Vials, Septa
Screw neck vials ND24 (EPA)
Screw neck vials ND24 made of clear and amber first hydrolytic class glass are suitable for EPA (Environmental Protection Association) analysis and can, upon request, be supplied with a sterility certificate that is specifically required for TOC analyses.
These vials are especially used with autosamplers made by Agilent, Dionex, Shimadzu, Tekmar, Thermo Scientific and Varian....
With silicone / PTFE septa
Precision thread screw seals ND18 are made of metal and supplied with fitted septa made of a variety of materials. The hole size is selected so that the cap is suitable both for SPME and headspace applications. However, enough surface is left for the magnet to be able to transport a completely filled vial. The screw-on mechanism ensures that the cap always has a flat surface so that the bottle cannot fall from the magnet. Separation of the vial and cap for disposal after analysis is much easier than with crimp caps....
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 silicone / PTFE septa, EPA quality
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 -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 natural rubber / TEF septa
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.
These septa are temperature-resistant from -40 °C to 120 °C and ideal for multiple injections thanks to their excellent resealability properties....
Short thread vials and micro-vials ND9, SureStop
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....
With butyl / 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.
