This SiloniteTM coated vial and bottle liner allows for a vacuum tight seal when evacuating samples through the Entech Sorbent Pen for performing the VASE (Vacuum Assisted Sorbet Extraction) technique.
The Sorbent PenTM (Patent pending) Extraction System provides a convenient way to perform vial extractions using 30 position trays. Load the sample to be extracted into the vial, insert the Sorbent PenTM, provide a vacuum through the top of the Pen, and then close the cover. The Sorbent PenTM Extraction Unit agitates the samples to speed up transfer to the headspace, while heating the sample from ambient to as high as 65°C. Extractions will be complete in 1–48 hours depending on the application.
