Working principle:
The evaporation flask rotates at a constant speed and the water bath is heated at a constant temperature. Under this condition: the material forms a large-area uniform thin film on the inner wall of the evaporation bottle for quick evaporation. The evaporation efficiency can be improved under vacuum conditions (a vacuum device needs to be connected). When the solvent vapor passes through the glass condenser coil, the vapor is cooled to a liquid ( a cooling device need to be connected) and recycled in a collection flask.
This series of products needs to be equipped with vacuum devices (circulating water type, rotary vane type, diaphragm type and other vacuum pumps), or cooling and circulating devices to form a system devices.
Features:
• The parts in contact with the material are all made of high borosilicate glass (expansion coefficient 3.3) and PTFE materials, which have stable performance and are not easy to react with the materials.
• The main stent is made of aluminum alloy.
• The sealing system uses PTFE + fluororubber compound sealing.
• The piston-type feeding valve is sleeved with PTFE extension tube, which can be continuously fed to the evaporation bottle under vacuum status.
• Upright double-layer serpentine coil as integrated condenser.
• Rotating and heating is controlled by power switch, which is a ON-OFF tilt button.
• Electronic stepless speed regulation, fine-adjustment by knob, digital display of rotary speed.
• The bath is made of aluminum alloy + Teflon composite pot. And the heating plate is closed and heated with PT100 sensor and digital display of temperature.
• The main machine is lifted electrically, and the manual switch, a tilt button also can control the up and down of main machine.
• Rotating and heating double fuses safety protection.
