Rotary Evaporator Vacuum Pumps

Vacuum pump for rotary evaporator found in.

Rotary evaporator vacuum pumps. Turn on the vacuum. The gauge on the vacuum pump should read 27 in hg if the system is not leaking. Rpm regulated pumps have speed adjustment that stops pumps completely when vacuum level is reached. The new seal system speed regulated vacuum pumps as well as the new generation of high performance condensers ensure the highest solvent recovery increase the lifetime of a rotary evaporator and vacuum pump and reduces residue in the ambient atmosphere.

At the same time you save up to 90 of energy costs. No matter what solvents low or high boiling ones the pump s technology has to ensure a trouble free evaporation without superheating. The vacuum pump makes all the difference for the professional preparation of samples with rotary evaporators. Welch vacuum offers a wide range of vacuum pumps and systems suitable for different flask sizes allowing you to achieve ultimate vacuum levels of 75 to 1 mbar 56 3 to 0 75 torr and flow rates of up to 138 l min 4 87 cfm in your rotary evaporators.

Other vacuum pumps are recommended for solvents with low or medium boiling points and have suction capacity up to 3 rotary. Automated diaphragm vacuum systems can help you save both sample and time. Glassware used in the vapor stream and condenser can be simple or complex depending upon the goals of the evaporation and. Applying vacuum using a pump is either helpful or necessary in most rotovap applications as it reduces the pressure within the system this lowers the boiling temperature of the solvent resulting in faster evaporation and safer rotary evaporator operation.

Applying vacuum using a pump is either helpful or necessary in most rotovap applications as it reduces the pressure within the system. Vacuubrand rz2 5 vacuum pump rotavapor r 100 rotary evaporator laboport diaphragm pumps self cleaning dry. Rotary evaporator vacuum pumps resists chemcials and can be controlled manually or with valve operated vacuum controllers. Make sure the release valve at the top of the condenser is turned to the closed position.

The vacuum system used with rotary evaporators can be as simple as a water aspirator with a trap immersed in a cold bath for non toxic solvents or as complex as a regulated mechanical vacuum pump with refrigerated trap.
