Per- and polyfluoroalkyl substances (PFAS) are highly persistent, bioaccumulative man-made compounds that for decades have been used in the manufacture of everyday items such as fire-fighting foams, non-stick cookware and water-resistant fabrics. Their now ubiquitous presence in the environment poses a significant human health and environmental hazard, the extent of which is only now being understood. As a consequence, the need for increasingly stringent testing and regulatory guidance has never been greater.
We're pleased to offer an extensive range of high quality reference materials, available as neat products or individual solutions, to assist with this vital and challenging work. Click here for a list of available reference materials.
We also offer a range of PTFE-free autosampler vials and caps, specifically designed for PFAS sampling, testing and storage. Click here for further information.
We are pleased to introduce our new graduated 40ml clear glass vials that are ideal for environmental and water sampling.
CONOSTAN®offers calibration and verification standards for the analysis of lubricant additives, new and in-service lubricants, petroleum products and organic fluids/materials.
CONOSTAN® is the world's leading manufacturer of Elements in Oil standards and related spectroscopy products. Conostan's industry leading position is derived from superior product chemistry, manufacturing technology, and blending techniques. Their products are used extensively in the calibration and operation of analytical instruments for the analysis of elements in oil and other organic fluids.
Whether Single Element Standards, Mixes, Standards for Flash Point, Viscosity, TAN & TBN, Particle Size we have everything you may require. We also provide Custom prepared Mixes to your specifications.

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 and without use of additives, they are ideal for PFAS 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.
