DURAN® Burette, Amber, Class AS, with glass key, 100 mL

  • Complies with ISO 385
  • Manufactured from borosilicate glass 3.3
  • UV protection through amber glass
  • The quantity of liquid required for titration, which is unknown beforehand, can be precisely read off once the reaction is complete.
  • Thanks to the precise scale they are ideal for titration
  • Calibration is based on the poured out volume (“Ex”) at a + 20 °C reference temperature.
  • Fluid quantity released can be exactly taken from the scale, as the liquid adhesion to the glass is taken into account in the calibration.
  • waiting time: 30 seconds
  • With circular ring graduations, straight standard ground stopcock
  • Fired-on, highly durable white print

Product Overview
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.
