In September 2019, the solvent recovery instrument produced by Aowei Instruments (Tongzhou Weipu) played a vital role in the tea extract determination experiment process of a large enterprise, because the intervention of this solvent recovery instrument not only It has helped the entire experiment to proceed smoothly, and also protected other equipment involved in the experiment, prolonged its service life, and virtually helped the company save costs. This is a win-win cooperation with multiple objectives.
In September 2019, the solvent recovery instrument produced by Aowei Instruments (Tongzhou Weipu) played a vital role in the tea extract determination experiment process of a large enterprise, because the intervention of this solvent recovery instrument not only It has helped the entire experiment to proceed smoothly, and also protected other equipment involved in the experiment, prolonged its service life, and virtually helped the company save costs. This is a win-win cooperation with multiple objectives.
Speaking of the determination of tea water extract, the basic principle of this experiment is to extract water-soluble substances in tea leaves with boiling water reflux, and then filter, rinse, dry, and weigh the extracted tea residues to calculate the water extract content. The core significance is to detect some beneficial caffeine, purine base and some phenolic compounds in tea through this leaching experiment. The higher the content of these substances, the better the quality of the tea.

In this experiment, there are several points that bothered the whole experiment. One: because boiling water reflux was used to extract the water-soluble substances in the tea during the whole experiment, a large amount of water vapor would be generated in this process. Water vapor will seriously affect the process of the experiment, and you need to find a way to deal with it. Second: If you use a positive air pump for extraction, this will cause another problem, that is, the vacuum pump is often damaged due to the extraction of water vapor. Maintenance and replacement of the vacuum pump It is also not a small cost for enterprises.
Therefore, when the user of the enterprise learned about the solvent recovery instrument of Aowei (Tongzhou Weipu), it has a strong interest. This solvent recovery instrument is an innovative product for the collection of organic solvent vapor condensation. . Mainly used with laboratory parallel evaporator/concentrator, rotary evaporator, vacuum drying oven, vacuum centrifugal concentrator, vacuum filtration, solid phase extraction and other sample pretreatment equipment to condense and recover solvent vapor, or it can be connected with vacuum pump Use, purify the exhaust gas discharged from the vacuum pump, reduce the pollution of organic exhaust gas to the environment, and protect the health of the experimenters.
The equipment has a built-in three-stage condenser. Almost all solvent vapor is condensed and recovered. The recovery rate of ethanol is better than 99%, and the recovery rate of methylene chloride is better than 98%. Compared with traditional cooling circulating water machines and cold traps, it has a higher solvent Recycling efficiency is more green and environmentally friendly.

At the same time, the solvent recovery instrument does not need to add cooling circulating liquid, does not need to connect to the glass condenser, users no longer worry about the fragility of glass devices, and avoid the connection of complicated pipelines, which is more conducive to the cleanliness of the laboratory.
The equipment also has the characteristics of PEEK, PTFE, high borosilicate glass, which are in contact with gases and liquids, and can withstand hydrochloric acid and strong corrosive solvents, anti-corrosion and durability.

In the end, the enterprise user highly recognized the solvent recovery instrument product produced by Aowei (Tongzhou Weipu) and gave a very good evaluation. First of all, thank you very much for the user’s recognition of us. We will continue to maintain the spirit of concentration. The majority of users develop and manufacture better quality products.
