Glass-Bottom Microplates

The ultra-flat Krystal series of glass bottom microplates from Porvair Sciences Ltd. provides high performance for high-throughput screening and tissue culture applications.

The automation-compatible Krystal plates combine the optical properties of glass, low background, and low birefringence with the versatility of a microplate. Precision engineered using a polystyrene frame and a borosilicate glass sheet fixed to the base with a biocompatible adhesive, Krystal plates offer a +/- 50-μm degree of planar flatness across the base, excellent light transmission, and a flat optical plane for growing cells.

A nominal cut-off wavelength of 335 nm allows most fluorescence assays to be excited or read through the plate glass bottom, increasing measurement precision and eliminating read errors when performing cell-based assays using fluorescent or luminescent imaging.
