DURAN® Volumetric Flask, Class A, USP compliant, USP individual certificate, 1000 ml DURAN® Volumetric Flasks are available in two different accuracy classes: A and B. The two classes differ in the tolerances. The two classes differ in the tolerances of the volumes. A is the highest accuracy class, while the error limit of class B is about twice that of class A. The clear DURAN® volumetric flasks with accuracy class A have blue printing. The volumetric flasks according to USP are provided with an individual number. This is permanently lasered into the bottom of the volumetric flask and entered on the corresponding certificate. The error limits of the USP-compliant volumetric flasks are narrower than those of the volumetric flasks with ISO 1042 conformity and thus fulfil the requirements contained in the United States Pharmacopeia (USP). This certificate documents the volume measured for each volumetric flask, the uncertainty of measurement and the date of issue. Special features and benefits: Conforms to ISO 1042 Manufactured from borosilicate glass 3.3 Highest possible precision in volume measurement and high-quality process stability Very accurate determination and measurement of volumes due to precise processing and scaling Supplied with ergonomic polyethylene stopper for fast and safe opening and closing Adjustment to sprue („In“) at + 20 °C reference temperature Tolerances for volume correspond to accuracy class A With printed ring mark for better visibility Burnt-in and therefore permanently durable blue printed image Application: Preparation and storage of normal solutions, measurement of liquid quantities, dilution of solutions, mixing of several components, dimensional analysis, volumetry, To ensure a long service life of the volumetric flasks and to exclude possible changes in volume, these glass products should not be heated above + 250 °C in the drying cabinet or steriliser.
