or aspiration of suspended or liquid samples Control or induce solvent evaporation through the reduction of vapor pressure, like in concentrators, gel dryers, rotary .
This type of laboratory vacuum pump is a combination of the diaphragm and the rotary vane. The diaphragm will function a the gate to maintain negative pressure on the oil for the rotary vane pump. As a result, the vapors are eliminated; the oil is condensed. Compared to the standard rotary vane pump, you can change the oil every 300,000 hours.

Mechanical vacuum pumps used in laboratories pose many hazards. There are mechanical hazards associated with the moving parts. There are chemical hazards of contaminating the pump oil with volatile substances and subsequently releasing them into the lab.
Jan 13, 2016 · The vacuum pump functions by removing the molecules of air and other gases from the vacuum chamber (or from the outlet side of a higher vacuum pump if connected in series). While the pressure in the chamber is reduced, removing additional molecules becomes exponentially harder to remove. As a result, an industrial vacuum system (Fig. 1) must be .

Jun 15, 2015 · During laboratory evaporation, the main function of the Cold Trap is to collect harmful vapors before they enter the vacuum pump. For a vacuum pump that requires oil, collection of solvent vapors is essential to prevent them from collecting in the vacuum pump's oil. Also, if corrosive or water vapors collect in pump oil, the vacuum pump will .

Vacuum aspirators provide greater control with consistent and stronger vacuum pressure, leading to improvements in key lab applications. Where water aspirators fail to provide a deep enough vacuum for certain uses, vacuum pumps deliver. A simple dry lab pump can reach about 1 torr, which is certainly strong enough to handle most lab applications.
