0.37 mL Microplates, Conical Bottom, PS, Natural — 222-8030-01F | 100/Box | Caplugs® Evergreen

Quick Reference

Technical Narrative

The Caplugs® Evergreen 222-8030-01F is a 96-Well Flat Bottom PS Sterile Microplate with Lid, 0.37 mL per well, individually packed, 100/Box. The flat-bottom 96-well plate is the universal format for adherent cell culture, ELISA, fluorescence-based assays, and spectrophotometric plate-reading — the flat well bottom provides uniform light path for absorbance measurements across all 96 wells and a flat surface for adherent cell attachment and monolayer culture. The matching lid maintains sterility during incubation, reduces evaporation, and prevents aerosol contamination in biosafety cabinet use.

PS: standard cell culture-grade polystyrene with surface treatment for enhanced cell attachment in adherent culture. Optically clear for plate reader compatibility (UV-Vis, fluorescence, luminescence). BPA-free, phthalate-free, FDA-compliant,

Procurement economics: $250.30/Box (100 plates), $2.5030/plate. Sibling: 222-8031-01V (96-Well Conical Bottom 0.30 mL/well IP). LabSupplies.com ships from USA inventory, typically same business day.

Clinical & Research Laboratory Applications

Caplugs® Evergreen 96-well flat-bottom PS sterile microplates with lids serve cell biology, immunology, biochemistry, and infectious disease laboratories as the universal format for plate-based assays and adherent cell culture. The 96-well flat-bottom plate is the standard format for ELISA (enzyme-linked immunosorbent assay) — the flat PS well bottom provides a uniform optical path for plate reader absorbance measurements at the standard ELISA wavelengths (405, 450, 490 nm). Cell biology laboratories use flat-bottom 96-well plates for adherent cell culture assays — cell viability (MTT, MTS, resazurin), cytotoxicity (LDH release), proliferation (BrdU, EdU), and reporter gene assays (luciferase, GFP) — where a flat monolayer culture surface is required. The individually packed format with lid maintains sterility for each plate until the individual wrapper is opened at the BSC.

Frequently Asked Questions

Are the 96-well microplates sterile?

Yes. Sterile — each plate individually packed with lid, 100/Box.

What is the difference between flat-bottom and conical-bottom (222-8031-01V) 96-well plates?

Flat bottom : uniform flat PS well surface — standard for adherent cell culture, ELISA, and spectrophotometric assays where a uniform optical path and flat cell attachment surface are required. Conical bottom (222-8031-01V): V-shaped conical well bottom — concentrates cells or beads at the well tip for pelleting assays, agglutination read (bead/cell button), and any assay where maximizing recovery from the well bottom is important.

Is the 96-well flat-bottom plate compatible with standard plate readers?

Yes. The 96-well SBS/ANSI-footprint PS plate (128 mm × 86 mm) is compatible with all standard plate readers (SpectraMax, Synergy, Varioskan, CLARIOstar, etc.) that accept standard SBS-format plates. PS is transparent in the visible range (400–750 nm) for standard colorimetric and fluorescence detection. For UV absorbance (<320 nm) measurements, UV-transparent plates are required — standard PS plates are not UV-transparent.
