The unique Krystal 2000 plate range from Porvair Sciences has been optimised for luminescence and fluorescence assays. A patented manufacturing process, using a ‘two-shot’ mould, provides clear, individual wells in an opaque matrix. The special design of the plate totally eliminates the well-to-well optical crosstalk inherent with other clearbottomed microplate designs, giving unmatched accuracy, sensitivity and repeatability of photometric readings. Very high signal-to-noise ratio and low detection limits can be achieved with this superb plate. All tissue-culture treated plates are supplied lidded and sterile, in individual bags.
