网页2016/05/10 · May 10 2016. Supelco’s Low Adsorption (LA) vials are manufactured using a process that decreases the number of hydroxyl groups on the vial's glass surface, significantly reducing surface activity while improving analytical quantitation and minimising pH shifts in the sample. This same process also removes unwanted surface metals such
网页Most sample vials are made of plastic or glass, and include a separate or attached lid or closure. Sample vials are categorized by material and also by their size or specific purpose. Glass sample vials are categorized by the type of glass used to make them. Type I, Class A glass sample vials are made from low-expansion borosilicate glass.
