Customise
your system to
every application
The ABU52 Biburette
comes complete with all
necessary accessories.
Extending your system
couldn’t be simpler:
Add extra capacity
Each ABU52 gives you two motor driven burettes two electrode inputs
and one temperature input Two ABU52s can be connected to a TitraLab workstation
providing up to six titrating burettes and six high impedance electrode
inputs in one system meeting every application need Use the ABU52 as an
extra titration sample stand or for electrode storage and reconditioning.
Automate your system
The required ABU52 burette and installed electrode are selected
via methods programmed in the titration workstation with the system
taking charge of precise titrant or reagent dispensing The large screen
display gives you information about reagent status at a glance.
Ensure fast and accurate dispensing
Choose from five monoblock burette sizes 1, 5, 10, 25 and 50 ml all conforming
to the ISO 8655-3 standard The full volume can be dispensed in less than 20
seconds with a resolution as small as 0.1 µl with the 1 ml burette.
Use as a stand alone dosing unit
The ABU52 can be operated manually by simply connecting a standard PC keyboard
Just fit the right electrode and the ABU52 becomes a versatile manual titration
unit mV/pH readings are shown on the large screen for each titrant increment
dispensed along with a live titration curve Graphic tools enable you to determine
the location of your equivalence point(s) manually in order to calculate the
final result.
The ABU52 Biburette is a complete solution:
Two high resolution burettes with a wide choice of
volumes to add burette capacity to your TitraLab workstation or for
manual/dosing titration.
Two high impedance electrode inputs with differential measurement
mode plus one for imposed current to add electrode capacity to your
TitraLab workstation or for manual titration.
A sample stand with stirring to hold and recondition electrodes not
in use or to perform manual titration.
Two bottle holders for keeping reagents securely in place.
A full set of accessories and cables for easily completing your workstation
installation.
