Universal Polystyrene Microplate Lids

A key technical feature of these lids is the A1 Corner Notch (on select models), which perfectly aligns with the orientation of Corning microplates to prevent accidental 180° rotation—essential for maintaining data integrity in high-throughput screening. For researchers performing fluorescence or luminescence assays, the Black Universal Lid offers the added benefit of protecting light-sensitive reagents and fluorophores from ambient light degradation.

Features:

• A1 Alignment: Corner notch design ensures the lid is always placed in the correct orientation relative to the wells
• Light Protection: The black polystyrene option is specifically designed for light-sensitive assays, preventing photobleaching of samples
• Sterile Assurance: All lids are sterilized by gamma radiation and are certified nonpyrogenic
• Rigid Construction: Manufactured from high-quality polystyrene to prevent warping and ensure a consistent seal
• Automation Friendly: Standardized dimensions (5.020 x 3.365 in) ensure compatibility with robotic plate grippers and stackers

Application Insight:

• Fluorescence/Luminescence: Use the Black Lid (3935) to minimize background noise and protect signal intensity during long-term incubation or reagent addition steps
• Cell Culture: The Clear Lids (3099/3098) allow for microscopic inspection of the wells without removing the lid, preserving the sterile environment
• Standardization: The 0.350 inch height of the notched lids provides sufficient clearance for most standard-well volumes while fitting comfortably in incubator racks
