96-Well Conical-Bottom Microplates, 0.30 mL/Well — Sterile PS, No Lid, 10/Box (222-8051-V1K)
These sterile 96-well polystyrene microplates feature a conical bottom geometry and a 0.30 mL per-well capacity, making them well-suited for cell pelleting by centrifugation, wash-based assays, and bead-based protocols where complete recovery from the well bottom is critical. Supplied without lids in a 10/box bulk format, part number 222-8051-V1K conforms to the standard SBS footprint for seamless use with multichannel pipettes, automated liquid handling platforms, microplate readers, and washers.

Applications
- Cell pelleting by centrifugation — conical bottom geometry seats the pellet for maximum recovery after spin
- Wash-based assays and bead-based assays requiring complete cell or bead retrieval
- High-throughput screening and drug discovery workflows in standard 96-well format
- Cell-based assays and immunoassays with absorbance or fluorescence detection
- Automated liquid handling pipelines using standard SBS-footprint labware
- Clinical and regulated laboratory workflows (CAP/CLIA/ISO 15189) requiring lot-traceable consumables

Frequently Asked Questions
Are these microplates sterile?
Yes — each plate is supplied sterile, making them suitable for cell-based assays, cell culture workflows, and other applications where sterility is required right out of the box.
Do these plates include lids?
No — the 10/box format is an open, lid-free configuration intended for high-throughput workflows where lids are not required or are sourced separately.
Will these plates work with automated liquid handling systems and microplate readers?
Yes — the standard SBS footprint is compatible with common automated liquid handling platforms, multichannel pipettes, microplate washers, and readers designed for 96-well format labware.
Can polystyrene microplates be used with organic solvents?
Polystyrene is well suited to aqueous buffers, dilute acids and bases, and methanol in short-term contact, but it is not compatible with aromatic solvents, chlorinated solvents, or ethyl acetate. For solvent-heavy workflows, a polypropylene microplate is the more appropriate choice.
