Porvair Sciences have a range of clear polystyrene bottom, glass bottom and solid bottom assay plates that are specifically designed for absorbance, fluorescence, luminescence and scintillation applications. Porvair Krystal series clear bottom plates are now recognised as industry-leading tools for Pharma drug discovery and screening.
Filtration plates are used in their simplest form to remove particulate matter from liquid. Either the particulate matter or the filtrate is needed for further study. Porvair Sciences has a range of filter plates to suit most filtration applications. We have optimised filter plates for applications including cell harvesting, DNA separations, binding studies, Plasmid isolation, general filtration and sample clean-up. Porvair has a full range of 48-, 96- and 384-well microplates with a choice of glass fibre, nylon, PVDF or polyethylene filtration materials and well volumes ranging from 350 μl to 5 ml.
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.
