Rotary Vane Vacuum Pumps come in either one-stage or two-stage. Typical volumetric flow rates are between 2 to 20 Cubic Feet per Minute (CFM). A Rotary Vane Vacuum Pump can generate a vacuum of about 1 milli Torr which is why they are preferred as a roughing pump for a plethora of vacuum …

A typical rotary evaporator has a water bath that can be heated in either a metal container or crystallization dish. This keeps the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser and is collected for easy reuse or disposal.

This machine is of the rotary drum filter type, but the filtering medium is applied on the interior of the drum which acts as its own container. The inner surface of the drum is divided into a series of fabric-covered panels, each forming a face of a polygon inscribed within the cylinder. The compartments thus formed connect individually with an automatic valve, which, in turn, applies vacuum ...

pump such as an oil-sealed rotary pump. Vacuum Units of Measurement Measuring vacuum, as with any kind of measuring, requires standard units of measure. Inches or millimeters of mercury, torr, and micron are three units of measure typically associated with the vacuum furnace industry. Other fields of vacuum use Pascals (Pa or kPa.)

Though vacuum generator 28, ultimately in communication with and drawing vapors from the rotary retort 20 via transfer pipe 23, may reduce the pressure to nearly zero pressure absolute, the preferred embodiment and method of use of vacuum generator 28 maintains between 2.25 mm Hg and 735 mm Hg vacuum in all of the apparatus including rotary ...

Vacuum Workholding is Often a Secondary Choice – Yes, vises and clamps are the preferred method of holding a workpiece due to theoretically unlimited clamping force, however thin parts aren't easily held with a vise. A vacuum chuck may be your only choice, but don't expect to be able to machine a part as aggressively as when using a vise.

A rotary evaporator (rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was evaporated under ...
