Whatman Microplate 250 ul Uniplate 96 Well Case of 50 Plates

Description

Whatman UNIPLATE 96-Well Microplate – 250 µL, Natural Polypropylene, V-Bottom, Non-Sterile (MPN: 7701-5250)

The Whatman 7701-5250 (manufactured under Cytiva) is a commercial-grade 96-well UNIPLATE™ collection and analysis microplate engineered for high-recovery liquid handling, sample archiving, and automated fractionation. Molded from premium, chemical-resistant natural polypropylene (PP), this plate features a standard 8 × 12 well layout with a maximum nominal volume capacity of 250 µL per well. The specialized V-bottom (conical) well architecture features perfectly vertical sidewalls that channel fluids down into a pointed apex base. This configuration enables exceptional sample recovery rates up to 99%, making it highly effective for low-volume compound management, filtrate collection, and automated liquid handling applications where dead volume must be minimized.

Technical Performance and Design

• High-Recovery V-Bottom Apex: The combination of vertical well sides and a steep, pointed V-shaped base concentrates fluids at the absolute center of the bottom. This architecture minimizes capillary retention and residual dead volume, delivering a typical 99% liquid sample recovery profile.

• Advanced Polypropylene Resilience: Formulated from pure, translucent natural virgin polypropylene, providing high chemical compatibility with aggressive solvents, including Dimethyl Sulfoxide (DMSO), alcohols, and mild acids without material leaching or structural swelling.

• Anti-Cross-Contamination Design: Engineered with flat, smooth interwell borders and uniform well openings to enable a consistent surface for sealing. This design supports a secure evaporative barrier when paired with adhesive films, thermal heat-sealing foils, or reusable cap mats.

• Rigid Automation Form Factor: Though designed with high-density structural integrity to withstand high-g forces within multiwell swing-out plate centrifuges, the plate is optimized for error-free interaction with robotic plate grippers, automated liquid handlers, and workstation stackers.

Key Benefits & Applications

• High-Throughput Assay Collection: The benchmark collection vessel for collecting filtrates from 96-well filter plates or vacuum manifold systems during high-throughput solid-phase extraction (SPE) or DNA miniprep cleanups.

• Micro-Volume Compound Storage: Highly valued for compound library storage and serial dilutions involving expensive reagents, allowing small volumes to be completely retrieved during automated pipetting passes.

• Ultra-Low Deep Freeze Archiving: Built to maintain physical durability and remain completely shatter-safe during long-term storage in deep-freeze environments down to -80°C.

• Clear Alphanumeric Grid Orientation: Features clean, embossed alphanumeric grid markings along the perimeter borders to ensure rapid visual sample mapping and mistake-free plate indexing.
