Vials, Septa

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 and headspace seals ND20 are made of aluminium and are supplied with fitted septa made of a variety of materials. There are the following different types of caps available:

Plain caps with a 10 mm center hole. These caps are suitable for standard applications. They are available in several colours on request.

Clear lacquered caps, so called headspace caps, with a special score line that breaks when the internal pressure reaches 3.0 ± 0.5 bar. The excess pressure is then released, and the risk of the vial exploding can be avoided.

Clear lacquered centre tear-off caps and complete tear-off caps. These caps are available in several colours on request.

Gold lacquered, magnetic crimp caps with 5 mm centre hole to be used with CE HS500/HS800, CTC 500, as well as Fisons HS500 / HS800 instruments.

Gold lacquered, magnetic crimp caps with 8 mm centre hole to be used with CTC Combi PAL instruments.

Red lacquered, magnetic bimetal crimp caps with 8 mm centre hole to be used with CTC Combi PAL instruments.

These grey septa are temperature-resistant from -40 °C to 120 °C and have excellent chemical properties. They are 3.0 mm thick and have a hardness of 50° shore A.

Also on Pharma-Fix seals, it is only the butyl areas that can come into contact with the sample, and these are PTFE coated. The areas that abut the edges of the glass are not coated. This ensures a particularly good seal.

Snap ring seals ND11 are made of PE and are supplied with fitted septa made of a variety of materials. They are available in a soft and hard version as well as in different colours. Snap ring seals are very easy to use, time-saving and inexpensive.

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 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.

These septa are temperature-resistant from -40 °C to 120 °C and have excellent chemical properties.

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.

Screw seals ND15 are made of PP and are supplied without or with fitted septa made of a variety of materials. They have a 15-425 thread, a 9 mm centre hole or are closed.

Screw seals ND18 are made of PP and are supplied with or without fitted septa made of a variety of materials. They have a 18-400 thread, a 12 mm centre hole or are closed.

ND15 seals are suitable for items 7.616 898, 7.618 935, 7.616 655 and 7.618 936.
ND18 seals are suitable for items 7.616 899 and 7.616 139.

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

These septa are temperature-resistant from -40 °C to 120 °C and have excellent chemical properties.

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

Screw seals ND8 are made of PP and are supplied without or with fitted septa made of a variety of materials. They have a 8-425 thread, a 5.5 mm centre hole or are closed.

Suitable septa with a diameter of 8 mm made of different materials are available on request.

Screw seals ND24 (EPA) are made of PP and are supplied with or without fitted septa made of a variety of materials. They have a 24-400 thread, a 15 mm centre hole or are closed.

These septa are temperature-resistant from -40 °C to 120 °C and have excellent chemical properties.

With Ultrabond seals, the caps and septa form an inseparable unit, which means that even a blunt needle is unable to push the septa into the vial.
