Thermo Fisher Scientific Inc recently introduced the new National Scientific Mass Spec Certified Vials, which are cleaned & tested as standard. These low-particulate chromatography vials are, cleaned in a GMP compliant,fully-validated clean room environment, minimizing contamination. Moreover, each lot is tested for particle counts & LC/MS & GC/MS background, providing consistently high performance from each vial. Product integrity is also ensured thanks to the pre-cleaning of packaging, making the vials ideal for a wide range of highly sensitive chromatography applications. The Vials are manufactured from inert, pure & chemically stable glass, & produced under strict QC protocols for uniformity, thanks to the in-process verification of 13 critical physical characteristics, ensuring a reproducible performance is obtained with every use.
