Mar 22, 2020 · Type I glass has the least pH shift, lowest leaching characteristics, linear coefficient of expansion 33 or 51, 33 for clear autosampler vials and 51 for amber vials. USP Type I , 33 Borosilicate Glass is the most inert and chemically resistant glass widely used in laboratories especially for chromatography applications.
Standard Opening Crimp Top Vials, 12x32mm, 11mm Crimp Finish. Closures. Aluminum Seals, Lined. Made of the highest quality aluminum; for use with standard 11mm chromatography vials. The open top allows for filling and retrieving samples with a syringe. Seals are available in a variety of colors for easy sample identification.
Apr 06, 2022 · Because of the lack of fluxing agents, high silica glass is extremely hard to melt, with a deformation temperature as high as 1,700ºC, meaning it can be used at such high temperatures as around 1,000 o C. High silica glass has a very low thermal expansion, very good chemical durability, optical properties, and mechanical properties, but the
glass, have a low coefficient of expansion and very high resistance to chemical attack. It has low alkali content and is free of elements from the calcium, magnesium, and zinc group of heavy metals. The total of combined oxides of arsenic and antimony is less than 0.005%. 33 expansion borosilicate glass meets the requirements for Type I Class A glass of ASTM E438.

1. The glass adopts high-quality borosilicate glass tube, with low free ion content, low expansion coefficient and very high chemical resistance. 2. The unique thread design can ensure the consistency of the seal. 3. Strict quality assurance provides dimensional consistency between batches. 4.
6.3.3.1 Borosilicate glass. Borosilicate glass is a type of glass with the main glass-forming constituents’ silica and boron oxide. Borosilicate glasses are known for having very low coefficients of thermal expansion (∼5 × 10 −6 / °C at 20 °C) making them resistant to thermal shock more so than any other common glass.
