SPE Disk Glassware and Manifolds

Kontes SPE glassware and manifolds has been specially designed for use with solid phase extraction disks to give the highest possible recoveries of extracted analytes from drinking water, surface water and waste water samples.
All SPE 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
SPE manifolds are manufactured from corrosion-resistant stainless steel
Valves have stainless steel bodies with PTFE plugs
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 up to 30 mm OD x 100 mm high
PTFE-coated stainless steel support screen reduces the possibility of sample-to-sample cross-contamination compared to the traditional glass frit
PTFE coating also protects the support screen from corrosion caused by acid-preserved samples
SPE support bases with 40-35 outer Standard Taper joints have a specially designed internal surface that reduces dead volume and minimizes holdback of the extracted analyte
Glassware is manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
