Adaptors, Luer, Vacuum, Stopcock

Adapter has an outer luer joint that provides a convenient way to connect solid phase extraction (SPE) cartridges, tubes or syringes to a standard taper inner joint. The adapter provides for easier sample concentration and clean-up while reducing the chances of cross-contamination. The addition of a 2mm PTFE stopcock between the outer luer joint and standard taper inner permits control of the vacuum source. Hose connection is 10mm OD at the largest serration.
