Introduction Culture Plates are ideal for cell culture and cell harvesting; available with five different growth surface areas either surface-treated or non-treated. Growth surface areas are flat and free from striation to maximize usable growth area and transparency. Manufactured of (USP class VI) virgin polystyrene to eliminate all extraneous materials and ensure the integrity of your cells. The surface of treated plates is modified with plasma causing the otherwise very hydrophobic polystyrene surface, to become negatively charged and hydrophilic, allowing cells to attach and multiply. Raised rims on wells reduce the risks of cross-contamination and nestle into rings on the lid to reduce evaporation. One direction lid has venting system that assists in controlling gaseous exchange. A rim on the top of the lid is designed for secure stacking. All plates are sterilized by gamma irradiation and individually packaged in paper/plastic peel pouches; non-pyrogenic. Feature Uniform wall thickness ensures distortion-free well bottoms. Each well is labeled with alphanumeric marking . Available DNAse/RNAse free . Non-toxic . Gamma radiation sterilization.
