3L digital display multiple effect condenser rotary evaporator

RE-301 rotary evaporator is mainly used in the concentration, crystallization, drying, separation and solvent recovery of pharmaceutical, chemical and biological pharmaceutical industries. Its principle is: under vacuum condition, constant temperature heating makes the rotary bottle rotate at constant speed, and the material forms large area film on the bottle wall, so it can be evaporated efficiently. The solvent evaporation is cooled by the high-efficiency glass condenser and recovered in the collecting bottle, so as to greatly improve the evaporation efficiency. The utility model is especially suitable for concentrating and purifying biological articles with high temperature and easy decomposition and degeneration.

RE-301 rotary evaporator is an indispensable instrument for evaporation, concentration, crystallization, drying, separation and solvent recovery in the research and production of medicine, chemical and biological products. The rotary evaporator is developed under the condition of vacuum and negative pressure, using the principle of constant temperature heating and thin film evaporation. Rotary evaporator with stepless rotation of the glass bottle rotating at a constant speed, the material is formed large area uniform film on the bottle wall, then the intelligent thermostatic water bath for rotating the bottle uniformly heated at high speed under the condition of vacuum evaporation, solvent vapor by high performance glass condenser cooling, recycling in collecting bottle. Rotary evaporator is working under vacuum, and all material contact part adopts the high temperature resistant borosilicate glass and Teflon material, concentrated especially suitable for biological products of high temperature easy decomposition degeneration and purification. The factory set rotary evaporator essence of similar products at home and abroad, in successful practice, has formed 1L,2L, 5L, 10L, 20L, 30L,50L, 100L series, efficient and practical, follow the economic principles of product design, all for the sake of users.

RE-301 Rotary evaporator using procedures

1, vacuum: open the vacuum pump, vacuum not, should check whether the bottle mouth sealed, vacuum pump leaks, placed shaft sealing ring is intact, the external vacuum tube in a series of vacuum switch can improve the recovery rate and evaporation rate.

2, feeding: using the system vacuum negative pressure, liquid material can be in the feeding mouth with a hose inhalation rotating bottle, liquid material not more than half of the rotating bottle. The instrument can be continuous feeding, feeding should pay attention to: turn off the vacuum pump; stop heating; to evaporate after the stop, slowly open the pipe cock, in case of backflow.

3, heating: this instrument is equipped with a specially designed water bath pot, you must first add water after the electricity, temperature control scale 0-99 degrees, for reference. Due to the existence of thermal inertia, the actual water temperature is about 2 degrees higher than the set temperature. When used, the setting value can be corrected. For example, you need water temperature 1/3-1/2. Unplug the power plug after use.

4, rotation: open the electronic control box switch, adjust the twist to the appropriate evaporation speed. Attention to avoid boiling water, bath vibration fluctuation.

5. Turn on the cooling water.

6. Recovery solvent: turn off the vacuum pump, turn on the feed switch, deflate, and remove the solvent in the bottle

RE-301 Rotary evaporator maintenance

1, carefully check the instrument before, glass bottle is broken, the interface is consistent, pay attention to gently handle.

2, with soft cloth (can be used instead of paper napkin) wipe each interface, and then apply a little vacuum grease. After using vacuum grease to cover, to prevent dust entering.

3, the interface can not be twisted too tight, should be regularly loose, loose, to avoid long-term locking, causing the connector to bite.

4, first open the power switch, and then let the machine from slow to fast turn, stop when you want to stop the machine in the state, and then switch off.

5, all over the Teflon switch can not be too tight, easy to damage the glass.

6, every time after use must use all kinds of stains, soft cloth to wipe on the surface stains, solvent residual, keep clean.

7, after the stop, unscrew each Teflon switch, long-term static in the working state, will make the Teflon piston deformation.

8, regular cleaning of the sealing ring method is: remove the sealing ring, check whether the shaft product dirt, wipe clean with a soft cloth, then coated with a little vacuum grease, can be re installed, to keep the shaft and seal lubrication.

9, electrical parts must not enter the water, is strictly prohibited to damp.

10, must purchase the original authentic fittings, optional use of other parts of the machine will cause fatal damage.

11, the machine to do any repairs or inspection, we must first cut off the power supply, water. Indicating that this equipment is fragile, please use it carefully when you use it
