The Agilent 12- and 20-position extraction manifold features a variety of characteristics, including 12 or 20 positions for luer tip SPE cartridges, a simple tip design for easy use of stopcocks or disposable needle tips, a vacuum gauge with control and release valves for monitoring and adjustment of vacuum level, a choice of four racks to accommodate a variety of collection vessels, a three-point interlocking system to ensure proper orientation of racks and keying cartridge position to corresponding collection vessel, chemically resistant and non-contaminating construction of glass, polyethylene, polypropylene, and Delrin components, and individually controlled needle-tipped valves (stopcocks) for flow control of each position.
This document provides instructions for the Agilent Vac Elut 12 and 20 position extraction manifold, a device designed for solid phase extraction (SPE) procedures. The manifold features 12 or 20 positions for Luer tip SPE cartridges, a vacuum gauge with control valves, and a three-point interlocking system for rack alignment. It is constructed from chemically resistant materials including glass, polyethylene, polypropylene, and Delrin.
| Number of positions | 12- or 20-place positions |
|---|---|
| Compatible cartridges | Luer tip SPE cartridges |
| Construction materials | Glass, polyethylene, polypropylene, Delrin |
| Vacuum control | Vacuum gauge with control and release valves |
A typical solid phase extraction procedure consists of conditioning the column, loading the sample, washing off interferences, and eluting analytes.
Close the exit valve or turn off the vacuum pump, then slightly offset the white ball from its seat to release the vacuum.
Slide the ejector tool under the needle tip or stopcock valve and push it down gently to release it.
