The small rotary evaporatoradopts a simple vertical cooler, high product, small footprint, and the height of the vertical condenser is reduced.
The lifting operation of the body is very convenient. The lift handle can move up and down smoothly and lock securely. There is also an auxiliary extension on the upper part of the body to adjust the position of the buffer bottle or small sample bottle. It can extend and slide up and down 30cm from the opening part, and it is equipped with a backflow prevention joint to prevent backflow. When used in combination with the vacuum controller NVC type connection, the recovery efficiency of the rotary evaporator can be improved, and a chemically resistant full Teflon gasket can be selected for the recovery of low-boiling organic solvents.
The main components:
1. Rotate the motor to drive the evaporating flask containing the sample through the rotation of the motor;
2. Evaporation tube, the evaporation tube has two functions, firstly, it plays the role of the sample rotation support shaft, and secondly, through the evaporation tube, the vacuum system sucks the sample out;
3. The vacuum system is used to reduce the air pressure of the rotary evaporator system;
4. Fluid heating pot, usually water is used to heat the sample;
5. Condenser tube, use double serpentine condenser or other condensing agents such as dry ice and acetone to condense samples;
6. Condensate the sample collection bottle, and the sample enters the collection bottle after cooling.
Features of the small rotary evaporator:
1. The instrument is developed by applying the principle of constant temperature heating and thin film evaporation under the condition of vacuum negative pressure.
2. The instrument is controlled by an imported frequency converter, and the stepless speed regulation makes the glass rotating bottle rotate at a constant speed, and the material forms a large-area uniform film on the bottle wall, and then the rotating bottle is heated evenly by a controllable constant temperature water bath.
3. It evaporates at high speed under the condition of vacuuming the system, and the solvent vapor is cooled by the glass double condenser and recovered in the collection bottle. The instrument is also equipped with a feeding interface and a feeding mechanism, which is convenient for automatic and continuous operation during the evaporation process.
4. Since the instrument works under vacuum conditions, and all parts in contact with materials are made of high temperature resistant high borosilicate glass and PTFE materials.
5. Therefore, the small rotary evaporator is especially suitable for the concentration, crystallization, separation and solvent recovery of heat-sensitive materials and materials that are contaminated with stainless steel and other metal materials.
6. Large contact area, high evaporation efficiency, easy to use, low noise, reliable sealing, can handle easily foaming materials, and complete specifications. Various specifications have been formed, which is convenient for users with different needs to choose.
