If you have just acquired a new rotary evaporator .
Atmar-Glass offers bump rotary evaporator traps, bump trays, rotary evaporation supplies, and a full selection of laboratory supplies and lab glassware.
Attach a glass "bump trap" which prevents any solution from entering the main part of the rotovap. Secure with a Keck clip. With a Keck clip attach the flask and bump trap to the adapter portion of the roto-evaporator. Lower the flask into the water bath. This helps to prevent the flask from disconnection. 2. Rotary Evaporator Operation
The rotary evaporator is composed of four components that function in unison: the rotor, condenser, heat bath, and solvent trap. A vacuum pump or aspirator are also attached to the rotary evaporator. There is usually a bump trap and round bottom flask to hold the cannabis.
1. Fit your sample to a bump trap of the appropriate size and attach with a keck clip 2. Attach sample-trap apparatus to the rotary unit, and secure to the rotary unit with the metal clip. 3. Turn on the power switch, on the right hand side of the water bath. Note that it is not possible to run the rotary unit without turning on the bath.
