Jan 16, 2020 After doing so, attach the flask and bump trap to the adapter portion of the rotary evaporator and secure it with a Keck clip. This feature will prevent your solution from entering the main part of the rotary evaporator. The last preparatory step is to lower the flask into the water bath using the joystick knob on the rotary evaporator.
Jan 29, 2021 Adding to that, a vacuum pump or aspirator is required to be attached along with a round bottom flask and bump trap which contains the sample that is to be concentrated. A commonly used device, a rotary evaporator is used by chemical laboratories for gentle and efficient removal of the volatile solvents from samples via evaporation.
May 19, 2009 I didn€™t have a rotary evaporator so I just attached a bain-marie to a cold-trap/chiller and a refrigeration vacuum pump (see photo). ... There is something called a bump-flask, which fits between the evaporation flask and the vapor duct, which can prevent small boil-overs from contaminating your rig, but they don€™t fit on our ...

Why is the flask spinned in rotary evaporation? When a flaks is filled, it can cause bumping which causes the material to go onto the bump trap that requires cleaning with the solvent used that makes the process longer and more use of solvents.
• A rotary evaporator (“rotovap”) is used to remove solvent from a sample in a round bottom flask or vial by boiling off the solvent under reduced pressure. Heating the ... Attach the bump (splash) trap to the joint on the rotator of the rotovap using a clip; then connect your round-bottom flask to the bump trap using a second clip.
