BI-ZTU

Autotitrator


Features at a glance
  • Titrations with acids, bases, salts, and
    surfactants.
  • 4 metering pumps for ultimate
    versatility.
  • Disposable sample cups.

Product Description

The BI-ZTU, autotitrator option for the Brookhaven ZetaPlus and ZetaPALS zeta potential analyzers is ideal for automatic determination of the isoelectric point, the IEP, of colloidal materials. Four pumps provide unparalled flexibility for optimizing reagent use. The dramatic savings of reduced labor costs will also encourage larger scale studies that will produce more valuable results.
In addition, the BI-ZTU can be used to evaluate the effect of salt concentration on zeta potential. Also, the surfactant costs can be minimized. Use the BI-ZTU to find the minimum concentration at which the zeta potential does not significantly change.
Easy Operation
Attach the power supply to the rear of the BI-ZTU. Connect the BI-ZTU to the zeta instrument using the standard USB cable. Install the software from the CD. Fill the four 100 mL standard reagent bottles. Insert the tubes. Replace the plug-in electrode assembly with the flow cell. You are ready to go.
Integrated, Simple Software
When the BI-ZTU option is added to a Brookhaven zeta potential instrument, the Titrator command appears in the main menu bar. The software automatically guides the user through an autotitration experiment. User friendly dialog boxes guide even the inexperienced operator through each step.
