Laboratory rotary evaporator

The laboratory rotary evaporator is an advanced piece of laboratory equipment widely used in the pharmaceutical, chemical, and biopharmaceutical industries. It is specifically designed for concentration, crystallization, drying, separation, and solvent recovery, and is capable of meeting the demands of high-efficiency experiments.

Under vacuum conditions, this equipment uses constant-temperature heating to rotate the rotary flask at a steady speed, causing the material to form a large-area film on the flask wall, thereby achieving rapid and efficient evaporation. Solvent vapor is cooled by a high-efficiency glass condenser and recovered into a collection flask, significantly improving evaporation efficiency. This feature makes it particularly suitable for the concentration and purification of heat-sensitive or easily decomposable bioproducts.

Our laboratory rotary evaporators can be integrated with a variety of equipment, including water-circulating vacuum pumps, diaphragm vacuum pumps, low-temperature circulating (vacuum) pumps, circulating coolers, thermostatic circulators, and low-temperature cooling liquid circulation pumps, to build efficient experimental systems that meet diverse experimental requirements.

• Stable construction with extensive use of stainless steel and aluminum alloy components.

• High-boron glass has a low coefficient of thermal expansion and is resistant to corrosion and high temperatures.

• Spiral condenser increases contact area and improves condensation efficiency.

• The composite seal, made of PTFE and rubber, maintains a high vacuum.

• The Teflon bath pot offers strong corrosion resistance and a long service life.

• Electric lifting: The rotating assembly, evaporation flask, condenser, and collection flask rise or lower simultaneously.
