The Solvent Recovery Unit developed by Auwii plays a vital role in the determination of tea leachate in a large enterprise start Sep., because of unit not only helps the whole process smoothly but also protects other equipment involved in the experiment, prolonging its service life and in addition helping the company save the costs. This is undoubtedly a win-win cooperation.

When it comes to the determination of tea leaching, the basic principle of this experiment is to extract the water-soluble substance in the tea leaves by boiling water, and then filter, rinse, dry, weigh the leached tea residue, and calculate the water leaching content. The core meaning is to detect some caffeine, purine base and some phenolic compounds in the tea by this leaching experiment. The higher the content of these substances, the better the quality of the tea.

During the experiment, several points that are plaguing the whole experiment. First, the water-soluble matter in the tea leaves needs to be extracted by boiling water, a large amount of water vapor is generated in the process, and it will seriously affect the progress of the experiment, another trouble is if a vacuum pump is used for the extraction process, it will damaged frequently by the extraction of the water vapor, maintenance Replacing the vacuum pump is also a big cost for the company.

Therefore,users are interested in Auwii Solvent Recovery Unit once they knew it, it’s an innovative product for organic solvent vapor condensation collection. Mainly combined with laboratory parallel evaporation/concentrator, rotary evaporator, vacuum drying oven, vacuum centrifugal concentrator, vacuum filtration, solid phase extraction and other sample pretreatment equipment, the solvent vapor is condensed and recovered, and can also be combined with vacuum pump, purify the exhaust gas discharged from the vacuum pump, reduce the pollution of the organic waste gas to the environment, and protect the health of the experimental personnel.

The equipment has a three-stage condenser, and almost all of the 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%. Higher solvent Recycling efficiency compared with the traditional chiller and cold trap.

At the same time, the solvent recovery unit no need to add cooling circulating liquid, and no need an external glass condenser. The user no longer has to worry about the fragile problem of the glass device, and also avoids the connection of complicated pipelines, which is more conducive to the clean and tidy laboratory.

The device also has a material that is in contact with gas and liquid. It is composed of PEEK, PTFE and borosilicate glass. It can withstand hydrochloric acid and strong corrosive solvents, and is corrosion-resistant and durable.

After a period time testing, users give a highly evaluation of the equipment. We would like to thank the users for their recognition. We will continue to maintain our spirit of concentration, develop and manufacture better products.
