Corning Culture Microplate with Lid 24 Well 3.4 ml Individually Sealed Case of 50 Plates

Corning® Costar® 24-Well Clear Flat-Bottom Tissue Culture-Treated Microplates with Lids (3526) – Case of 50

The Corning® Costar® 3526 is a premier, research-grade multi-well plate engineered for cell culture maintenance, downstream biochemical screening, and scale-up assays. Fabricated from premium, high-purity virgin polystyrene, each plate features a 24-well configuration with an optical flat-bottom base that eliminates light scattering and birefringence during microscopic analysis. The interior growth surface of each individual well undergoes a standardized, vacuum-gas plasma tissue culture (TC) treatment, introducing hydrophilic oxygen functional groups to maximize cell attachment, spreading, and replication stability. Supplied as a commercial case of 50 individually paper-plastic peel-wrapped plates with matching lids, this model ensures strict aseptic barriers for clinical, diagnostic, and academic research installations.

Technical Performance & Design Architecture

• Vacuum-Plasma Surface Treatment: The surface modification process converts the hydrophobic polystyrene base into a uniform hydrophilic substrate. This permanent treatment promotes reliable cell adhesion and division across all 24 wells, suppressing variable well-to-well cell cluster mapping.
• Condensation-Control Non-Reversible Lid: The included clear polystyrene lid incorporates dedicated condensation rings matching the 24-well matrix. This design ensures safe gas exchange while minimizing evaporation rates and preventing aerosol drop-drift contamination across adjacent wells.
• Aseptic Peel-Pack Isolation: Every multi-well plate is packed individually in a medical-grade paper/plastic blister pouch. This allows operators to easily peel open the packaging and transfer the sterile unit into a laminar flow biosafety cabinet without introducing ambient laboratory dust or debris.
• Molded Alphanumeric Tracking Coordinates: Features high-contrast, raised alphanumeric labeling (Rows A–D, Columns 1–6) around each well rim. This tracking layout simplifies rapid sample identification during manual loading loops and facilitates liquid handling automation teaching steps.
