If only a limited volume of sample is available, you will have to choose between using an insert for your regular autosampler vial, a microvial or a high recovery vial. Note: Most 12x32 mm autosampler vials hold between 1.5mL to 2.0mL of liquid, depending on where the manufacture measures the vial full.
Jan 12, 2001 · A trick, which minimizes the delay time is to place the electrolyte vials used as inlet reservoirs in the autosampler in the positions directly adjacent to sample vials . However, this parameter seems not to be very important, as other researchers did not find a decrease in precision even if a delay time of 6 s was inserted [29] .
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.
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.
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.
Color: Clear Vial & Red PTFE septa Features: 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
1.5ml 9mm Short Thread Autosampler Vials ND9 are made of clear Type 1, Class A Borosilicate Glass with a writable label for sample identification. Material: USP Type 1, Class A, 33 Borosilicate Glass Volume: 2ml (standard volume) 1.5ml(actual volume) Application: HPLC and GC system Dimensions: 11.6 x 32mm Neck Diameter: 9mm Qty/Pack: 100pcs/pack
Low thermal expansion. With a thermal expansion coefficient of at least 3.2 x 10-6 1/K, pure borosilicate glass is significantly more resistant to temperature changes where other types of glass may become warped or deformed. Its strength in thermal shock exposure makes the material suitable for laboratory heating and cookware.
Oct 21, 2014 · First hydrolytic class glass is very hard and has a low expansion coefficient even at high temperature Autosampler Vial • Universally compatible on almost all autosamplers, thereby ...
The thread sits much higher on the vial allowing space between the bottom of the thread and the shoulder of the vial. Order silanized vials to minimize adsorption of polar compounds, including amino acids, proteins, and phenols to the inner surface of the vial. High-recovery vials deliver high sample capacity with very low residual volume.
very low and very high pH applications. Clear Glass Vials can be made from different coefficient of expansion glass; most notable 33-expansion and 51-expansion glass. All Waters 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.
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.
available, you will have to choose between using an insert for your regular autosampler vial, a microvial or a high recovery vial. Note: Most 12x32 mm autosampler vials hold between 1.5mL to 2.0mL of liquid, depending on where the manufacture measures the vial full.
Jan 01, 2018 · CE autosampler vials were filled with the solutions and the voltage was applied for 2 h. This would represent six injections of 20 min each. After this, the pH of the BGEs in the vials was measured.
GUIDELINES FOR AUTOSAMPLER VIAL SELECTION. Some utilize robotic arms to pick up a sample vial; some use tray rotation while The lower the coefficient of expansion the better the glass can handle. Aijiren Vials and Sample Containment Solutions Brochure. of type 33-51 coefficient of expansion for top performance. 100K aved al ls meters. 120.
