Air valves Generation 2.0 for SafetyCaps
Maximum safety for HPLC solvent supply. The integrated air valve (B) blocks hazardous vapours and cleans the inflowing air (M) from dust and dirt particles.

• Protection against escaping solvent vapours
• Solvents (L) und and mixtures remain clean and stable
• No twisted tubing, easy container exchange
• No air intake in to the HPLC system
• Reproducible analytical results through stable mobile phase
• Use the supplied blind plugs to tighten connections which are temporarily inactive or not in use
• Air valve (B) with PTFE filter (G) and Luer-Lock adapter (A)
• Valve membrane (H) optimized for analytical and preparative flow rates
• Improved PFA fittings (C)
• Body (D / I) made of medical grade PTFE, food safe, FDA conform
• Screw cap (F) made of PPS, autoclavable / sterilisable up to 200 °C
• PTFE and PPS with excellent chemical resistance and flammability classification V-0 (UL-94)
• Insertion label (E) for individual inscription
• Improved FKM seal (J) for stable fit on any bottle
• Improved ergonomics and construction (K)
• Thread size UNF 1/4'' 28G
• Luer Lock adapter
• PTFE Filter

Valve membrane blocks vapours and opens at negative pressure
It is recommended to replace the valve every 6 months
