What Are Rotovaps and How Can They be Used?

What Are Rotovaps and How Can They be Used?

A rotovap acts like a filter to separate the unwanted components in the extract as a final step to crude oil. The rotovap is a simple concept with a lot of moving parts. The material needs to be heated to the point of evaporation and then cooled and condensed. The process is like distillation but even more precise.

Selecting a Suitable Vacuum Pump for Your Rotary Evaporator

Apr 04, 2019 Within rotovap applications, there’s often the goal to make production as fast as possible. In terms of pumps, a “bigger is better” mindset is commonly adopted, where it’s assumed that the higher the flow rate, the faster the production. However, this can lead to problems such as pump damage and an inefficient process.

Jan 18, 2017 When operating a rotovap, following tips should be remembered. To remove algae gunk from the inside of a coiled water condenser, the condenser has to be removed from the rotovap and the coil is soaked in a dilute nitric acid solution for a few hours. After carefully rinsing the insides, the rotovap is reassembled.
