I. INTRODUCTION

The Waters Extraction Manifold features:



Positions for up to twenty extraction cartridges.



Long needle tips which channel the cartridge effluents directly

into the corresponding collection vessels and eliminate immediate

fittings which could be a source of sample loss or cross-

contamination in other manifold designs.



Vacuum gauge, control and release valves for monitoring and

adjustment of vacuum level to control flow rate.



A choice of four racks to accommodate a variety of collection

vessels.



Three-point interlocking system to ensure proper orientation of

racks, keying cartridge position to corresponding collection vessel.



Chemically resistant, non-contaminating construction of glass,

polyethylene, polypropylene, and Delrin™ components.



Individually controlled, needle-tipped valves (stopcocks), available

as accessories, permit simultaneous processing of samples when

drying of traditional SPE cartridges must be avoided.
