Vials, Septa
With silicone / PTFE septa, Ultrabond
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.

Kits ND9, certified
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....
With natural rubber / TEF septa
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 -40 °C to 120 °C and are ideal for multiple injections thanks to their excellent resealability properties....
Kits ND8
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
With RedRubber / PTFE septa
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....
With natural rubber / TEF septa
Crimp seals ND8 are made of aluminium. They are plain lacquered with a 4 mm hole and 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....
With silicone / PTFE septa
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 -60 °C to 200 °C and have better purity than septa made of natural rubber, butyl or RedRubber. However, they have less effective resealability properties and are therefore more suitable for single-injection applications....
Glass
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.

The LABSOLUTE® kits ND11 contain shrink-wrapped crimp neck vials ND11 made of clear or amber first hydrolytic class glass and corresponding crimp caps made of clear lacquered aluminum with 5.5 mm centre hole.
Septa with a double-sided PTFE coating show a very low particle formation during penetration....
Septa, 20 mm
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....
Septa, 8 mm
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....
