Factory Price Vacuum Controller for Rotary Evaporator
Product Description
VC-100C vacuum controller is widely used in the test and control of a vacuum system. During the process of evaporation, the negative pressure always down due to the saturation vapor and the micro-leak of the connections. To keep the negative pressure, users have to keep the vacuum pump working or control it manually. Which lead to a higher negative pressure or
fluctuation pressure in the system, and influence the evaporation and collection system:
1. Over-high negative pressure, material blasting boiling.
2. Over-high negative pressure, low temperature of the vapor, and low
rate of the collection
3. The corrosive gas will pollution and damage the vacuum pump.
4. The harmful gas will pollution the environment.
VC-100C vacuum controller can control the system vacuum, and solve these problems.
Features
1. Control, Set and display the system vacuum pressure.
2. With rapid response valve, which can close the gas circuit timely
and avoid the gas backflow in the pump to affect the system vacuum.
3. With noncontacting switch to control the vacuum pump and magnet
valve. No spark, safe and long useful life.HENNAN EFFISON TRADING CO., LTD
4. Main parts are made of stainless steel and PTFE, anti-corrosion.
5. With magnet valve, vacuum meter.
6. With filter flask and sugar flask to protect the equipment.

Considerations
1. Keep steady, no shaking
2. The extraction of gas with solid particles and dust is
Forbidden.
3. Be careful when moving the equipment.
4. Placed in ventilation, drying and non-pollution environment.
Installation
1. The vacuum controller shall be put steady and with no shaking.
2. Connect the controller with system.
Detailed Images
Supporting
When used with rotary evaporator and reactor:
1. Circulating coolant connected to the condenser (20℃ lower than the
vapor ).
2. System vacuum shall be same with the setting vacuum degree.
3. Heating
4. Stop heating and closed low temperature pump (Avoiding harmful gas
goes into vacuum controller and vacuum pump)
Operation
1. Connect the whole unit according to the picture. Turn on the vacuum
pump switch (The vacuum pump will controlled the vacuum controller).
2. When system vacuum pressure reaches the setting pressure, the
vacuum controller will automatic shut-off the magnet valve and vacuum
pump power at the same time.
3. When system vacuum pressure ups 0.5~1.0kPa, the vacuum pump and
magnet valve will work again (Automatic), until the vacuum pressure
back to the set point
