In April 2020, Aowei Instruments Green Lab series products (solvent safety bottle caps, intubation type waste collection, funnel type waste collection) received good sales news one after another. Among them, a teacher from a laboratory in Sichuan found us and thought To solve the problem of waste water collection during the use of its solid phase extraction equipment, it was precisely because of the green laboratory products of Aowei Instruments, that we immediately contacted us.

The solid phase extraction instrument is a device that uses solid phase extraction technology to work. Solid-Phase Extraction (SPE) is a sample pretreatment technology developed in recent years. It is developed from the fusion of liquid-solid extraction and column liquid chromatography. It is mainly used for sample separation, purification and concentration. Phase extraction is a physical extraction process that includes liquid and solid phases.

Its working principle is that the adsorption force of the solid to the analyte is greater than that of the liquid. When the liquid sample passes through the solid phase extraction column, the analyte is adsorbed on the solid phase surface, and other sample components pass through the column. The analyte is eluted with an appropriate solvent to achieve separation and enrichment from the sample matrix and interfering compounds.

Because of its working principle, waste liquid will also be generated during the working process of the solid phase extraction instrument, and these waste liquids are mostly waste water, organic solvents and chlorinated solvents. Before this, the teacher has been using ordinary Reagent bottles are used to collect these waste water. The element chlorine is very active and toxic. After volatilization, it is accompanied by a strong pungent odor, which will cause harm to the human body over time. Find us hoping to solve their problems.

This teacher chose our intubation type waste liquid collection device, because there will be multiple waste liquid discharge pipes from their instrument, and the intubation type waste liquid collection device has very rich interfaces, which can support a variety of hoses and hard tubes. , And its equipped exhaust gas filter can perform high-efficiency adsorption and filtration of exhaust gas, and the time label can record the time of use to remind users to replace it, and the PVDF material float switch on the device can perform liquid level detection to prevent too much waste liquid from overflowing. This product just solved the teacher's urgent need.
