What are the unique features of the laboratory vacuum pumping unit?
Vacuum filtration is a widely used technique in various industries, and the final effect is to separate solid and liquid from specific liquids. For laboratory users, the application of this technology is also very extensive, but many customers may not buy the products that are not used in the laboratory due to the lack of relevant professional knowledge, or the purchase model is incorrect, so that the purpose of filtering cannot be achieved. . The following is a brief analysis of the characteristics of vacuum filtration in laboratory solid-liquid separation:
Microfiltration unit with a diameter of 25mm filter can be used
1. Small amount of filtration: Vacuum filtration for experimental purposes generally requires a small amount of sampled sample, which is much smaller than the single filtration requirement of tens of liters in industrial production. . In general, the laboratory's conventional suction filtration device, such as FS3310, is equipped with a 1000ml liquid collection bottle and a 300ml filter funnel. This specification meets almost all laboratory requirements. In addition, there are some experiments. Because the sample volume is very small or the value of the sample is very high, a smaller filter and filter are needed to reduce the loss in the sample re-filtration and the residue on the filter bottle. FS300M type micro vacuum filtration device.
One-piece vacuum filter - VF204A, greatly saving desktop professional space
2. Dimensions and noise requirements: Because it is not industrial production, the space in the laboratory is generally limited. Vacuum suction devices generally need to be placed on the desktop of the laboratory. If the size is too large, it will occupy too many laboratories. Space is even inconvenient to use. Laboratory-specific models such as the VF204A use an original one-piece construction that combines all the firmware and accessories required for general vacuum filtration, such as suction pumps, suction filters, suction funnels, vacuum gauges, regulators, and buffer cups. And the filter elements are all assembled in one body. Significantly reduced the space occupied by the countertop. In addition, due to the small laboratory space, the noise control requirements are generally high, and the maximum noise value of the VF204A does not exceed 50 decibels.
3. Different experiments require different structural requirements for the suction filtration device, because the purpose of filtration filtration in the laboratory is different, including medium sterilization filtration, microbial limit inspection filtration, mobile phase filtration, suspended solids filtration, cleanliness detection. Filter and so on. Each specific application will be different, such as medium sterilization filtration and chromatographic mobile phase filtration. Generally, the filtered filtrate needs to be directly loaded into the blue cap reagent bottle for subsequent storage and use. The funnel section of the R300-500 laboratory vacuum filter is specially designed to match the blue cap reagent bottle with a GL45 threaded port for easy connection of the funnel and the blue cap reagent bottle, allowing the filtrate to flow directly into the reagent bottle.

Vegetable fruit and vegetable extracts are plant active ingredients extracted from fruits and vegetables and they can be used in the food, nutraceutical and pharmaceutical industries. Fruit and vegetable extracts can be divided into the following categories.
1. Antioxidant fruit and vegetable extracts: Antioxidant fruit and vegetable extracts mainly contain vitamin C, vitamin E, carotenoids, etc. They can effectively resist damage by free radicals and have good health effects on delaying aging, anti-cancer and anti-inflammatory.
2. Antibacterial fruit and vegetable extracts: Antibacterial fruit and vegetable extracts contain a variety of active ingredients, such as rutin, citric acid, ascorbic acid, etc. They can inhibit the growth of bacteria and effectively prevent bacterial infections.
3. Anti-viral fruit and vegetable extracts: Anti-viral fruit and vegetable extracts contain a variety of anti-viral ingredients, such as anti-viral proteins, anti-viral peptides, etc., which can effectively inhibit the replication of viruses and effectively defend against viral infections.
4. Lipid-lowering fruit and vegetable extracts: Lipid-lowering fruit and vegetable extracts contain a variety of active ingredients, such as antioxidants, vitamins, minerals, etc. They can effectively lower blood cholesterol and triglycerides, which help prevent the occurrence of cardiovascular diseases.
