96-Well Round-Bottom Microplates, 0.32 mL/Well — Sterile PS, No Lid, 10/Box
These sterile 96-well polystyrene microplates feature a round-bottom well geometry and a 0.32 mL per-well volume, making them well-suited for cell culture, agglutination assays, hemagglutination inhibition, and any workflow that benefits from uniform cell pelleting. Supplied without lids in a 10/box bulk format, they conform to the standard SBS footprint for seamless integration with multichannel pipettes, automated liquid handlers, microplate readers, and washers. The natural (clear) polystyrene construction provides the optical clarity needed for absorbance and fluorescence measurements across common assay platforms.

Frequently Asked Questions
Are these microplates sterile?
Yes — each plate in the 10/box pack is supplied sterile, making them ready for direct use in cell culture and sensitive assay workflows without additional treatment.
Do these plates include lids?
No, lids are not included. The open-format bulk packaging is intended for high-throughput workflows where plates are processed quickly and individual lids are not required, or where a universal lid is sourced separately.
Are these plates compatible with automated liquid handling systems and standard microplate readers?
Yes — the plates conform to the standard SBS footprint, so they integrate with multichannel pipettes, automated liquid handlers, microplate readers, and washers designed for 96-well format instrumentation.
Why choose round-bottom wells rather than flat- or V-bottom?
Round-bottom geometry provides a curved well surface that encourages uniform cell settling and simplifies resuspension, which is particularly advantageous for agglutination assays, hemagglutination inhibition testing, and general cell culture applications where consistent pelleting matters.
