What’s the working principle of the rotary evaporator?

As a common evaporator in laboratory and production, rotary evaporator has been widely recognized for its excellent distillation and extraction performance.Today the staff of Lanphan will introduce the working principle and structural features of the rotary evaporator.I hope this article can help users make better use of our products. What’s the working principle of the […]

How can the rotary evaporator be used safely?

The use of a rotary evaporator is not only careful during the distillation process, but also during the operation.The modern rotary evaporator is not only the standard configuration of laboratory in medicine, chemical industry and biopharmaceutical industry, but also plays an important role in the processing of high-value samples. Due to the use of liquid and […]

What’s the operation procedure of the rotary evaporator?

rotary evaporator

Rotary evaporator is a necessary instrument for distillation and extraction in scientific research,the evaporation velocity depends on three conditions:vacuum, water temperature and cooling water temperature.Specifically, the main factor is that the higher degree of vacuum, the faster the evaporation rate, the vacuum degree (when the water evaporates) is ≥0.096 MPa; the second is that the […]

Rotor vane vacuum pump wear cause and repair method

Just as books wrinkle when they are read for a long time, sweaters pilling when they are worn for a long time, and shoes break when they are worn for a long time.Mechanical products are no exception,any mechanical product will wear out when it has been working for a long time.Let’s discuss with Lanphan about […]

Which domestic rotary evaporator is of good quality and cost-effective

We often use rotary evaporation instruments in chemical experiments. The quality of a rotary evaporator will have a certain impact on the efficiency of our work. If we use a poor quality rotary evaporator, and often have quality problems. Then, our work is in the process of repairing the rotary evaporator every day, wasting our […]
