Because Per- and Polyfluoroalkyl substances don't break down they can accumulate over time in the environment and in the human body. There is increasing evidence that exposure to PFAS can adversely affect human health. As a result, regulatory bodies are increasingly legislating that many materials should be tested to ensure that they contain no traces of PFAS or that the traces are below allowed legal limits.

Because PFAS are widely used in materials, such as PTFE, commonly used in chemical analysis consumables, laboratories are in need of new labware products to minimise background contamination from these chemicals.

When you are unable to use PTFE as a liner – our new polyimide/silicone lined closure is the perfect alternative.  This new closure has a useable temperature range up to 130°C., while the liner performs well up to ten injections.
The polyimide is amber translucent and the white silicone rubber is a high purity rubber composition resulting in low leachables.

Use with our polypropylene vials, designed to work in most autosamplers.  These lightweight vials are an economical alternative to glass.  Manufactured from chemical resistant polypropylene, they are ideal for sampling, testing, storing and transporting.

Introducing our new and exclusive Digest-n vessels, providing a novel and unique approach to acid digestion.

The Digest n-Vessel is a high purity PFA semi-closed digestion vessel for the non-pressurised digestion of samples utilising a reflux method. The Digest n-Vessel is ideal for the trace elemental analysis of geological, environmental and biological samples with large sample weights and with a wide variety of acids.

Made from fully inert, high purity PFA, Digest-n Vessels can be used with any standard laboratory hotplate system and are an ideal alternative for the digestion of otherwise difficult samples. The vessel comprises a lower digestion section screwed on to an upper reflux section incorporating a condensing n-tube permitting the continuous refluxing of the digest acid.
