Graduated flasks
Volumetric flasks provide precise results in chemistry and pharmacy. They are not scaled, but have a single ring mark that is drawn all the way round the neck to avoid reading errors.
The narrow neck results in high setting accuracy. In addition, volumetric flasks have bulbous curves in the upper area so that any gas bubbles that form can escape from the solution more easily. However, if there are gas bubbles in the solution, the volumetric flask must be swivelled slightly so that the bubbles rise to the top. In addition to volumetric pipettes and burettes, volumetric flasks are therefore the most accurate volumetric instruments in the laboratory for analysis.
Volumetric flasks, plastic, Class B
Highly transparent PMP. Tolarances Class B acc. to DIN EN ISO 1042. With individually adjusted, red printed graduation and inscriptions and PP standard ground joint stoppers.
The volumetric flasks withstand exposure to temperatures up to 121°C (autoclaving) without permanent loss of tolerance. Recommended cleaning temperature: up to 60°C to preserve printing on the flasks....

Check flasks, DAkkS calibrated, boro 3.3, class A, with 3 marks, blue graduations
BLAUBRAND ®, DIN EN ISO 1042. Calibrated to contain (TC, IN). DAkkS (former DKD) certificate included. The volumetric flask with 3 marks is used to check the functioning of a dispenser. The mark in the middle shows the nominal volume, the upper and lower marks show the error limits as specified in the table below. If the error limit is exceeded even with repeated measurements, the dispenser is defective. The DAkkS-calibrated volumetric flask does not replace the gravimetric test of the monitoring of measuring instruments according to ISO 8655....
