DURAN® Volumetric Flask, Class A, amber, individual certificate, 50 ml DURAN® Volumetric Flasks are available in two different accuracy classes: A and B. The two classes differ in their 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 brown-coloured ones are printed in white. Volumetric flasks that have individual numbering are supplied with an individual certificate. The individual number is permanently lasered into the bottom of the volumetric flask and entered on the corresponding certificate. This certificate documents the volume measured for the respective volumetric flask, the measurement uncertainty and the date of issue. The individual number is a consecutive number and consists of three letters and a 4-digit number, e.g.: AAA-0001. Special features and benefits: Conforms to ISO 1042 Made of borosilicate glass 3.3 UV protection through external colour application; long durability and good chemical resistance of the brown colouring. The purely external brown colouring ensures unchanged DURAN® properties inside the volumetric flask. 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 scribed ring mark Burnt-in and therefore permanently durable white printed image Application: Storage and transport of light-sensitive materials, 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.
