DURAN® volumetric flasks are used for the accurate measurement of specific quantities of liquids. They are volumetric analysis aids in quantitative laboratory work. – complies with ISO 1042 – Calibration based on the poured in volume (“In”) at a + 20 °C reference temperature – Outstanding precision during volumetric measurement and high-quality process stability – Thanks to the exact processing and precisely calibrated scales, they permit the highly accurate determination and measurements of volume – Supplied with ergonomic polyethylene stopper for easy and safe tightening or removal – The volume content tolerances conform to accuracy Class B – Fired-on, highly durable white print – With printed ring mark for better visibility – Influence of undesirable factors is kept to an absolute minimum DURAN® volumetric flasks are used for the accurate measurement of specific quantities of liquids.
