Volumetric flasks, Blaubrand, 3 marks, class A, PP-stopper, bue printing

Brand® volumetric flasks provide the highest accuracy. Strict statistical quality controls ensure maintenance of these high standards.

Volumetric flasks are indispensable for preparing dilutions and standard solutions.

Standard volumetric flasks are supplied with a square-grip PP stopper with a dripping tip. These stoppers reduce the danger of breakage if a flask tips over, and help to prevent it from rolling off the workbench. These volumetric flasks are also available with glass stopper.

All Blaubrand® volumetric flasks are supplied with a batch number and an accompanying batch certificate in the original packaging.

On request, they are also available with an individual certificate, USP individual certificate or DAkkS (formerly DKD) calibration certificate.

Brand ® manufactures glass volumetric instruments in accordance with current DIN EN ISO standards.  Specified error limits are observed with at least 99.6% reliability. Brand® confirms this by including batch, individual, or DAkkS certificates, which also show that the Brand® products frequently perform far beter than specified error limits.

Blaubrand® volumetric instruments are robust, so that they provide a long service life. 

Blaubrand® volumetric instruments can be heated up to 250°C in a drying cabinet or sterilizer without causing permanent change in volume.

The reference temperature 20°C applies to Blaubrand® volumetric instruments.

The testing of volumetric instruments is done gravimetrically according to DIN EN ISO 4787.

The volumetric flask Blaubrand®  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 replacet he gravimetric test of the monitoring of measuring instruments according to ISO 8655.
