Who would have thought? This solvent-recovery unit turned out to be the perfect fix.
In September 2019, Auwii’s Solvent-Recovery Instrument played a decisive role in a Fortune-500 company’s tea-water-extract assay. Its arrival not only kept the project on track but also shielded neighbouring equipment from damage, quietly extending service life and saving the firm real money—a rare win-win for everyone involved.

Tea-water-extract determination in a nutshell
Boiling water is refluxed through tea leaves to dissolve water-soluble compounds. After filtration, rinsing, drying and weighing the spent leaves, the percentage of extractives is calculated. The higher the caffeine, purine alkaloids and phenolics liberated, the better the tea quality—so the test is a key quality indicator.
Two headaches were crippling the lab
The reflux step generates copious steam that slows the protocol and must be removed.
Hooking the rig to a house-vacuum pump protects the glassware, but the pump ingests the same steam and fails every few months—an expensive, recurring headache.
When the team discovered Auwii’s Solvent-Recovery Unit, interest was immediate. Designed as an innovative condenser for organic-solvent vapours, it couples to parallel evaporators, rotary evaporators, vacuum ovens, centrifugal concentrators, vacuum filters and SPE manifolds. It condenses and collects solvent vapours, or scrubs the exhaust from vacuum pumps, cutting VOC emissions and protecting personnel.
Key performance highlights
Triple-stage internal condenser traps >99 % of ethanol and >98 % of dichloromethane—far superior to conventional chillers or cold traps.
No cooling fluid, no external glass condensers, no fragile glassware, no spaghetti tubing—just a cleaner, safer bench.
All wetted parts are PEEK, PTFE or borosilicate glass; the unit shrugs off HCl and other aggressive media.
In the end, the customer gave Auwii’s solvent-recovery platform top marks. We thank them for the trust and will keep delivering focused, practical innovation for every lab we serve.
