Ultra-Flat, Quartz Bottomed Microplates

Porvair Sciences


Black Krystal UV quartz-bottomed microplates exhibit high optical transmission in the 185- to 1100-nm wavelength range, making them ideal for laboratories tasked with circular dichroism (CD) measurements. Manufactured from ultra-pure-grade black polystyrene, these plates exhibit very low autofluorescence and are resistant to solvents, including alcohols, DMSO, and PBS, which are widely used in CD spectroscopy. The plates are precision engineered to deliver a high degree of planar flatness (±100 µm) across the optical surface of all wells, which enables imaging and ultrasensitive CD measurement of proteins and other biological molecules through the base of the plates. The plates are offered in a choice of convenient ANSI/SLAS-compliant 96- or 384-well formats.
