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 micro-inserts with polymer foot are not suitable for shell vials.

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.

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.

The choice of the right septa depends on the application. Many septa are PTFE coated on one side. PTFE is highly resistant against many chemicals and forms an inert border between the sample and the base material of the septa.

The septa's base material has various physical and chemical properties, like temperature resistance, resealability, cleanliness, hardness and thickness.

Natural rubber/TEF

• Temperature-resistant from -40 °C to 120 °C
• Excellent resealability properties
• Inexpensive for standard applications in the fields of GC and HPLC

RedRubber/PTFE

• Temperature-resistant from -30 °C to 110 °C
• Softer and therefore easier to penetrate than natural rubber
• Not as good resealability properties as natural rubber
• Higher chemical purity than natural rubber
• Inexpensive for standard applications in the fields of GC and HPLC

Butyl/PTFE

• Temperature-resistant from -40 °C to 120 °C
• Higher chemical purity than natural rubber and RedRubber

Silicone/PTFE

• Temperature-resistant from -60 °C to 200 °C
• More suitable for single-injection applications
• Much higher chemical purity than natural rubber and RedRubber
• Very low particle formation during penetration in case of double-sided PTFE coating
• Best for the thin and fragile needles of the autosampler
• Best for critical analysis (UltraClean quality)

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

Accessories Without septa

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 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!
