DURAN® Burettes, Straight PTFE Stopcock, Class AS, Amber
Burettes
Burettes with PTFE key and straight standard ground joint, made of highly chemically resistant borosilicate glass 3.3. Their precise scaling makes them particularly suitable for titrimetric purposes.

  • UV protection through amber glass
  • The volume content tolerances conform to accuracy class AS
  • Easy-to-read scale with graduation marks to estimate the content
  • Waiting time: 30 seconds
  • Fired-on, highly durable white ceramic

The quantity of liquid required for titration, which is unknown beforehand, can be precisely read off once the reaction is complete.

Unlike the glass keys, the PTFE keys need not be greased, which makes work in the laboratory easier.

Calibration is based on the poured out volume ('Ex') at a +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.

Certifications: Complies with ISO 385.

Delivery information: Supplied with with batch certificate and certificate of conformity.
