How are your vials packaged to ensure no contamination?

All MicroSolv brand vials that carry a CleanPack label on the front side of the PP-Box have been packed in a certified clean-room class 10,000 after having passed the oven at approximately 600°C. 

These highly hygienic conditions are a pharmaceutical standard; however, new for chromatography vials. Thus, the consumer can rely on clean, uncontaminated vials for a correct analysis.
