Solid phase extraction (SPE) is a method of sample preparation that concentrates and purifies analytes from solution by sorption, followed by elution of the analyte with a solvent appropriate for instrumental analysis, such as LC-MS. Porvair Sciences offers a complete range of products to implement SPE. MicroLute™ is the original 96-well plate format for SPE. This device consists of a polypropylene 96-well plate loaded with a choice of sorbent and sorbent volumes. The frits have a mean pore size of 20 microns and are made from microporous high-density polyethylene.
IRIS™ sorbent plates from Porvair Sciences are available in six different phase chemistries offering maximum flexibility for method development.
BioVyon™ Co-sinter products are made using a solid-state media created from an ultra-pure and highly modified polymeric material with the lowest levels of extractables and leachables.
This is a 96-well polypropylene plate with a bottom polyethylene frit already in place. It is designed to allow packing with any material required for chemical synthesis.
There are two bottom frit sizes are available from Porvair Sciences, 10μm and 30μm, however, we recommend the use of 30μm top frits to ensure a good flow rate in both cases.
Drain cap mat that seals the bottom of the plate, preventing liquid leakage.
The Protein Precipitation Plate, P3, from Porvair Sciences is based on the industry standard MicroLute™ format, but without the chromatographic sorbent.
