Eliminate manual labeling and bring greater productivity to your lab. The innovative Virtuoso system transfers text, graphics, barcodes, and logos directly onto your vials thereby ensuring accurate sample identity, sample security, and traceability.

Achieve secure, repeatable crimps or remove seals with minimized risk of damage. Our manual crimpers are reliable and easy to use. Our electronic crimpers provide adjustable settings for compatibility and crimp-force sensing that automatically determines a proper seal.

Remove interfering materials and fine particles from a wide range of samples for more consistent and reliable results. These high quality robust syringe filters offer lower extractibles for a cleaner sample, higher burst pressures, and improved flow through.

Use certified clean, low particle, low background vials for your LC/MS, GC/MS, and chromatography high sensitivity applications. Our Certified Vial Kits (assembled and unassembled) are fully lot-tested and every pack comes with a Certificate of Conformance.
