Plant oil extraction method

Plant oil extraction such as essential oil distillation , clove oil extraction, fish oil extraction,curcuma oil extraction etc, is more and more popular welcomed by researchers, even for some home laboratory, simple distillation units such as 2L 5L glass short path distillation kit, are hotsaled as its cheap price and easy operation. In fact,for plant oil extraction , the oldest & most common method is alcohol extraction, which has excellent solubility in lower alcohols such as ethanol and isopropanol, and as all known, essential oil extraction is effective as long as the water content in the alcohol is small. But alcohol extraction is also not popular as use ethanol, as alcohole extraction require high pressure extraction condition. Compared with alcohol extraction, use ethanol is more health and safety, more easier to handing for researchers. Most important, extraction with ethanol will produce a full spectrum extract that contributes to the synergistic activity of plant oil to e...

What is wiped film evaporator?

Wiped film evaporator is a new type of high-efficiency evaporator which is through a rotary wiper to make a film, and has a high-speed flow, high heat transfer efficiency, short residence time (about 10~50S), and can be used for falling film evaporation under vacuum conditions. 1. Small vacuum pressure drop The vaporized gas of the material is sent from the heating surface to the external condenser, and there is a certain pressure difference. Compared with the general evaporator, the scraper-type thin film evaporator has a large gas traversing space, and the pressure inside the evaporator and inside the condenser are almost equal, so the pressure drop is small. 2. Low operating temperature The evaporation process of the wiped film evaporator can be maintained under a high vacuum degree. Due to the increase of vacuum degree, the corresponding boiling point of material is rapidly reduced, so that the operation can be carried out at a lower temperature to reduce the thermal decomposition...

How much does rotary evaporator cost?

Rotary evaporator has become the best choice for many customers because of its economical price, simple structure and easy operation. It is an ideal equipment for laboratory evaporation /concentration /removal solvent /alcohol recovery. We all want to buy a cheaper rotary evaporator, but many of the equipment that looks very similar from the picture is actually quite different. Let's take a look at what are the points we need to pay attention to when choosing a rotary evaporator? The rotary evaporators are similar, but the quality is different. It is embodied in: glass thickness, electronic component brand, gasket material, workmanship and experience of rotating and lifting parts. These will determine the service life of the rotary evaporator, the system vacuum degree, the corrosion resistance, and the evaporation efficiency,etc. In short, price is one aspect, quality and service are also very important. If you choose a complete set of rotary evaporator equipment, you must consid...
