5L Rotary Evaporator with BVV™ Water Circulation Vacuum Pump

5L BVV™ Rotary Evaporator Beginner Setup includes all the necessary components to successfully perform solvent recovery via rotary evaporation. A cold trap should always be used inline between your vacuum system and application protect the pump from volatile vapors. The operator will have to provide ice or dry ice to cool the water in the water circulator bath, 2L of cubed ice or more every 10 minutes

The 5L BVV™ Rotary Evaporator is a tabletop model made for users who are looking for more capacity than the standard 2L but still need a smaller footprint compared to a 10L or 20L model. Designed with ease of use in mind, the 5L will separate solvents from mixtures with efficiency, and repeatable results making it the ideal rotovap for the majority of end users. With the ability to continuously fill and drain, users can quickly process gallons of solution. The double helix vertical condenser provides maximum surface area for condensation of vapors. PTFE seals on the entire system are made for maximum chemical resistance to ensure vacuum depth and lifespan of the system. 

This kit also includes the BVV™ Water Circulation Vacuum Pump and this Circulation and Vacuum Pump combines the best of both worlds by using the circulating water to pull a vacuum which requires no oil at all and has very low maintenance requirements overall due to this unique process and design. Each vacuum port on the unit pulls vacuum separately from one another so the user can use it for different applications at the same time or combined to increase the vacuum. This pump will also circulate water through the backports as needed to cool and application and dissipate heat as needed.

Rotovap Quick Start Guide

This guide gives basic quick start instructions for rotovaps. It is intended to provide a starting point for learning the process. Parameters should be adjusted to suit specific needs.

  • Clean and assemble unit. Make sure all pieces are cleaned and sterilized using an alcohol solution.
  • Connect chiller to condenser and set to 0C (32F). Always fill a rotovap condenser from the top down (chiller output to top of condenser, chiller input to bottom of condenser).
  • Connect vacuum pump to cold trap and connect cold trap to vacuum port on rotovap.
  • Turn on heat bath and set to 40C (113F).
  • Once heat bath, chiller and cold trap have reached desired temperatures, turn on rotovap motor and set speed to approximately 100 RPM (does not have to be precise). Keep in mind, higher RPM’s will increase evaporation power but also increase heat load.
  • Start vacuum pump and allow vacuum to pull down for a few minutes before injection.
  • Once vacuum has been pulled to a sufficient level (does not have to be precise but should be below 100 Torr), using the injection valve, very slowly inject approximately 500 mL of solution into evaporating flask and then close the valve. Allow this small amount to begin evaporating. You may see the chiller begin to rise in temperature, this is called “priming” the rotovap.
  • Once the temperature stops rising or all liquid is almost completely evaporated, open the injection valve again very slowly so that a small amount of liquid begins to enter the evaporating flask. Do not close injection valve this time but continue to allow solution to enter the evaporating flask. 
  • At this point you must try to match the input speed to the output speed. What this means is that you should be injecting the same amount of liquid into the rotovap that is equal to the amount of liquid dripping from the condenser into the receiving flask. You will know that the input speed and output speed are matched because the chiller will remain at a stable temperature. If the chiller begins to rise, then you are injecting too much liquid. Dial back the valve until the chiller stabilizes.
  • Once everything is stabilized, you may walk away from the rotovap if necessary. Check every so often to make sure temperatures remain stable and evaporation continues efficiently.
