An ethanol/dry ice slurry has a temperature greater than -800C. At atmospheric pressure the temperature of liquid nitrogen is -1960C. When dispensing dry ice exercise extreme care and transfer via provided gloves/mitts. ... High Vacuum Rotary Evaporation- BUCHI diaphragm or belt pump

Rotary evaporators are currently for sale with the favorable price and sincere service. A rotary evaporator (rotovap or rotatvap) refers to a kind of equipment for solvent evaporation under reduced pressure, which is composed of a vacuum system, a heated water or oil bath, a condenser and a motor that rotates the evaporation flask. As its name suggests, what is special is that the evaporation

The belt rotates a gear fixed onto the teflon rod which is seated in a 1 inner diameter bearing to keep it in place. ... The article that was posted above was a description of the very first rotary evaporator constructed, ... I plan on using a friedrich condenser but a dry

Rotary vane pumps can be categorized into belt-drive pumps and direct-drive pumps. The operating temperature of belt driven pumps is usually lower than direct-drive pumps and belt-drive pumps operate at a lower RPM (revolutions per minute). Note that belt drive pumps should always have a guard over the belt and movingcomponents to prevent injury

Rotary evaporators, commonly known as rotavapors, rotavaps or rotovaps, are extremely valuable to a number of downstream applications requiring efficient distillation & solvent removal. Often combined with a vacuum pump, rotary evaporators are used to remove solvents from samples through evaporation. During this process, rotary evaporators reduce the pressure within the system to lower the solvent

14. Ensure that there is solid dry ice visible in the trap at all times. Operation 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

Rugged chemical duty construction to resist harsh vapors. MPC PTFE dry vacuum pumps include essential features to ensure efficient rotary evaporation. With ultimate vacuum levels from 75 mbar (56 torr) to 1 mbar (0.75 torr), flow rates up to 138 l/min there is a pump for all rotary evaporator

A rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.. The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid)
