Check Valve: What is it? How Does It Work Types Of

A check valve is a safety device designed to allow fluids and gases to flow in one direction. Under pressure, fluids enter the valve at the inlet and exit through the outlet. Uninterrupted flow continues until the pressure drops, or the pump is shut down. An important aspect of check valves is their cracking pressure, the pressure at which the ...

How Rotary Evaporator Valve Work

How does the rotary evaporator work? The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).
