We make your Lab a safer Place!

The SCAT ventilation valve enables controlled, filtered pressure equalization in hermetically sealed eluent and solvent containers in HPLC laboratories. When solvent is withdrawn by the HPLC and negative pressure develops, the valve opens reliably and allows filtered air to enter. This supports consistent liquid flow, stable process conditions and reproducible analytical results. At the same time, the valve helps reduce solvent vapors and contributes to safer working conditions in the laboratory. Recommended service life: 6 months.

Details

The SCAT Europe vent valve (Art. 317010) provides emission-free pressure compensation on HPLC/UHPLC supply bottles. Its UNF 1/4"-28 thread screws directly into the SCAT Safety Cap. As the HPLC draws eluent from the hermetically sealed bottle, a vacuum builds up. The vent valve equalizes this pressure exclusively toward the inside of the container, so no solvent vapors can escape. An integrated PTFE filter retains the finest particles from the ambient air and reliably protects the eluent from contamination. Because the filter gradually clogs, SCAT recommends replacing it every six months. Over this period, a single vent valve prevents the evaporation of up to 750 ml of solvent per bottle. You can track the replacement date with your own note or the included Timestrip indicator. For advanced applications, the Luer lock adapter allows you to sparge the eluent or dehumidify the incoming air. The SCAT vent valve enables safe, emission-free pressure compensation – for greater workplace safety and reproducible HPLC results.
