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 When solvent is withdrawn by the HPLC and negative pressure develops, the valve opens reliably and allows filtered air to enter.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 "Air valve, UNF 1/4", PU=10"
The SCAT Europe vent valve (item 397010) provides emission-free pressure equalization in solvent supply bottles on the supply side of HPLC systems. It screws into a SCAT Safety Cap via a UNF 1/4"-28 connection, enabling fully hermetic operation.
As the HPLC draws in the eluent, negative pressure builds up inside the bottle. The vent valve compensates for this – venting takes place exclusively toward the inside, so that no toxic solvent vapors can escape. An integrated PTFE filter retains fine particles from the ambient air and protects the eluent from contamination.
This keeps occupational exposure limits in accordance with TRGS 900 reliably within range and keeps the eluent mixing ratios stable – the basis for reproducible analytical results. The Luer lock adapter also allows the eluent to be sparged or the air to be dehumidified.
Since every filter clogs over time, SCAT recommends replacement every 6 months. Over this period, a single valve prevents the evaporation of up to 750 ml of solvent. Packaging unit: 10 pieces.
The SCAT vent valve turns every supply bottle into a hermetically sealed, safe system – Safety First.
