Description

Their precise scaling makes them particularly suitable for titrimetric purposes. The amount of liquid required for titration, but previously unknown, can be read off very accurately after the reaction has been completed.

The original DURAN™ burettes are made of highly chemically resistant borosilicate glass 3.3. Their precise scaling makes them particularly suitable for titrimetric purposes. The amount of liquid required for titration, but previously unknown, can be read off very accurately after the reaction has been completed. Adjustment is made to drain (Ex) for + 20°C reference temperature. This means that the quantities can be taken exactly according to the scale, since the adhesion of the liquid to the glass was taken into account during calibration. The tolerances for the volume correspond to the error limits of ISO and DIN. DURAN™ burettes are available with glass or PTFE keys. Unlike glass keys, PTFE keys do not have to be greased, which simplifies work in the laboratory.

  • Calibration is based on the poured out volume (Ex) at a + 20°C reference temperature.
  • With circular ring graduations
  • The quantity of liquid required for titration, which is unknown beforehand, can be precisely read off once the reaction is complete.
  • With Schellbach stripe
  • The volume content tolerances conform to accuracy class AS
  • waiting time: 30 seconds
