The manifolds yield consistent extraction, elution and filtration
results for up to 24 columns, cartridges or 25 mm syringe filters.
Filters should not be attached to the vacuum manifold port prior to
elution. Filters will air-lock and prevent fluid passage if used during
column conditioning, sample application, or column wash. Using
filters during the final elution step will ensure a clean sample for
injection. Parallel processing of this kind greatly reduces the time
required to prep multiple samples.
The manifolds consist of a clear glass chamber to which vacuum
is applied to draw a sample through on SPE column, cartridge, or
Adjustable racks placed in the glass vacuum chamber will
accommodate a variety of sample collection vessels, including
test tubes, autosamplers, vials, volumetric flasks, and Erlenmeyer
Eluants are deposited directly into the collection vessel of choice
via polypropylene, optional stainless steel, or Teflon needles.
Vacuum manifolds for SPE sample preparation, filtration, and
elution are available in 12, 16, and 24 port configurations.
