DURAN® 2000 ml Class B volumetric flask, PE stopper

DURAN® volumetric flask, class B, 2000 ml The DURAN® volumetric flasks are available in two different accuracy classes: A and B. The two classes differ in the tolerances of the volumes. A is the class with the highest accuracy, while the error limit of class B is approximately twice that of class A. DURAN® products with accuracy class B have white printing. A general glass specification is available on request for these products. Special features and benefits: Complies with ISO 1042 Made of borosilicate glass 3.3 Highest possible precision in volume measurement and high-quality process stability Very accurate determination and measurement of volumes through precise processing and graduation Supplied with an ergonomic polyethylene stopper for quick and safe opening and closing Adjusted to contain (“In”) at a reference temperature of + 20 °C The tolerances for the capacity correspond to accuracy class A With a printed ring mark for better visibility Fired-in and therefore permanently durable blue printing Application: Preparing and storing standard solutions, measuring liquid quantities, diluting solutions, mixing several components, quantitative analysis, volumetry, To ensure the longevity of volumetric measuring instruments and prevent any changes in volume, these glass products should not be heated above + 250 °C in a drying oven or sterilizer.
