Analytical TrueTaper Collection Plate 1 ml 96 Well Total of 5 Plates

Analytical Sales TrueTaper 96-Well Collection Plate – 1 mL Volume, 50 µL Tapered-Bottom Wells, SiliGuard Low-Bind Coating, Virgin Polypropylene (MPN: 968810GC)

The Analytical Sales 968810GC (also distributed under wholesale ID NC0749030) is a premium, instrument-grade TrueTaper® 96-well collection microplate precision-engineered for maximum sample recovery in high-throughput analytical liquid chromatography (HPLC/UHPLC) and mass spectrometry (LC-MS) workflows. Featuring a standard 96-well round format with a total capacity of 1 mL per well, the plate is distinguished by its unique 50 µL tapered-bottom well profile. This design geometry optimizes low-volume pipetting and significantly reduces dead volume by creating a higher fluid meniscus than standard round or flat-bottom plates. Injection-molded from high-purity virgin polypropylene, the plate is enhanced with a proprietary SiliGuard™ low-bind surface coating that prevents non-specific binding (NSB) of delicate proteins, peptides, and small molecules to the polymer walls.

Technical Performance and Design

• TrueTaper Conical Well Geometry: Engineered with round tops that transition into ultra-precise 50 µL tapered bottoms. This profile forces small sample fractions into a concentrated apex, maximizing fluid draw efficiency for autosampler needles and reducing sample waste.

• SiliGuard Low-Bind Matrix Coating: Chemically modified with a ultra-thin SiliGuard surface shielding. This specialized barrier eliminates secondary silanol or hydrophobic interactions, ensuring exceptional recovery lines for challenging, sticky polar compounds and biomolecules.

• Virgin Polypropylene Construction: Molded using high-clarity, medical-grade virgin polypropylene resin. Completely free of common manufacturing lubricants, slip agents, and heavy plasticizers that can leach into solvents and contaminate mass spec baselines.

• Evaporation and Cross-Talk Defense: The raised well-rim structure provides a secure, flush mating plane for silicone cap mats, heat seals, and adhesive foils, minimizing well-to-well crosstalk and sample evaporation during long testing runs.

Key Benefits and Applications

• High-Sensitivity LC-MS/MS Assays: The industry-preferred choice for sample preparation and injection sequences where compound loss due to container-wall binding cannot be tolerated.

• Pharmacokinetic & MetID Screening: Highly effective for preparing, organizing, and spinning clinical blood serum extracts, plasma fractions, and small-volume metabolic study samples.

• Automated Autosampler Deck Stability: Rigid structural framing allows the plate to adapt easily onto automated liquid handlers, robotic gripper platforms, and high-pressure autosampler injection trays without flexing.

• Clamshell Contamination Shielding: Packaged by the manufacturer in specialized rigid clamshell housings rather than cheap bags to minimize ambient electrostatic charge, preventing cross-contamination from cleanroom dust particles before use.
