Porvair Sciences range of solid bottom 96-well assay plates is specifically designed for absorbance, fluorescence, luminescence and scintillation applications. The design uses the most popular 96-well format with standard ‘chimney’ wells to overcome optical crosstalk and contamination.

These plates are designed to give optimum results from any instrument which reads from the top of the plate. The acclaimed composite black/white plate has been shown to be ten times more sensitive than a standard white plate for chemi-luminesence assays. Black plates are designed for top reading fluorescence instruments and have low background fluorescence and minimise light scattering. They have a highly polished well to give better readings and a specially designed plate featuring a white well set in a black matrix to overcome the problem of a very high luminescence causing false positives. Working volumes of 350μl/well. Complies with the standard ANSI/SBS format. Alphanumerically labelled wells mean samples can be easily traced
