The cartridges are designed
with both manual and automated uses in mind. All of our solid phase extraction syringe cartridges are equipped with male Luer-tips, providing great versatility for connections
and processing.
Common processing methods include
using a syringe plunger to introduce the
sample/solvent into the syringe barrel,
placing the SPE cartridge into a centrifuge
and pulling the sample/solvent through the
cartridge by centrifugal force, or boring a
hole in a rubber stopper to accommodate
the SPE cartridge and placing the stopper in
a vacuum flask. Vacuum aspiration is then
used to pull the sample/solvent through the
cartridge.
In a similar application, multiple cartridges
may be used to process multiple samples by
using an adapter and vacuum manifold
hooked up to a vacuum source. Sample
throughput may also be increased by using
large-reservoir SPE cartridges. Combined
with other automation methods, significant
gains in lab efficiency may be achieved.
