Dimensional accuracy and purity are fundamental requirements that you as a user place on sample vials and closures for analysis. You achieve higher reproducibility and avoid possible sources of error right from the start. This is why the procurement of certified products that provide the required proof of quality is becoming increasingly important.
As one of the leading German suppliers of high-quality chromatography accessories and consumables, we take this into account with our range of “Certified sample vials and closures” range. Consistently high quality through comprehensive incoming goods inspection has always been and will always be part of our own standards.
