20L Classic Rotary evaporator(rotovap), manual lifting water bath

RE-2002 20L Classic Rotary evaporator(rotovap), manual lifting, water bath

Description

• Rotary evaporators are mainly used for concentration, crystallization, drying, separation, and solvent recovery in industries, such as pharmaceuticals, chemicals, and bio-pharmaceuticals.
• The working principle is to heat the rotating flask at a constant temperature under vacuum conditions, making it rotate at a constant speed. The material forms a large area thin film on the inner wall and then evaporates quickly. The solvent vapor is cooled by glass condenser and recycled into a collection flask, greatly improving evaporation efficiency.
• It needs to be equipped with a vacuum device (circulating water type, rotary vane type, diaphragm type, etc. vacuum pump) and a cooling circulation device to form a system device.

Features

• All parts in contact with the material are made of high-grade silica glass (expansion coefficient 3.3) and polytetrafluoroethylene, which have stable performance and are not prone to chemical reactions with the material, making it easy and safe to use.
• The main bracket is made of cold plate anti-corrosion spray plastic + aluminum alloy material, which has strong anti-corrosion and anti-oxidation characteristics. The pot bladder is made of stainless steel, with compact structure, durability and beautiful appearance.
• The sealing system adopts polytetrafluoroethylene + fluor rubber compound sealing, which can maintain high vacuum.
• The vacuum pressure gauge displays real-time vacuum and the pointer displays.
• The piston-type feeding valve is connected to the PTFE extension tube, which can continuously feed the material to the evaporation bottle under vacuum, making it convenient for customers to use.
• Integrated condenser with upright double-layer serpentine coil ensures high recovery rate.
• Rotation and heating power switch control, tilt button (ON-OFF) for easy operation
• Electronic stepless speed regulation, fine adjustment by turning the knob, digital display of speed, simple and easy to operate.
• Digital display of constant temperature bath temperature, K-type sensor at the bottom of the pot + stainless steel probe, fast and accurate temperature transmission
• The water bath has a hand wheel for lifting and lowering, which is convenient for lifting and lowering.
• Rotating and heating double fuses with high safety protection performance
