The higher density of the glass surface gives it a higher water resistance. In glass of the 1st hydrolytic class one differentiates between glass with coefficients of expansion 33 (type 1, class A) and 51 (type 1, class B), whereby brown glass is only available with expansion coefficients 51 worldwide.

Vial/Glass quality comparison, 1st hydrolytic class glass types, 33 vs 70. 33 expansion glass, clear 70 expansion glass, clear 20 μm 20 μm 200nm 200nm When we talk about glass quality for chromatography autosampler vials, we mostly talk about first hydrolytic class borosilicate glass with different expansion
Clear Glass of 1st hydrolytic class is differentiated by 33 expan-sion (Type 1, Class A) and 51 expansion glass (Type 1, Class B), whereas amber is generally worldwide only available as 51 expan-sion glass. The indicated lower expansion coefficient of 33 implies that this harder clear glass has to be processed at higher tempera-tures. These
Glass Type All vials are made from 1 st hydrolytic class 51 expansion glass. The physical properties allow the manufacturing of clean, precision fit vials. Vials manufactured with alternative expansion glass lead to inferior quality with greater tolerances and extractables.
The vials are made from 1st hydrolytic class 51 expansion glass. The vast range of vials includes micro and fused inserts, standard 2ml autosampler and larger sample storage, headspace and EPA vials. EPA Vials & Caps HPLC & GC Autosampler Vials HPLC & GC Caps Inserts Kit packs with vial, assembled cap and septa Sample Storage & Collection
“Chem AS Engineering” Ltd. offers vials, caps and closures for HPLC, LC/MS and GC analysis which are designed to ensure contamination-free sample handling and trouble-free autosampler operation. The vials are made from 1st hydrolytic class 51 expansion glass.
