Function Introduction
The Vacuum rotary evaporator distill apparatus is heated by water bath(oil bath) to form thin film under the negative pressure condition, evaporate highly, then condense and recycle the solvent simultaneously. The apparatus are particularly suitable for the heat-sensitivity material's condensation, crystallization, separation, recovery and so on. And reflux extraction can be avaliable for parts evaporator models. It is one of the necessary basic instruments in the chemical industry, pharmaceutical industry, universities and research laboratories and other units etc., while it is also the main means for producing concentrated extracts and analysis experiments.
1. Quick and easy lifting mechanism
RE201D, RE301 and RE501 rotary evaporators are water tank lifting. Turning the handwheel on the oil/water bath drives the bath to lift and go down. RE5299 is the motor thread lifting, that is, turning the handwheel on the screw stem will drive the rotating flask, rotating motor, condenser and collecting flask to lift or go down at the same time.
2. The evaporators can incline willfully along the horizontal direction within 0-45°
3. High evaporation rate vertical condensation system
The condenser adopts two structures. One is the dual pipeline convection principle and is used for evaporating organic solvents. The other is single pipe container with interlayer that could hold cooling water, ice and drikold. It is vertical type to decrease volume and is used for evaporating organic solvents.
4. Heating Tank
Stainless steel heating tube provides heat source. The temperature range will be RT~99 ℃ with water. The water tank is cylindrical and made of high quality stainless steel. So it is corrosion resistance and durable. The tanks are available for 2-20liter rotating flask heated. Moreover, the tank can be moved according the rotating flask size.
5. Vacuum Sealing
PTFE evaporating pipe, good sealing and heat-resisting. Joint part is sealed Fluorine rubber mat which brings good performance.
6. Automatic Temperature Control Digital Display
Temperature digital display and control by pt100 sensor. when the pre-selected temperature is reached the temperature you setted, the controller automatically will turn off the heater supply, When it is lower than the pre-selected temperature, controller will switch on automatically to realize constant temperature.
7. Rotating flask and Collection flask
The flasks are made of GG-17 high borosilicate glass which is blowed by hand. Their intensity, concentricity, glossiness, and surface finish are better than rough flasks.
