Air Inlet Evaporation Control Valve, 1/4-28 PTFE with 6 month Reminder Timer (ALW-Air-Valve)

Air Inlet Evaporation Control Valve, 1/4-28 PTFE with 6 month Reminder Timer.

Air Inlet filter with integrated PTFE membrane allows air into the bottle but captures dust and other contaminants to keep your solvent delivery system clean.

• 1-way valve blocks solvent fumes from escaping
• Fits 1/4-28 UNF holes on standard port caps
• Time strip turns red after 6 months to indicate you should order a replacement filter

Includes an activate time strip so the end user can indicate the starting date and ensure a consistent replacement schedule. Simply press the "on" button when you install the filter to start the 6 month countdown.

*Please note that the time strip is a visual reminder based on time rather than saturation, based on a typical usage of 1mL/min, 5 days per week, 8 hours per day under typical lab conditions of 20°C. If your own usage is higher or lower than average, please devise your own replacement schedule accordingly.
