Burettes / automatic burettes are always calibrated to deliver (TD, Ex).
BLAUBRAND® - waiting time 30 sec
SILBERBRAND - no waiting time
(A waiting time is usually not neccessary if a titration is performed (see DIN EN ISO 385)).
All BLAUBRAND® burettes and automatic burettes are supplied with a batch number and an accompanying batch certificate in the original packaging. On request, they are available also with an individual certificate, USP individual certificate or DAkkS calibration certificate.
The needle-valve stopcock
PTFE valve spindle
Operates smoothly and is yet tight, even without lubrication, so there are no grease residues on the burette. The valve spindle is replaceable.
Tight seal without force
A gentle turn is all it takes to close the burette valve.
Precision burette tip
Precise drop by drop control. Drop size remains
constant - from the first to the last drop.
The liquid stream breaks off precisely and
does not creep along the outside edge.
