DURAN® burette

with straight standard ground stopcock, class B

Calibration is based on the poured out volume (“Ex”) at a 
+ 20 °C reference temperature. Volume content tolerances
conform to DIN and ISO. The Class B accuracy limit is roughly one and a half times wider than for Class AS. The tolerances
are thus more strict than specified by DIN.

Typical application: titrations.
