Apr 12, 2021 Claw Pumps (Dry, Booster): Pressure 1 x 10-3 mbar, Pumping Speed 100 – 800 m 3 /h (59 – 472 ft 3 /min) Claw pumps have two rotary claws that counter rotate. They are extremely efficient, reliable, and low maintenance, and often used in harsh industrial environments. The Claws come within 2/1000’’ of each other, but never actually touch.

What are Rotary Evaporators and How Do They Work?

Feb 25, 2021 What is Rotary Evaporation? Evaporation is a gentle, efficient way to remove solvents and the process of rotary evaporation is a reduced-pressure distillation. It involves placing a sample within a round-bottomed flask, which is then placed in the rotovap’s heated water bath and rotated. A vacuum pump reduces the pressure above the solvent.

When to use rotary evaporator? Explained by FAQ Blog

May 30, 2022 What is the purpose of the vacuum pump connected to the rotary evaporator? A vacuum pump is an important part of the rotary evaporator setup because it reduces the pressure within the system. This lowers the boiling temperature of the solvent enabling faster evaporation. One of the implications of this is you can work with a lower temperature ...

Nov 27, 2021 The rotary gear pumps use the action of the rotating gears or cogs to transfer the fluid. The rotating elements help in developing a liquid seal with a pump casting. This helps in creating a suction at the pump inlet. The fluid is drawn inside the pump and it is enclosed within the cavities of the gears which rotates inside the pump.
