Supel™ Swift HLB is a polymeric stationary phase for solid phase extraction (SPE) prior to instrumental analysis. It has both hydrophilic and lipophilic functional groups for the extraction of a broad range of compounds from aqueous samples. It retains analytes having diff erent polarities and Log P values due to its hydrophilic and lipophilic balance (HLB) property.

Our Smart SPME fibers are equipped with a unique Smart chip that offers traceability, ease-of-use, and increased productivity. The smart SPME fibers are an extension of our expertise and innovation from traditional SPME coatings to smart SPME format for accurate, reliable, and consistent results.

The over coating of fibers is a new technology in fiber coating to protect the SPME fiber from matrix components. This allows for immersion of the fiber directly into complex samples ensuring a more efficient extraction (e.g. of semivolatile compounds). Polydimethylsiloxane (PDMS) is used to overcoat a PDMS/divinylbenzene (DVB) fiber. The resulting fiber is more physically robust and resistant to chemical fouling and allows f…

The nitinol-core of SPME fibers enhances the fiber performance and the precision of chromatographic results to enhance lot-to-lot and fiber-to-fiber reproducibility, increase fiber durability, and maintain selectivity and inertness compared to fused silica core fibers.

S-Pak ® sterile, individually packed, gridded membrane filters are made from mixed esters of cellulose and have been optimized for MF method microbiological analysis of water or other liquids.

GranuCult™ is our new brand name for our existing granulated dehydrated culture media which apply to new EN ISO 11133:2014 and various other ISO standards and FDA-BAM / USDA-FSIS methods for testing of food and water samples. All these media are currently being updated to be fully compliant to the latest version of these standards and regulations with respect to composition and quality control and will be available shortly.
