Product Description

Product introduction
Rotary evaporator series products are mainly used for testing, research and development and production in the pharmaceutical, chemical, biological products and other industries. This product is used in the vacuum negative pressure condition, using the principle of constant temperature heating and thin film evaporation to evaporate, concentrate, crystallize, dry, separate, and recover the solvent. The parts in contact with the material are all high temperature resistant and corrosion resistant. The borosilicate glass and polytetrafluoroethylene materials are especially suitable for the concentration and purification of biological products which are easily decomposed and denatured, and are not easy to react with various materials.

Working principle:

Under the condition of vacuum negative pressure, the rotating bottle is rotated at a constant speed by using the speed-regulating knob. The material forms a large-area uniform film on the bottle wall, and the material in the rotating bottle is uniformly heated by the intelligent constant-temperature water (oil) bath. After evaporation, the generated solvent vapor is rapidly cooled by the cooling coil of the glass condenser and recovered in the collection bottle.

The main capacity of the rotary evaporator produced by our factory is 1-2L, 3L, 5L, 10L, 20L, 30L, 50L, 100L. Each type of capacity has different grades for customers to choose. This product can be used with the vacuum pump to improve the evaporation efficiency (required); it can be used together with the low-temperature coolant circulating pump to improve the recycling efficiency. Please purchase the matching equipment as appropriate.

• The main body bracket is made of anti-corrosion spray + aluminum alloy. The structure is reasonable and the materials are exquisite.
• The pot is made of high quality stainless steel for durability and durability.
• The sealing system is sealed with a combination of Teflon and imported fluoro rubber to maintain a high vacuum.
• All glass components are made of borosilicate glass (GG-17), which is resistant to high temperatures and corrosion.
• The angle of the nose is adjustable (to ensure that the condenser is vertical).
• The low-speed booster motor is used, and the main engine automatically moves up and down.
• Seesaw power switch control.
• Temperature digital display, intelligent constant temperature control, Cu50 sensor for fast and accurate temperature transfer.
• Electronic stepless speed regulation (0-120rpm), twist setting, easy to operate.
• Fuse safety protection.
• Upright double-layer serpentine coil condenser for high recovery.
• It can be continuously fed for customer’s convenience. The valve type feeding tube is sleeved with PTFE tube and water retaining ring.
