lanphan The distillation is a kind of thermodynamic separation process. It can evaporate components with low boiling points by utilizing that the boiling point of each component in the mixed liquid or liquid-solid mixture is different, and then condense the material to separate the whole components. It is the combination of evaporation and condensation unit operations. … Read more

[ux_image id=”24553″ height=”71%” lightbox=”true” caption=”true” image_overlay=”rgba(0, 0, 0, 0)” image_hover=”fade-in” image_hover_alt=”zoom”] [gap] The distillation efficiency is a key performance of lab rotovap. It determines both the experiment efficiency and the product quality. One obvious truth is that the higher the distillation efficiency, the more samples can be distilled for the same solvent. So what are … Read more
An essential oil extractor refers to an apparatus for extracting essential oil and pure dew. There are mainly two types of essential oil extractors in terms of different materials, which are stainless steel essential oil extractors and glass essential oil extractors. But both of them extract pure dew and essential oil by steam distillation. Working … Read more
[ux_image id=”19729″ height=”60%” lightbox=”true” caption=”true” image_hover=”zoom” image_hover_alt=”zoom-long”] [gap] A rotary evaporator (rotovap or rotavap) is to a type of laboratory equipment for solvent evaporation under reduced pressure, which is mainly composed of a vacuum system, a heated water or oil bath, a condenser and a motor. All of them play an essential role in the … Read more
The freeze drying is a new type of drying technology based on the principle of sublimation. The material containing water is froze at low-temperature. Then the ice sublimes and turns vapor directly. Water is lost when the vapor exhausts so the material turns dry. Nowadays, the freeze drying technology has been well-received in a great … Read more
The rotary evaporator is an ideal instrument for laboratory distillation extraction, material crystallization and solvent separation. The basic working process can be described below. The rotating flask is heated thermostatically and can rotate at a constant speed. Then the material forms a large area of thin film on the inner surface of the flask. The … Read more
