How to use explosion-proof rotary evaporator and when to use it

The use method of explosion-proof rotary evaporator and the precautions when using it:

     How to use explosion-proof rotary evaporator:

   1. Adjust the height of the explosion-proof rotary evaporator: manually lift, turn the hand wheel on the machine column, turn it forward to rise, and reverse to fall.

  Electric lift, touch the up button, the host rises, touch the down button, the host falls.

2. There are two external joints on the explosion-proof rotary evaporator condenser for cooling water, one end is connected to water, the other end is connected to water, generally tap water, the lower the temperature of the condensed water, the better. The upper port is installed to vacuum The connector is used for vacuum pumping.

3. Before starting the explosion-proof rotary evaporator, turn the speed control knob to the left to small, press the power switch and the indicator light is on, and then slowly turn to the right to the required speed. Generally, large evaporating flasks are used for medium, low speed, and high viscosity solutions. Use a lower speed. The flask is a standard interface No. 24, and it comes with 500ml and 1000ml two flasks. The amount of solution is generally not more than 50%.

   Notes for explosion-proof rotary evaporator:

  1. The glass parts of the explosion-proof rotary evaporator should be handled gently, and they should be washed, dried or dried before installation.

  2. Before installing the explosion-proof rotary evaporator, it is necessary to apply a layer of vacuum grease to the ground, the sealing surface, the sealing ring and the joint.

  3. Water must be added before the heating tank of the explosion-proof rotary evaporator is energized, and it is not allowed to dry without water.

  4. For the explosion-proof rotary evaporator RE-52B, (19) must be screwed into the fuse hole to prevent damage to the flask.

   5. Check if the explosion-proof rotary evaporator cannot be vacuumed up

  ①Whether the joints and interfaces are sealed

  ②Whether the sealing ring and the sealing surface are effective

  ③Whether the vacuum grease between the spindle and the sealing ring is applied well

  ④Whether the vacuum pump and its hose are leaking

  ⑤Are there cracks, cracks, or damage to the glass
