Mar 22, 2020 · Coefficient of Expansion = 92. USP Types II, III and NP glass are manufactured from soda-lime which has less chemical resistance than borosilicate Type I glass vials. Special Glasses . Silanized or deactivated glass vials are borosilicate glass bottles that have undergone further deactivation by treating the surface of the glass with an organosilane. The surface becomes more hydrophobic and inert making the vial suitable for use with pH sensitive compounds, trace analyses and applications

Aijiren Tech™ Silanized Glass Vials are treated by vapor phase deposition silanization method. Surface deactivation treatments such as silanization and siliconization may play an important role in preserving the integrity of certain materials or extracts stored in glass containers.

Mar 30, 2012 · Our MicroSolv brand vials are made from SCHOTT® brand glass tubing, of first hydrolytic class. First hydrolytic class glass is very hard and has a low expansion coefficient, even when large variations in manufacturing temperatures are observed. It has an excellent chemical resistance to acidic, neutral and relatively low alkaline solutions.

Chromatography & Autosampler VialsFeatures: 2ml sample vial are made of high quality borosilicic acid glass,low content of free ions,low coefficient of expansion and very high che

Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including

100 X Autosampler Vials 2ml HPLC. $22.99. LOW EXPANSION COEFFICIENT - 9mm Screw Thread Autosampler Vials are made of clear Type 1, Class A Borosilicate Glass with very low expansion coefficient. It shows excellent chemical resistance to acidic and neutral solutions, due to its relatively low alkaline content even to alkaline solutions.

Some budget vial glass has a linear coefficient expansion. GUIDELINES FOR AUTOSAMPLER VIAL SELECTION. The lower the coefficient of expansion the better the glass can handle vials are often used for ion chromatography because of the extremely low metal. Autosampler Vials, Membrane Solutions 2ml HPLC Vials, 9-425 Lab . LOW EXPANSION COEFFICIENT

Borosilicate Glass vials are the preferred choice for gas chromatography and liquid chromatography (GC/LC). These vials are generally free of potential contaminants that may interfere with analysis of the sample. Borosilicate glass is made by adding boron trioxide to silica for extreme heat resistance with a very low expansion coefficient

12x32mm very low expansion coefficient autosampler glass vials silicone/PTFE bonded septa 9 mm Certified Clear Glass Vial with Blue Screw Top and PTFE These convenience kits hold 100 2 mL Clear Screw Top Vials and 100 preassembled Blue Caps with PTFE/Red Rubber Septa together in an env

Mar 06, 2020 · All brown glass is B-grade glass, with a linear expansion coefficient of 51. Silanized or deactivated glass The borosilicate hydrochloride glass, which has been deactivated by organosilylation, has strong hydrophobicity and inertness on the glass surface, which is suitable for pH-sensitive compounds, trace analysis and long-term sample storage.

Almost all vials are made out of 1st hydrolytic class glass. First hydrolytic class glass is very hard and has a low expansion coefficient even at high temperature variations. It shows an excel-lent chemical resistance to acidic and neutral solutions, and even to alkaline solutions due to its relatively low Alkali content. Higher

unless otherwise specified and has an expansion coefficient of 51. Silanized or chromatography because of the extremely low metal ... vial even if there is a very ...
