Sciex Vial Clear Polymethylpentene Pack of 200 Vials

Sciex A62251 PMP Autosampler Vial – 500 µL, Polymethylpentene (PMP)

The Sciex A62251 is a precision-engineered 500 µL autosampler vial designed specifically for high-sensitivity analytical applications, including Capillary Electrophoresis (CE) and HPLC. Manufactured from high-quality Polymethylpentene (PMP), this vial provides the exceptional optical clarity required for visual sample inspection while maintaining the rugged durability and shatter-resistance of a high-grade polymer. PMP is characterized by its superior chemical resistance and exceptionally low surface tension, which significantly reduces the non-specific binding of proteins, peptides, and nucleic acids to the vial walls. This ensures maximum sample recovery and consistent analytical results, even when working with ultra-low concentrations or highly "sticky" biological molecules that typically adhere to standard glass or polypropylene surfaces.

Technical Performance and Design

• Polymethylpentene (PMP) Construction: Combines the transparency of glass with superior impact strength and chemical inertness, making it an ideal choice for volatile solvents and sensitive biological reagents.

• Low Surface Adsorption: The non-polar nature of PMP minimizes the interaction between the sample and the container wall, ensuring that the full concentration of the analyte reaches the capillary or column.

• 500 µL Micro-Volume Format: Perfectly sized for limited-volume samples, providing a narrow interior geometry that allows the autosampler needle to recover nearly the entire sample volume with minimal dead volume.

• Thermal Stability: PMP offers a high melting point and excellent thermal resistance, allowing these vials to be used in temperature-controlled autosampler trays without deformation or leaching.

Key Benefits & Applications

• Capillary Electrophoresis (CE): The standard vial choice for CE workflows where maintaining the ionic balance and concentration of the sample is critical for migration time reproducibility.

• Proteomics & Biologics: Ideal for the analysis of monoclonal antibodies (mAbs), recombinant proteins, and peptides that are prone to sticking to traditional laboratory plasticware.

• Small Molecule Analysis: Provides a chemically inert environment for organic solvent-based samples, preventing the leaching of plasticizers that can interfere with UV or Mass Spec detection.

• Trace Element Analysis: PMP’s high purity and low metal content make these vials suitable for trace-level applications where glass ions (like sodium or boron) might interfere with the results.
