Caps - AQR™ Brand Screw & Snap

Manufactured & matched with RSA™ vials | For the very best chromatographic results... Every time.

The AQR brand™ caps and septa are manufactured and tested for consistent quality with extremely high standards for extractables, pierce-ability and resealing. Certificated for conformance upon request.

When working with low abundance analytes it's important that no extraneous peaks that could be from your vial or vial cap occur. LCMS and GCMS might detect even trace amounts of color or impurities from a septum. AQR™ caps and septa provide the necessary ultra-purity for trace analysis.
