17.7 mL Microplates, Flat Bottom, PS, Natural — 222-8048-01F | 100/Bag | Caplugs® Evergreen

17.7 mL 6-Well Flat-Bottom Microplates with Lids — Sterile PS, Natural, 100/Bag (222-8048-01F)

These sterile 6-well polystyrene microplates feature a flat-bottom well geometry and a 17.7 mL per-well capacity, making them well suited for ELISA, absorbance-based colorimetric assays, fluorescence assays, and larger-volume cell culture workflows. Each plate ships individually wrapped with a lid included for evaporation control and contamination prevention, and the natural (clear) polystyrene construction delivers the optical clarity required for microplate reader measurements at standard absorbance and fluorescence wavelengths.

Technical Specifications

Applications

• ELISA and absorbance-based colorimetric immunoassays requiring a flat optical surface for uniform path length
• Fluorescence microplate reader assays benefiting from the optical clarity of polystyrene construction
• Larger-volume cell culture incubations where the 17.7 mL per-well capacity accommodates generous media volumes
• Binding assays and reagent incubations with extended hold times — the included lid controls evaporation and reduces contamination risk
• Workflows requiring aseptic technique at point of use, enabled by individual sterile packaging
• High-throughput screening steps compatible with standard single-channel and multichannel pipettes, microplate readers, washers, and incubators

Compatibility

The standard SBS footprint of these 6-well plates ensures broad compatibility with automated liquid handling systems, microplate readers, and washers commonly found in clinical and research laboratories. Standard 6-well spacing accommodates multichannel pipettes, and the flat-bottom well geometry provides the uniform optical path length required by most absorbance and fluorescence readers. The fitted lid allows plates to be stacked for space-efficient storage in incubators and refrigerators without compromising the sterile environment inside each well.

Quality & Procurement

Made in USA, these Caplugs® Evergreen microplates are produced at ISO-certified manufacturing facilities from BPA-free, phthalate-free polystyrene resin. Lot-level quality controls verify consistent well geometry, flat-bottom surface quality, lid fit, and material integrity across every individually packed unit — supporting traceability requirements in CAP-, CLIA-, and ISO 15189-accredited laboratories. LabSupplies.com is an authorized Caplugs® Evergreen dealer and ships from USA inventory, with tiered pricing available for high-volume institutional and grant-funded accounts.

Frequently Asked Questions

Are these microplates sterile, and how are they packaged?
Yes — each plate and its lid are individually packaged sterile, supporting aseptic technique at the point of use without the need for additional decontamination steps before opening.

Is the lid included, and does it allow plates to be stacked?
A fitted lid is included with every plate. It controls evaporation during extended incubations, reduces the risk of cross-contamination, and is designed to allow stable stacking of multiple plates in incubators or cold storage.

Can these plates be used in automated microplate readers and washers?
Yes — the standard SBS footprint is compatible with most microplate readers, washers, and liquid handling systems. The flat-bottom well geometry ensures a uniform absorbance path length for reliable colorimetric and fluorescence measurements.

Are polystyrene plates suitable for solvent-containing reagents?
Polystyrene performs well with aqueous buffers, cell culture media, and standard binding assay reagents. It is not recommended for use with acetone, ethyl acetate, aromatic solvents, or alcohols above 70%, as these can craze or dissolve the material. For solvent-heavy workflows, consider polypropylene alternatives.
