Amber Polypropylene Autosampler Vials for Light‑Sensitive and Ionic‑Sensitive Analyses
MICROSOLV™ 9502S‑PP‑AM Amber Plastic Screw‑Top Vials are manufactured from virgin polypropylene, a non‑ionic polymer that significantly reduces interactions between analytes and vial surfaces compared to glass. The amber coloration provides protection for light‑sensitive compounds while retaining the chemical resistance and low adsorption properties of polypropylene.
These 2 mL vials feature 9‑425 screw threads and 12 × 32 mm outer dimensions, making them compatible with most modern autosamplers that accept standard ND9 formats.
Polypropylene Advantages in Analytical Workflows
As a non‑ionic material, polypropylene helps minimize adsorption and ionic interactions that can negatively affect recovery and reproducibility—especially in aqueous and bio‑analytical applications. This makes amber PP vials a strong alternative to glass when analyte stability or surface interactions are a concern.
These vials are particularly well suited for analytical techniques where glass‑related interactions may compromise results.
Molded Construction with Graduations
Each vial is molded from virgin polypropylene with consistent geometry to support reliable autosampler performance. Integrated fill lines and graduations assist with accurate filling and reproducible sample volumes.
The screw‑top design allows use with standard 9‑425 caps and septa selected for the specific application.
Recommended Applications
The 9502S‑PP‑AM plastic autosampler vial is commonly used for:
