Vials, Screw Top, Glass. Clear, 2ml, with Write-On Patch and fill lines, 9-425mm threads, 12x32mm outer dimensions. For use as an autosampler vial. RSA Brand. 100/PK.
RSA™ autosampler vials are engineered for analytical applications requiring exceptionally low adsorption, high chemical cleanliness, and reproducible performance. This product family represents MICROSOLV’s most widely adopted vial technology, trusted globally for HPLC, UHPLC, LC‑MS, GC-MS and GC workflows where sample integrity and analytical confidence are critical.
RSA™ (Reduced Surface Activity) vials are not coated or surface‑treated and are not a glass type. Instead, RSA™ products are the result of proprietary MICROSOLV manufacturing processes that precisely control the finished vial’s internal surface characteristics. These processes minimize surface activity and residual metal content while preserving the inherent chemical durability and dimensional stability of the vial.
As a result, RSA™ vials significantly reduce adsorption of basic, polar, and low‑abundance compounds and help eliminate variability caused by vial–sample interactions. Samples remain stable—even in highly aqueous matrices—supporting improved quantitative accuracy and method reproducibility, particularly in mass‑spectrometry‑based analysis.
RSA™ vials are manufactured with ultra‑low residual metal content and exhibit no extractables or leachables, making them well suited for demanding analytical environments. Precision dimensional control ensures reliable compatibility with leading autosamplers and consistent injection performance across routine and regulated laboratory workflows.
This Category includes screw‑top and snap‑top RSA™ vial formats, supporting a wide range of caps, septa options, and sample volumes up to 2 mL. RSA™ vials are commonly used in pharmaceutical, bioanalytical, clinical, environmental, food, and chemical analysis where reliability and data quality cannot be compromised.
Key Performance Characteristics
Reduced adsorption of basic and adsorption‑prone compounds
No extractables or leachables
Ultra‑low residual metal content
No coatings or surface treatments
Consistent autosampler fit and reproducible injection performance
RSA™ autosampler vials are selected when analytical precision, sample recovery, and long‑term reproducibility are essential.
Quality Assurance
RSA™ vials are manufactured under rigorous quality‑control protocols to ensure clean, contaminant‑free packaging and consistent performance. Products are evaluated for surface interaction behavior, metal content, and dimensional conformity. Certificates of QC conformance are available upon request.
Industry Context
When evaluated against conventional and so‑called “certified” vials, RSA™ vials consistently demonstrate lower surface activity and reduced variability, supporting more reliable analytical outcomes across sensitive methods.
