CNW can offer 12-, 16-, and 24-port configurations SPE vacuum manifolds and 10-port large volume Flash vacuum manifold, which can achieve continuous sample extraction and filtering, simplify complex sample preparation procedures and save time.
Instruction: The manifolds consist of a clear glass chamber and lid to which a vacuum is applied to draw a sample through an SPE column, cartridge, or disk. Adjustable racks placed in the glass vacuum chamber will accommodate a variety of sample collection vessels, including test tubes, autosampler vials, volumetric flasks, and Erlenmeyer flasks. Eluants are deposited directly into the collection vessel of choice via polypropylene, optional stainless steel, or Teflon needles. Drying attachments will direct a flow of air or nitrogen into the collection vessels to dry eluants prior to further analysis. Drying attachments can also be connected, via adapters, to SPE columns or cartridges in order to dry the column or cartridge prior to final elusion. Optional disposable solvent resistant polypropylene containers are available for the 12-port manifolds. These waste containers greatly simplify sample preparation, solvent disposal, and clean-up.
