96-Well Round Bottom Microplates — TC Treated, Sterile, Polystyrene, White, 10/Box (333-8094-W1R)
These 96-well microplates feature a round-bottom well geometry with a 0.32 mL per-well volume, molded from polystyrene and supplied tissue-culture (TC) treated and sterile for cell-based work. The white plate format enhances luminescence and fluorescence signal detection by reflecting light back through the well. Supplied 10 plates per box, part number 333-8094-W1R is well suited to high-throughput cell culture, cytotoxicity assays, and other applications where a TC-treated surface and round-bottom geometry are required.

Applications
- Adherent and suspension cell culture requiring a TC-treated surface
- Luminescence-based cell viability and cytotoxicity assays, where the white well walls maximize signal reflectance
- Fluorescence intensity assays benefiting from the reflective white plate background
- Compound screening and dose-response studies in a standard 96-well format
- General cell-based assays where round-bottom geometry facilitates cell pelleting by centrifugation
Material & Chemical Resistance
Polystyrene is the established material for tissue-culture microplates, offering clarity, dimensional stability, and good compatibility with aqueous biological media, standard buffers, and culture reagents. PS is not resistant to acetone, alcohols above 70%, or aromatic and chlorinated solvents, which can craze or dissolve the material; polystyrene microplates are not autoclavable and should not be exposed to dry heat sterilization.

Frequently Asked Questions
Are these microplates truly sterile, and how are they packaged to maintain sterility?
Yes — the plates are supplied sterile and are individually packaged within the 10/Box format to protect the TC-treated surface and maintain sterility until the point of use. Handle under aseptic conditions once the packaging is opened.
Why choose a white plate over a clear plate for cell-based assays?
White well walls reflect emitted light back toward the detector, which increases signal intensity in luminescence and fluorescence assays. For applications requiring optical transparency or colorimetric absorbance readings, a clear plate would be more appropriate.
Is the round-bottom well design compatible with centrifugation for cell pelleting?
Round-bottom wells are commonly used when pelleting cells or beads by centrifugation, as the geometry encourages cells to collect at the center of the well bottom. Always verify that your centrifuge rotor accepts standard SBS-footprint microplates before use.
