DURAN® burette bottle, with NS 29/32, clear, 2000 ml

DURAN® burette bottle, with standard ground joint NS 29/32, clear, 2000 ml The original DURAN® burettes are made of the chemically highly resistant borosilicate glass 3.3. The precise scaling makes them particularly suitable for titrimetric purposes. The quantity of liquid required for titration, but unknown beforehand, can be read off very accurately after the reaction has been completed. Adjustment is made to run-off ("Ex") for + 20 °C reference temperature. This means that the quantities can be read 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 plugs. PTFE plugs, unlike glass plugs, do not need to be greased, which simplifies laboratory work. Special features and advantages: Replacement bottle for automatic burette Supplied without accessories Application: Titration, volumetry, dimensional analysis
