Kimble® Kontes® Solid Phase Extraction Manifold Sets

These Kontes solid phase extraction manifolds are supplied with three-way valves that allow the venting to atmosphere of each station without affecting the vacuum in the rest of the system. It is manufactured from corrosion resistant Kontes® Stainless steel. Valves have Kontes® Stainless steel bodies with PTFE plugs. The SPE Funnels have a sharp edge on the bottom inside diameter that, combined with the stronger spring in our aluminum clamps, minimizes any horizontal capillary action of the sample and solvent into the disk. Extracted samples can be collected directly into K-D concentrator tubes, EPA water analysis vials, sample vials and test tubes. PTFE-coated Kontes® Stainless steel support screen reduces the possibility of sample-to-sample cross contamination compared to the traditional glass frit. The PTFE coating also protects the support screen from corrosion caused by acid preserved samples. The SPE Support Bases have a specially designed internal surface that reduces dead volume and minimizes holdback of the extracted analyte.
