Labels applied to all 4 sides of the plate. No sequence number duplicates. Exceptional print quality and resolution. Resistant to commonly used laboratory reagents. Resistant to temperature ranges of -80ºC to +52ºC. See Product Details below for bar code label specifications. Microplate Features Ideal for whole cell or subcellular high content screening. Can be used with high throughput confocal imagers, and has been optimized with the Amersham InCell 3000 Analyzer. Ultra flat thick well bottom is designed for high throughput imaging by minimizing microscope refocusing from well to well. More economical solution than glass bottom plates. Better cell growth and attachment than glass bottom plates. Black opaque walls to prevent well-to-well crosstalk. TC-treated for optimal cell attachment.
