rotary evaporator 50l for sale
Rotary evaporators can be used to recover and evaporate organic solvents. It uses a motor to drive the retort to rotate. Since the still is constantly rotating, zeolite can be dispensed with without bumping. At the same time, due to the continuous rotation, the liquid is attached to the wall of the distiller, forming a liquid film, which increases the evaporation area and accelerates the evaporation rate.
Attention should be paid to the use of: during vacuum distillation, when the temperature is high and the vacuum degree is high, the liquid in the bottle may boil. At this point the vacuum should be lowered to allow for smooth distillation.
When the rotovap for sale is stopped, first stop heating, then stop vacuuming, and finally cut off the power supply and stop rotating. Structure: The distillation flask is an eggplant-shaped or round-bottomed flask with a standard grinding mouth interface. connected to the pump.
R-1050 rotary evaporator
The other opening of the reflux condenser is connected to a receiving flask with a grinding mouth for receiving the evaporated organic solvent. There is a three-way piston between the condenser tube and the decompression pump. When the system is connected to the atmosphere, the distillation flask and the liquid-contacting flask can be removed to transfer the solvent.
When the system is connected to the decompression pump, the system should be in a reduced state. pressure state. When in use, the pressure should be decompressed first, and then the motor should be turned on to rotate the distillation flask. When it is over, it should be stopped first and then vented to the atmosphere to prevent the distillation flask from falling off during rotation. As a heat source for distillation, it is often equipped with a corresponding constant temperature water tank.
Through electronic control, the flask is rotated at a constant speed at the most suitable speed to increase the evaporation area. The evaporating flask is under negative pressure by means of a vacuum pump. The evaporating flask is placed in a water bath for constant temperature heating while rotating, and the solution in the flask is heated, diffused and evaporated in the rotating flask under negative pressure. The rotary evaporator system can be hermetically decompressed to 400–600 mmHg.
Rotary evaporators lower the boiling point of the liquid by using a vacuum pump to reduce the pressure of the solution. As the liquid evaporates rapidly, it absorbs heat from the solution. This heat needs to be replaced so evaporation doesn't stop. The water bath below the rotating flask provides heat.
A sink is not a good replacement for a rotary evaporator, so the equivalent temperature doesn't make sense to me. Rotary evaporators are used because they do not need to boil the solution at high temperature, which prevents thermal damage to the sample. Rotary evaporators are suitable for reagent heating, matrix dissolution or cell culture cultivation, and the use of certain chemical reactions at high temperatures.
RE-5002 rotary evaporator
Technical characteristics of rotary evaporator:
1. Explosion-proof rotary evaporator-concentration-purification dryer automatic lifting type.
2. The choice is more diverse, including 3 different models of bathtubs, if you already own a bathtub, you can also adapt to the new models of the N-1200 series.
3. The F-glass assembly includes a condenser with protective film on the surface, a changeover port and a recovery bottle. The coating material of the present invention is a synthetic resin, which can prevent glass fragments from splashing, and has excellent chemical corrosion resistance and high transparency.
4. The newly developed Teflon gasket is equipped with good anti-corrosion and long-lasting performance, and can perform well even under high speed for a long time.
5. Using the one-touch interface, engage it with the spout of the cooling circulating water unit and take it out.
6. The unique design of this new V-type condenser can prevent the vapor condensate from flowing back to the sample bottle through the pipette; it can ensure that the analysis sample is not contaminated.
