Vials, Septa

Screw neck vials ND15 and ND18 made of clear and amber first hydrolytic class glass in combination with the corresponding screw caps are highly suitable as sample storage vials.

Screw neck vials ND15 have a 15-425 thread. ND18 vials have a 18-400 thread.

Item 7.616 139 is also suitable for headspace analysis (Perkin Elmer).

Crimp seals ND11 are made of aluminium. They are clear or lacquered in different colours and have a 5.5 mm hole. They are supplied with fitted septa made of a variety of materials.

These septa are temperature-resistant from -40 °C to 120 °C and ideal for multiple injections thanks to their excellent resealability properties.

Septa made of natural rubber / butyl / TEF combine the good physical properties of natural rubber (resealability) and the good chemical properties of butyl (analytical cleanliness).

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.

The transparent PE caps fit perfectly to the snap cap vials ND18 / ND22 / ND28.

Crimp neck vials and micro-vials ND11 made of clear and amber first hydrolytic class glass are used as standard in GC and HPLC. A large selection of micro-inserts is available for these vials.

Short thread screw seals ND9 are made of PP and are supplied with fitted septa made of a variety of materials. They have a 6 mm centre hole and are available in different colours. The screw caps are similar in shape to the crimp caps and are therefore also suitable for robotic handling.

These septa are temperature-resistant from -60 °C to 200 °C and have better purity than septa made of natural rubber, butyl or red rubber. However, they have less effective resealability properties and are therefore more suitable for single-injection applications. Septa with a double-sided PTFE coating show a very low particle formation during penetration.

Screw neck vials and micro-vials ND8 are available in clear and amber first hydrolytic class glass. They have a 8-425 thread and are used as standard in GC and HPLC applications. A large selection of micro-inserts with a 5 mm diameter is available for these vials. The micro-vials often require an adapter so that they can be used in an autosampler.

These vials are especially used with autosamplers made by Beckman, Shimadzu, Spark, Varian and VWR/Hitachi.

Short thread screw seals ND9 are made of PP and are supplied with fitted septa made of a variety of materials. They have a 6 mm centre hole and are available in different colours. The screw caps are similar in shape to the crimp caps and are therefore also suitable for robotic handling.

Screw seals ND10 are made of PP and have a 10-425 thread. They have a 7 mm centre hole or are closed. Screw seals are supplied with fitted septa made of a variety of materials or without any septa.

These septa are temperature-resistant from -40 °C to 120 °C and ideal for multiple injections thanks to their excellent resealability properties.

Short thread screw seals ND9 are made of PP and are supplied with fitted septa made of a variety of materials. The caps have a 6 mm centre hole and are available in different colours. The screw caps are similar in shape to the crimp caps and are therefore also suitable for robotic handling.

In this case, caps and septa form an inseparable unit (Ultrabond), which means that even a blunt needle is unable to push the septa into the vial.

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

Screw neck vials ND24 made of clear and amber first hydrolytic class glass are suitable for EPA (Environmental Protection Association) analysis and can, upon request, be supplied with a sterility certificate that is specifically required for TOC analyses.

These vials are especially used with autosamplers made by Agilent, Dionex, Shimadzu, Tekmar, Thermo Scientific and Varian.

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.

Screw seals ND10 are made of PP and have a 10-425 thread. They have a 7 mm centre hole or are closed. Screw seals are supplied with fitted septa made of a variety of materials or without any septa.
