Microlute Sample Preparation System0 pages

Microlute - the complete 96-well sample
preparation system from Porvair Sciences
For more than twenty years, Porvair’s Microlute
96-well SPE plates have been helping scientists
increase the throughput of their analytical laboratory by
speeding up sample preparation. With a range of quality
sorbent materials available, including cation- and anionexchange resins, Microlute sets the industry standard
for 96-well plate based solid phase extraction.
The complete Microlute system provides a matched
filter plate, vacuum manifold and
choice of collection plates with the
option of a dedicated sample
concentrator if needed. Microlute
plates are designed to fit most
available manifolds and conform to
ANSI/SBS standards. Combined with
the Porvair Sciences acrylic vacuum
manifold, they provide a
simple, cost-effective sample
clean up method,
suitable for use in
medicinal chemistry,
compound synthesis
and purification.

For biological sample clean up –
such as protein and phospholipid
removal prior to analysis – Porvair
Sciences offer the Microlute P3
device. This protein precipitation
plate is simple to use and
enables cost-effect
de-proteination using easy
procedures. Acetonitrile or
methanol is added to
serum or plasma
samples to crash the
protein out of
solutions. Porvair
Sciences’ proprietary
superhydrophobic membrane technology ensures that no
precious sample comes through until you are ready to
apply vacuum and collect the filtrate. No agitation
needed, no caps or seals and no messy, inefficient valves

underneath. You get simple, fast, clean, clear samples
every time. The Microlute P3 is setting new standards for
drugs of abuse screening, neonatal metabolic disorders
and many other biological assays worldwide.
The clear acrylic sides of the Porvair Sciences manifold
allow you to see quickly and easily that the filter drip
directors are aligned to the collection plate. With Porvair
Sciences’ deep well collection plates, you get virgin pure
polypropylene that won’t
contaminate your samples with
extractables or additives from the
plastic. In addition, they are
available in THREE convenient sizes,
which optimise your sample
recovery – 2ml, 1ml and 350 µl. To
make your life easier, all three
collection plates are the same
height – so no adjustment or
fiddly spacers are
needed when used in
the Porvair acrylic
manifold.

With a solid base plate made from
chemically resistant acetal, you don’t
need to worry about spillage in the
manifold either. For added
reproducibility and compliance with
SOPs, a premium manifold is
available, fitted with a vacuum
gauge.
To help you reduce
costs in the laboratory,
Porvair also provide
inexpensive, disposable
waste trays made from
polycarbonate, so that
waste eluent can be cheaply and quickly eliminated.
Once again, these waste trays are designed to fit exactly
into the Porvair manifold plenum chamber in order to
catch all the waste liquid.
