Screw cap (bonded), N 9, PP,blue,hole,sil. beige/PTFE white, 1.3 mm

Description

Bonded screw caps N 9 with unslotted silicone/PTFE sealing washers are typical products for use on Waters autosamplers. Their thick and blunt needles tend to press mounted sealing disks into the bottles during penetration, which can be avoided by firmly fixing the sealing disk in the bonded closures. An additional slot prevents the formation of a vacuum inside the bottle during multiple injections. The septa are firmly attached to the cap and cannot be removed.
