3.5 mL Microplates, Flat Bottom, PS, Natural — 333-8024-01F | Caplugs® Evergreen

24-Well Flat Bottom Microplates with Lids — TC Treated, Sterile, Polystyrene, Individually Packed (333-8024-01F)

These 24-well microplates feature a flat bottom design with a 3.5 mL per-well capacity, molded from natural (clear) polystyrene and supplied with individual lids for contamination control. Each plate is tissue-culture treated and sterile, making them suitable for cell-based work requiring reliable surface attachment and aseptic handling. Individually packed to preserve sterility until point of use, 333-8024-01F is well suited for cell culture, screening, and other plate-based laboratory workflows.

Technical Specifications

Applications

• Adherent mammalian cell culture requiring a TC-treated surface for reliable cell attachment
• Primary cell and co-culture experiments benefiting from the larger 3.5 mL well volume
• Compound screening and dose-response assays in a 24-well format
• Sample incubation and plate-based assays where a flat-bottom well is required for imaging or absorbance reading
• Any sterile cell-based workflow where individually sealed packaging is needed to maintain aseptic conditions

Material & Chemical Resistance

Polystyrene provides the optical clarity and rigidity that are standard for cell culture microplates, and performs well with aqueous media, standard biological buffers, and saline-based reagents. As with all PS labware, polystyrene is not compatible with acetone, alcohols above 70%, or aromatic and chlorinated solvents, which can craze, crack, or dissolve the material. Polystyrene is not autoclavable; sterility is achieved and maintained through the individual packaging supplied with each plate.

Quality & Procurement

Made in USA, Caplugs® Evergreen 24-well microplates are produced under ISO 9001 quality management from BPA-free, phthalate-free, latex-free resin. Each plate is individually packed to preserve sterility through transport and storage. LabSupplies.com is an authorized dealer and ships from USA inventory, with volume and institutional pricing available for high-throughput and grant-funded laboratories.

Frequently Asked Questions

What does tissue-culture (TC) treated mean, and why does it matter?
TC treatment is a surface modification — typically a corona discharge or similar process — that renders the polystyrene hydrophilic and negatively charged at physiological pH, promoting protein adsorption and enhancing attachment of anchorage-dependent cells. It is the standard surface for routine adherent cell culture.

Is each plate individually sterile, and how is sterility maintained?
Yes. Each microplate is supplied sterile and individually packed, so the sterile barrier remains intact until you open that specific plate. The lid included with each plate provides additional contamination protection during use.

Can these plates be used with standard microplate readers or imaging systems?
The flat-bottom well geometry is compatible with absorbance-based microplate readers and inverted microscopy for general cell observation. Always confirm the specific footprint and well geometry against your instrument's requirements before committing to bulk purchase.
