Sep 23 2019nbsp018332A crucial part of most rotovap setups is the pumpWe discussed pumps in a previous post where we covered general considerations such as vacuum pressure pump speed and vacuum controlHere we’ll look at which type of pump you should use.

The FA20D engine used a hotwire slotin type air flow meter to measure intake mass – this meter allowed a portion of intake air to flow through the detection area so that the air mass and flow rate could be measured directlyThe mass air flow meter also had a builtin intake air temperature sensor.

Vacuum distillation is often used in large industrial plants as an efficient way to remove salt from ocean water in order to produce fresh waterThe ocean water is placed under a vacuum to lower its boiling point and has a heat source applied allowing the fresh water to boil off and be condensed.

We use rotovaps for two primary purposes 1 Think of unpredictable ingredients in a mixture for instance focusing on the flawless and fresher flavors of blood.

What is a rotovap A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporationA rotovap acts like a filter to separate the unwanted components in the extract as a final step to crude oilThe rotovap is a simple concept with a lot of moving parts.
