Feb 15 2021 A rotovap or rotary evaporator is a device which is employed for the gentle and efficient removal of solvents from samples via evaporation and are typically used to remove solvents from a mixture of chemical compoundsHow Ecodyst Evaporators Differ from Cold Traps for Vacuum Pumps January 13 2022 537 am SuperFast Solvent Recovery.
Connect the bump trap to the rotovap and secure with the metal clip or a keck clip depending on the model of rotovap pictured belowThe bump trap should be kept clean it provides a receptacle in case the solution splashes or boils beyond the flaskA clean bump trap can allow for recovery of.
Gather the necessary glassware and chemicals to set up the cold trap as shown belowThis picture is a common set up used to filter a solution using a Buchner funnelThe top of the cold trap is connected to the vapor source reaction vessel filter flask vacuum oven rotovap etcand the side is connected to the vacuum trap.
Ideally you should have pump attached to dry iceacetone trap followed by a cold water condenser from the rotovapThere are several reasons to have a cold trapProtection of the pump is one of themThe other reason is that a pump can maintain deep vacuum OR pump large volume of material but not both.
Jan 13 2022 Cold traps are generally placed between the vacuum pump and the rotovap to safeguard the pump from any additional contaminationCold traps are usually a critical element of standard rotovaps as they catch any vapors that pass through the condenserCold traps are lined with lead and are connected to both the suction container and the vacuum.
Jul 08 2021 Always use a cold trap in between the rotovap and the pumpNever use a liquid nitrogen to cool the trap as this can cause condensation of liquid oxygenIf a trap becomes clogged immediately shut off the vacuum disconnect the trap and ensure it is open to atmosphere to prevent explosion.
Mar 02 2021 A rotovap setup can be quite complexYou have your basic components including the rotary evaporator and glassware chiller and vacuum pump and controller but there are also a number of accessories that can help optimize your processA cold trap is designed to condense all vapors bar permanent gases into solid or liquid form.
