On/Off valve function with septum in a single unit is economical.
Lightweight, making it easier to carry in the field and reduces shipping costs.
Made of inert polypropylene to ensure purity of sample and non-contamination.
Push/Pull (On/Off) valve stem for quick, easy opening and closing of valve (< 1 second).
Faster than "twist action" valves.
Quick locking function, in closed position. Locked position is easy to verify visually, and prevents accidental sample loss during shipment
Virtually impossible to open or close valve too far
Valve Stem is 3/16" diameter
Fluoropolymer faced septum, with Ultra-low bleed silicone, prevents contamination and is located in base flange of valve with bag film below, so septum does not come into contact with sample inside bag.
Septum allows repeated punctures with syringes without leakage
