The parts in contact with the materials are all made of high borosilicate glass (expansion coefficient 3.3) and polytetrafluoroethylene materials, which are stable in performance and difficult to chemically react with the materials.

The main body frame is made of cold plate anti-corrosion spray + aluminum alloy material, and the pot is made of 304 stainless steel.

The sealing system adopts PTFE + fluorine rubber compound combination seal.

Oil-based vacuum pressure gauge displays real-time vacuum and pointer display.

The piston-type feeding valve is sleeved with a polytetrafluoroethylene extension tube, which can continuously feed to the evaporation flask under vacuum.

Vertical double-layer serpentine coil double condenser, main cooling + secondary cooling double condenser. (EXR-1010)

Vertical serpentine coil double condenser, two-layer coil for main cooling and three-layer coil for sub-cooling. (EXR-1020)

Vertical three-layer serpentine coil condenser, main cooling + sub cooling double condenser. (EXR-1050)

Large LCD screen, simultaneously controls rotation, heating and lifting.

The rotating motor is a brushless deceleration booster motor with no sparks and low noise. (EXR-1010, EXR-1020)

The rotating motor is a brushless deceleration booster motor with no sparks and low noise; the lifting motor is also a deceleration booster motor. (EXR-1050)

Bath pot thermostatic control, pot bottom PT100 sensor + stainless steel probe.

The bath pot is electric lifted, and the bath pot is equipped with a silicone cover, which is heat-insulating and anti-scalding.

Rotating, heating double fuse safety protection.

The collection bottle has a lower discharge port and is connected with a glass + PTFE independent discharge valve.

The bottom of the pot is equipped with a water drain valve, which is convenient for draining liquid.

The vacuum switching valve can continuously collect and discharge materials without affecting the system vacuum and solution distillation.

Over-temperature safety protection function, when the actual temperature exceeds the set temperature by 5℃, the machine will automatically cut off the heating.

Anti-dry function, when the water level in the heating pot is lower than the heating tube, the machine will automatically power off.

If the machine is suddenly powered off during work, the machine will automatically stop heating when the power is turned on again.

The lifting motor is explosion-proof, the LCD control meter is explosion-proof, and the cable is through the explosion-proof tube.
