BOROFLOAT ® has practically the same glass composition as DURAN ®, which is also a SCHOTT glass product mainly used for laboratory equipment.Consequently, the glass is very resistant against water, neutral, saline, acidic solutions, and to iodine, chlorine, bromine, and organic substances, even over long periods and at temperatures higher than 100 °C.
Made from high-quality borosilicate glass, this profile tubing with three or more angles is manufactured by a new, patented, continuous direct drawing process. The main properties are high planarity, surface quality and geometric accuracy. Conturax Pro profile tubing also offers high

High-borate borosilicate glass B2O3 – 15 –25% , SiO2 – 65 –70%, and smaller amounts of alkalis and Al2O3 as additional
Quality control (QC) samples were separately prepared in a similar way as calibration standard, and the concentrations of 0.1, 0.5, and 4.0 μg/mL of VCR in plasma samples were corresponding to low, medium, and high QC, respectively. 2.5. Sample preparation. A 200 μL of plasma sample was mixed with 20 μL of the IS working solution.

The addition of boric oxide with silica is what differentiates borosilicate glass. The following chart details the chemical composition of QVF borosilicate glass 3.3: The purpose of adding boric oxide is to create a less dense product with a higher melting point. The high temperature allowance and superior durability makes borosilicate glass

Non-alkaline earth borosilicate glass (borosilicate glass 3.3) The B 2 O 3 content for borosilicate glass is typically 12–13 % and the SiO 2 content over 80 %. High chemical durability and low thermal expansion (3.3 x 10–6/K) – the lowest of all commercial glasses for largescale technical applications – make this a multitalented glass
