Porvair Sciences Microlute SPE sample preparation system

The Porvair Sciences Microlute SPE sample preparation system provides a fast, trouble-free alternative to cartridges for high-productivity sample clean-up. It also enables users to increase their assay sensitivity by providing pre-injection clean-up and concentration on samples as small as 150 µL.

Supplied as a package including filter plate, collection plate, waste tray and manifold, the system contains all the elements to deliver the advantages of high-productivity SPE sample preparation in a convenient microplate format. Microlute SPE plates are available with a choice of sorbent, filter and sample collection plates (350 µL, 1 mL or 2 mL well volumes) to optimally match the user’s sample clean-up requirements.

Using a sorbent slurry loading technique, the plate has been developed to eliminate the channelling effects that typically limit the performance of dry powder loaded SPE columns. Each well on a Microlute plate has an individual drain spout ensuring 100% sample transfer and zero crossover contamination.

To recover dry or concentrated sample, the sample preparation system may be coupled to a Porvair Minivap or Ultravap sample concentrator.
