Small rotary evaporatorAdopting a composite seal of polytetrafluoroethylene and rubber, it can maintain high vacuum degree, has a reasonable structure, and uses high-quality materials. The mechanical structure extensively uses stainless steel and aluminum alloy parts, and all glass parts are made of high-temperature resistant high boron glass. Mainly used for concentration, crystallization, drying, separation, and solvent recovery in the pharmaceutical, chemical, and biopharmaceutical industries. The principle is to heat at a constant temperature under vacuum conditions, causing the rotating bottle to rotate at a constant speed. The material forms a large film on the bottle wall and evaporates. The solvent vapor is cooled by a glass condenser and recovered in a collection bottle, greatly improving the evaporation efficiency. Specially suitable for the concentration and purification of biological products that are prone to decomposition and denaturation at high temperatures.
Small rotary evaporatorIt is actually a device for rapid concentration of liquid samples. The sample is heated, depressurized, and continuously rotated in a spherical glass container to increase the evaporation surface area and accelerate the evaporation rate. It is mainly used in biochemistry and molecular biology, so it is also widely used in laboratories. Suitable for reflux operations, rapid evaporation of large amounts of solvents, concentration of trace components, and reaction processes that require stirring. The small rotary evaporator system can be sealed and depressurized to 400-600 millimeters of mercury; Heat the solvent in the distillation flask with a heating bath at a temperature close to the boiling point of the solvent; At the same time, it can also rotate at a speed of 50-160 revolutions per minute to form a thin film of solvent and increase the evaporation area.
Small rotary evaporatorIt is developed based on the principle of constant temperature heating and thin film evaporation under vacuum negative pressure conditions. It is often used in conjunction with water baths in practical experiments. Below is a detailed explanation for youSmall rotary evaporatorOperation guide for matching with water bath:
1. Please raise the sample bottle of the small rotary evaporator to the highest point.
2. Please place the water bath in the center position where the sample bottle of the small rotary evaporator moves up and down.
3. Please slowly lower the main unit of the small rotary evaporator.
4. Lower the height of the small rotary evaporator and place the sample bottle in the water bath. Refer to the capacity of the sample bottle and add water to the water bath. Don't add too much water, just add it to a position 2cm away from the edge of the pot. When there is insufficient water and water needs to be added, be careful not to pour it directly onto the sample bottle, but to slowly add it from the side. As it is a water bath, please do not use liquids other than tap water or distilled water.
5. After confirming that the power switch of the water bath and the main power switch of the small rotary evaporator are turned off, insert the power plug into the socket.
6. WillSmall rotary evaporatorLower the sample bottle to the lowest part.
