Turn ON the main pressure (valve 1) and check that the vacuum gauge reads ~-950 mTorr, then turn ON the blue pump valve (valve 2). 5. If the unit is attached to a mechanical vacuum pump, check that the pump is OFF and top valve on the rotovap manifold (valve 3) is OFF. Turn ON the vacuum pump and check that the vacuum can reach <50 mTorr. 6.
9. Make sure the vacuum pump located next to the rotary evaporator is connected to the condenser. Make sure the release valve at the top of the condenser is turned to the closed position. 10. Turn on the vacuum. The gauge on the vacuum pump should read 27 in Hg if the system is not leaking. 11.
Vario pumps are made by VacuuBrand and functionally run less cfm while under set vacuum control to fully eliminate any chemical vapors in the room. Using a ipd15 or even central vacuum arrangement xds35i (higher cfm) pump will require a larger chiller or a larger central chiller.

Rotary evaporator also called rotavapor or rotovap, is a commonly used lab instrument in a chemistry laboratory, mainly used for concentration, crystallization, drying, separation and solvent recovery in a pharmaceutical, chemical, and pharmaceutical industries. The principle is: constant temperature heating under vacuum condition makes the rotating bottle rotate at constant speed, and the .
The rotary evaporator with positive air pump can keep the material from being polluted in the natural state. It is widely used in the deodorization, decolorization and purification of high value-added materials.
Any recommendations on what robust vacuum pump to attach to a rotary evaporator. I have tried several but they either die in a few years or require constant maintenance (oil pumps).
A rotary evaporation (rotovap) uses precise engineering to effectively remove solvents from a sample using evaporation. Most rotovaps make use of a vacuum and pressure control monitor to precisely control pressure within your system, increasing evaporation efficiency.
The vacuum pump makes all the difference for the professional preparation of samples with rotary evaporators. No matter what solvents, low or high boiling ones, the pump's technology has to ensure a trouble free evaporation without superheating.
