Vials, Septa
Crimp neck and headspace vials ND20
Crimp neck and headspace vials ND20 with rounded or flat bottom made of clear and amber first hydrolytic class glass need to be able to withstand very high internal pressures and, as a result, their walls are generally 1.2 mm thick. The vials are available with a flat DIN crimp neck or with a bevelled neck (HS neck)....
Snap ring vials and micro-vials ND11, wide opening
Snap ring vials and micro-vials ND11 made of clear and amber first hydrolytic class glass can be used on almost all autosamplers and can also be used on equipment with robotic handling.
As an alternative to snap ring seals, snap ring vials and micro-vials, ND11 can also be sealed with crimp seals ND11 since the two snap ring lips together have the same height as a crimp neck....
With bromo-butyl / PTFE 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....
Screw neck vials ND13
Screw neck vials ND13 with 13-425 thread made of clear and amber first hydrolytic class glass facilitate easy filling with viscous substances thanks to their wide opening.
The LABSOLUTE® vials for optimised micro-sampling are the best solution for very small sample volumes....
With RedRubber / PTFE 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 110 °C. They are easier to penetrate and have lower particle formation than septa made of natural rubber....
With silicone / 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 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....
With RedRubber / PTFE septa
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 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....
Special seals for crimp neck ND8
The blue Push-On caps made of PE have a thinned penetration point, but no additional septum. They are an inexpensive alternative to crimp caps for non-critical applications.
The transparent PE caps are 9 x 5.9 mm and have a 4 mm centre hole.
Septa made of natural rubber are temperature-resistant from -40 °C to 120 °C and ideal for multiple injections thanks to their excellent resealability properties....
