Air Inlet Evaporation Control Valve for Port Caps, 1/4-28 UNF, PTFE, with Reminder Timer

Air Inlet Evaporation Control Valve for 1/4-28 Port Caps: PTFE with Replacement Reminder Timer

This air inlet valve safeguards your solvent delivery system by combining solvent protection with a convenient replacement reminder. It fits standard 1/4-28 UNF ports on port caps.

As solvent is pumped from a closed bottle, air must enter to prevent a vacuum. This valve admits filtered air through a PTFE membrane while its one-way design reduces solvent evaporation.

Specifications:

• PTFE membrane filters incoming air
• One-way valve design reduces evaporation
• Fits standard 1/4-28 UNF port caps
• Built-in timer strip for filter replacement reminder
• Reminder timer based on typical usage: 1 mL/min, 5 days/week, 8 hours/day at 20°C

Compatible Port Caps
