The septa are especially designed for the screw caps with GL thread.

Snap ring vials and micro-vials ND11 made of clear and amber first hydrolytic class glass can be used on almost all autosamplers and can also be used on equipment with robotic handling.

As an alternative to snap ring seals, snap ring vials and micro-vials, ND11 can also be sealed with crimp seals ND11 since the two snap ring lips together have the same height as a crimp neck.

Vials with snap ring seal are only recommended for HPLC.

The LABSOLUTE® kits ND9 contain shrink-wrapped short thread vials ND9 made of clear or amber first hydrolytic class glass and corresponding short thread screw caps made of PP.

Kits containing Ultrabond seals are especially for the use with Waters autosamplers.

These ND18 screw caps with 18-400 thread are not compatible with ND18 precision thread vials !

These septa are temperature-resistant from -60 °C to 200 °C and have better purity than septa made of natural rubber or red rubber. However, they have less effective resealability properties and are therefore more suitable for single-injection applications.

Short thread vials and micro-vials ND9 are available in clear and amber first hydrolytic class glass and can be used on almost all autosamplers. You can replace other 1.5 ml vial types like 11 mm crimp neck vials, 8-425 and 10-425 screw neck vials, which can help rationalize stocks.

The wide opening requires matching micro-inserts with 6 mm diameter.

Due to the technical geometry, the vails can be used on all common autosamplers, but preferentially on instruments made by Agilent, HTA, Shimadzu, Thermo Scientific, Varian and Waters.
