Shopping Cart icon  Ordering Information
  • Reduced Surface Activity Vials, Inserts & Ultra Pure Caps for Chromatography
  • Meets or Exceeds all Instrument Specs with high quality, RSA™ Glass
  • Use for LCMS, LCMS/MS, Low abundance & Basic Analytes

RSA™ vials & inserts made with Reduced Surface Activity glass (RSA™) were developed for the separations laboratory that investigates low abundance analytes or samples that are pH sensitive, basic in nature or when using mass spectrometers. Chosen when coatings or silanization is not sufficient or counter indicated for good results with LCMS, GCMS or UHPLC.

  • How does RSA™ glass work…

  • What does RSA™ glass do…
        When using all other borosilicate glass autosampler vials & inserts commercially available, sample diluents (such as water) can de-protonate the many hydroxyl groups on the wall of your vial which produces a negative charge on the glass. The “acidic” functionality of these silanols has been known to cause adsorption of basic compounds, change the pH of the sample solution and/or hydrolyze some susceptible compounds making them undetectable. The surface metals in your current vial contaminates and can cause precipitation, chelation or other changes in your samples while in the vial. Don’t let sample prep continue in your vials.

  • With RSA Glass™ vials and inserts there is virtually no…
        basic compound “adsoprtion to the vial”, no “pH shifting of your sample diluent” or other problems from the reactivity of the vial surface thus making your analysis more reliable, lot-to-lot, run-to-run and day-to-day. This is an excellent feature for low dosage form pharmaceuticals

  • Every batch of RSA™ glass is tested…
        for adsorption, pH stability and metal counts as well as standard fit and form specs using LCMS, pH and Ion selective electrodes. Certificates of Conformance to these QC tests are available. Lot support for investigations are available as well.

  • Used by instruments companies for years as their brand of vials. Detect low abundance analytes normally adsorbed by glass
  • Prevents pH changes in vials before injection even hours later
  • Prevents sample hydrolysis that can occur in your vials
  • No meniscus when water is used as the main solvent
  • Not Coated or silanized
    * Not touched by human hands
    * Special boxes for vials reduces contamination from outgassing
  • Available in “Easy Purchase Packs”; one catalog number for matching vials and caps in one package.

  • Not all vials are created equal...
        The sample handling process is one of the most expensive in a separations lab and the final container you entrust it to before analysis is critical. In this “final container”, you do not want or expect to find changes to your samples, diluent or other analytes due to vials or caps that are not made for sample handling, specifically chromatography.

        In this “final container”, you do not want or expect to find extractables, dirt, dust or manufacturing residue in the vials or caps. RSA™ glass vials & inserts offer assurances of quality reliability due to our own specifications and in process and batch testing. Immediately packaged after learing by robots these vials are never touched by human hands. Certificates of conformance are available upon request.
The AQR Brand™ caps and septa are manufactured and quality tested the same way with extremely high standards for extractables, pierce-ability and resealing and these can be certificated as well upon request. Available with Soft Guard™ fitted ultra pure septa in the caps.
