Rotary Evaporator

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. The process of rotary evaporation is most often used to separate solvents with low boiling points, such a n-hexane or ethyl acetate, from compounds which are solid at room temperature and pressure.

Vacuum Pump

Vacuum Pump

A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial vacuum.The pump is suitable for the research experiment, small scale test and small scale production process which have the processes such as evaporation, distillation,crystallization, drying, sublimation, filtration and decompression, degassing.

Circulating Pump

Circulating Pump

High and low temperature circulating device can provide constant temperature for chemical experiment.It includestwo systems: cooling system and heating system. These two systems can work together or independently.It is often combined with jacketed glass reactor or jacketed vessel, widely used in medical, chemical and biological industries

Lab Reactor

Lab Reactor

Jacketed glass reactor is widely used in the experiment, middle-scale test, and production of chemistry, fine chemical engineering, biological pharmacy and synthesis of new materials. The reactor can be a system with circulating water vacuum pump, diaphragm vacuum pump,chiller / low temperaturecirculator, heating and high and low temperature circulating device.

Magnetic Stirrer

Magnetic Stirrer

Magnetic stirrer is used for liquid mixture of laboratory instruments, mainly used for mixing or heating and mixing of low viscosity liquid or solid-liquid mixture.Cooperate with heating temperature control system, can according to the requirements of the specific experiments heating and temperature control sample, temperature conditions necessary to sustain the experimental conditions, ensure liquid mixed experimental requirements.
