Vials, Septa

These kits correspond to the standard ND9 kits with regard to their setup (shrink-wrapped short thread vials ND9 made of clear or amber first hydrolytic class glass with corresponding short thread screw caps made of PP). But there is a batch-specific test certificate with HPLC and GC chromatographs for every kit available on request. Certified kits are delivered completely shrink-wrapped. This means additional safety for the end user.

Each batch of HPLC and GC certified kits is tested on 15 critical parameters. In a method corresponding as far as possible to real laboratory conditions, an HPLC/UV and GC/MS test of a vial and seal combination will be carried out.

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

The micro-inserts made of first hydrolytic class glass are suitable for

• Short thread vials ND9, with wide opening made of glass or plastic
• Screw neck vials ND10, with wide opening
• Crimp neck vials ND11, with wide opening
• Snap ring vials ND11, with wide opening
• Shell vials, with a nominal volume of 2 ml

The LABSOLUTE® kits ND8 contain shrink-wrapped screw vials ND8 with small opening made of clear or amber first hydrolytic class glass and corresponding screw caps made of PP. In some cases, caps are already pre-screwed on the vials.

• Many kits are especially adjusted for use with an autosampler of one defined manufacturer
• Kits with pre-screwed seals reduce the risk of sample contamination
• Kits with pre-assembled micro inserts are available on request

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 ND20 are made of white PP and supplied with fitted septa made of a variety of materials. They have a 20-400 thread and are closed.

Suitable for screw neck vial 7.663 432.

The LABSOLUTE® kits ND24 contain shrink-wrapped screw vials ND24 made of clear or amber first hydrolytic class glass and corresponding screw caps made of PP.

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.

Suitable septa with a diameter of 20 mm made of different materials are available on request.

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 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.

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 septa, made of silicone white / PTFE beige, are temperature-resistant from -60 °C to 200 °C. They are 3.2 mm thick and have a hardness of 45° shore A. They 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.

Due to their high cleanliness, they are especially used for critical and sensitive analysis.

These seals correspond to competitor HT liner!

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 ideal for multiple injections thanks to their excellent resealability properties.
