Vials, Screw Top, Plastic. Translucent, 2ml, 9-425mm threads, 12x32mm outer dimensions. For use as an autosampler vial. MICROSOLV Brand. 1000/CS.
Additional Info:
The MICROSOLV 9502S‑PP‑CLEAR plastic autosampler vial is our most popular plastic vial and a proven replacement for traditional glass autosampler vials in analytical laboratories.
Manufactured from pharma‑grade virgin polypropylene, these 2 mL, blow‑molded vials feature consistent wall thickness, molded fill‑line graduations, and a slightly concave bottom designed to help reduce residual sample volume. The translucent PP‑Clear formulation improves visibility over opaque plastic while maintaining polypropylene’s chemical resistance and low surface activity.
As a non‑ionic material, polypropylene significantly reduces or eliminates adsorption of proteins, peptides, and basic compounds that commonly interact with borosilicate glass. This makes these vials especially well‑suited for bio‑analytical and trace‑level applications.
Key Advantages
Low adsorption polypropylene (PP) Minimizes analyte loss due to surface interactions versus glass.
PP‑Clear translucent material Improves sample visibility while retaining chemical compatibility.
Concave vial bottom Helps reduce dead volume and residual samples.
Consistent blow‑molded construction Reliable geometry for autosampler operation.
Standard autosampler dimensions Compatible with most systems accepting 12 × 32 mm, 9‑425 vials.
Recommended Applications
These plastic autosampler vials are commonly used for:
HPLC and UHPLC
LC‑MS and LC‑MS/MS
Ion Chromatography (IC)
Capillary Electrophoresis (CE)
Bio‑analysis (proteins and peptides)
PFAS analysis. View an article on PFAS testing.
Glass‑free sample containment where adsorption is a concern
Autosampler Compatibility
Designed for use with most modern autosamplers that accept 12 × 32 mm vials with 9‑425 screw threads. Compatible with standard 9‑425 screw caps and septa.
