• Inner surfaces are treated to produce a negatively charged, hydrophilic surface for consistent cell attachment. Wells are round with a flat bottom and are free from striation to maximize usable growth area and transparency. • Each well is labelled with large alpha-numeric markings for easy identification. A raised rim nests into the rings of the single direction lid to reduce evaporation and limit the risk of cross contamination. • The lid also features an exterior stacking ring for added stability when handling tall stacks of plates. • Plates are sterile (gamma irradiated) and individually packaged in paper/plastic peel pouches that are designed to keep the plates in pristine condition during transit. RNase-free, DNase-free, DNA-free and non-pyrogenic. Lot number is printed on each pouch. • Manufactured in accordance with ISO 9001:2000 quality management systems in a class 100,000 cleanroom. • CELLTREAT™ products include a comprehensive quality certificate with every case of product. The certificate includes the part number, lot number, sterility assurance level and dosage, endotoxin/pyrogen-free assurance, non-cytotoxicity assurance and RNase/DNase-free assurance. • Sterility Assurance Level = 0.000001.
