Vials, Septa

The shell vials made of clear or amber first hydrolytic class glass come in a set with transparent PE plugs. The star-shaped diaphragm in the plug facilitates easy penetration.

Shell vials made of plastic are a shatter-proof alternative to glass vials. They also come with a PE plug.

This easy-to-use, inexpensive vial/plug combination is suitable for non-critical analyses, especially in the field of HPLC.

Snap cap vials ND18/ND22 are made of clear third hydrolytic class glass. They are easy to handle and can be opened and sealed very quickly. Transparent PE caps have to be ordered separately.

Screw seals ND13 are made of PP and have a 13-425 thread. They have a 8.5 mm centre hole or are closed. Screw seals are supplied with fitted septa made of a variety of materials or without any septa.

Suitable septa with a diameter of 12 mm made of different materials are available on request.

Screw neck vials ND10 with 10-425 thread facilitate easy filling with viscous substances thanks to their wide opening. The vials are available in clear and amber first hydrolytic class glass.

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 -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.

Precision thread screw seals ND18 are made of metal and supplied with fitted septa made of a variety of materials. The hole size is selected so that the cap is suitable both for SPME and headspace applications. However, enough surface is left for the magnet to be able to transport a completely filled vial. The screw-on mechanism ensures that the cap always has a flat surface so that the bottle cannot fall from the magnet. Separation of the vial and cap for disposal after analysis is much easier than with crimp caps.

Closed caps in combination with precision thread screw vials ND18 are ideal for sample storage.

Precision thread screw seals are not suitable for item 7.616 139 !

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.

The short thread vials ND9 SureStop are available in clear and amber first hydrolytic class glass and are the best available on the market in terms of seal tightness and reliability. The vials have an additional stopper ring at the end of the thread which clearly marks the end point in the screwing-in process. This ensures that the tightness of the seal is independent of the touch or feel of the user screwing the stopper in. This ensures the lowest possible number of standard deviations and high reproducibility of analysis results.

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 have excellent chemical properties.

Septa with a double-sided PTFE coating show a very low particle formation during penetration.

These septa with instrument manufacturer's quality are temperature-resistant from -40 °C to 110 °C. They are easier to penetrate and have lower particle formation than septa made of natural rubber.

The screw cap 7.622 166 for bottle 7.622 167 has to be ordered separately.
