1st hydrolytic class glass 51 expansion meets all current USP and Pharmacopeia criteria; Short thread screw vials and caps: convenient handling of mid volatiles; Crimp vials and caps: for low evaporation of highly volatile samples; Snap vials and caps: convenient handling of low volatile samples; Amber vials ensure integrity for light sensitive

The Vials used for the experimental part All the vials used are from 1st hydrolytic class borosilicate glass, but with different expansion coefficients, reaching from 33 type to 51 type basic glass. One vial was additionally silanized, meaning that the surface is inactivated. Instrumentation/Method Time experiment from 0 hrs. to 24 hrs.

Clear Glass Vials can be made from different coefficient of expansion glass; most notable 33-expansion and 51-expansion glass. All Aijiren Technology Clear Glass vials are made from of 33-expansion glass. The alkali content is low and 33-expansion glass has very low free ion content. Figure 1.

Clear Glass of 1st hydrolytic class is differentiated by 33 expansion (Type 1, Class A) and 51 expansion glass (Type 1, Class B), whereas amber is generally worldwide only available as 51 expansion glass. The indicated lower expansion coefficient of 33 implies that this harder clear glass has to be processed at higher temperatures. These amount
