A general glass specification is available on request for these products. Special features and advantages: 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 Calibrated to contain (“In”) at + 20 °C reference temperature The tolerances for the volume correspond to accuracy class A With a printed ring mark for better visibility Fused-in and therefore permanently durable blue print Application: Preparation and storage of standard solutions, measuring liquid quantities, diluting solutions, mixing several components, titrimetric analysis, volumetry. To ensure the longevity of volumetric measuring instruments and exclude possible volume changes, these glass products should not be heated above + 250 °C in a drying cabinet or sterilizer.
