GE Microplate 96 Well 500 ul Deep Well 40 Plates

GE Healthcare 28-4039-43 Deep Well Microplate – 96-Well, 500 µL, Polypropylene

The GE Healthcare 28-4039-43 is a precision-engineered 96-well deep-well plate designed for high-throughput sample preparation, chemical library storage, and protein purification workflows. Manufactured from medical-grade, high-purity polypropylene, this plate offers exceptional chemical resistance against aggressive solvents such as DMSO, ethanol, and methanol, while ensuring ultra-low non-specific binding of proteins and nucleic acids. Each well features a 500 µL working volume, providing a critical mid-range capacity between standard microplates and larger 2 mL blocks. The round-bottom well geometry facilitates maximum sample recovery and efficient mixing, while the standardized SBS footprint ensures seamless integration with automated liquid handling systems, robotic plate stackers, and plate centrifuges. This plate is an ideal choice for laboratories requiring a chemically inert, high-capacity vessel for genomic research, drug discovery, and analytical chemistry.

Technical Performance and Design

• Polypropylene Construction: Provides superior thermal stability, making the plate suitable for deep-freeze storage down to -80°C and safe for autoclaving if required.

• Mid-Range 500 µL Capacity: Specifically designed for protocols that exceed the volume of standard 300 µL plates but require a more compact vertical profile than standard 1 mL or 2 mL deep-well blocks.

• Standard SBS Footprint: Fully compliant with industry standards for microplates, ensuring 100% compatibility with automated workstations from manufacturers such as Tecan, Hamilton, and Beckman Coulter.

• Enhanced Sealing Surface: Features raised well rims to improve the effectiveness of heat-sealing films and adhesive mats, significantly reducing the risk of well-to-well cross-contamination and sample evaporation.

Key Benefits & Applications

• Protein Purification: The round-bottom design is ideal for the resuspension of protein pellets and magnetic bead-based separation protocols.

• Compound Library Management: The DMSO-resistant polypropylene ensures the integrity of small molecule collections during long-term storage and repeated plate entries.

• Genomic Sample Prep: Often used in DNA/RNA extraction protocols where larger volumes of lysis buffers or wash reagents are necessary compared to standard PCR-plate workflows.

• Space Optimization: The 500 µL profile allows for higher density in freezer racks compared to standard 2 mL deep-well plates, maximizing limited ultra-low temperature storage space.
