Selected Add-Ons

    The 20L ECO Series Rotary Evaporator is a full scale system meant to fulfill the needs of large volume production. Featuring all PTFE valves for extreme chemical resistance, the 20L ECO gives users the ability to recover large amounts of solvent in a smaller footprint with highly improved functionality. All BVV ECO rotovaps feature high efficiency valves and drain ports making it easy to directly inject solution continuously without the need to stop the system or release vacuum to drain. The temperature and rotation speed are easily controlled from a single digital interface. Our rotovaps are a fraction of the price of more costly systems with the same functionality and evaporation efficiency.

    “Continuous Feed” Operating Procedure:

    This procedure is the most efficient way to run a rotovap. It will give you the fastest speeds, with minimal heat load to the chiller. This procedure is meant to be a basic starting point for anyone new to using rotovaps. It assumes you are evaporating an ethanol solution for recovery and reuse of the ethanol. Once you have mastered this procedure, you can begin adjusting the parameters to suit your specific needs.

     

    • Clean and assemble the unit. Make sure all pieces are cleaned and sterilized using an alcohol solution.
    • Connect the chiller to the condenser and set it 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 the vacuum pump to the cold trap and connect the cold trap to a vacuum port on rotovap.
    • Turn on the heat bath and set it to 40C (113F).
    • Once the heat bath, chiller, and cold trap have reached desired temperatures, turn on rotovap motor and set the speed to approximately 100 RPM (does not have to be precise).
    • Start the vacuum pump and allow the vacuum to pull down for a few minutes before injection.
    • Once the 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
    • the 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 the injection valve this time but continue to allow the 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.

    ***Note: All units are inspected for broken glass or parts before the unit is shipped. If the unit arrives damaged or glass is broken (this does not include minor imperfections or scuffs in glassware), the Customer MUST contact BVV™ within 3 days of delivery to file a claim and receive a replacement part. If the customer DOES NOT contact BVV™ within 3 days of delivery responsibility for replacement parts falls on the customer and they must pay for replacement pieces.***
