AI Technical Summary

Technical Problem

When laboratory water is drawn from an ultrapure water system, the open-type water collection method leaves a gap between the water outlet and the beaker, allowing impurities and microorganisms from the air to enter the pure water, affecting its purity and failing to meet the high-purity experimental requirements.

Method used

A laboratory pure water storage device was designed. By moving the connecting pipe and the water funnel downward through the downward moving component, the upper end of the beaker is inserted into the groove of the circular tube, filling the blank space between the water outlet pipe and the beaker, thus preventing the pure water from coming into contact with air.

Benefits of technology

It effectively avoids contact between pure water and impurities and microorganisms in the air, improving the purity of pure water and meeting the needs of high-purity experiments.
