Cobra3 set pH titration with drop counter, 230 V

Product No: 43050-88

Function and Applications

With this set titrations can be carried out, at which the volume of added reagent is determined with a dropcounter. This kind of application is faster and more comfortable than a manual application. Possible measurements are e.g. quantitative analyses, determination of concentrations, determination of dissociation constants of weak bases and acids.

Benefits

This set allows to execute the measurements in a didactical clear and easy way:

small costs
easy to understand for the students
quickly to execute
because the measured values are recorded with an interface the titration curves can be represented easily

Equipment and technical data

It will be delivered complete with tripod material and all necessary small hardware items:

Cobra3-ChemUnit
Software measure
pH-electrode
Immersion temperature probe
Teflon- Drop counter
Magnetic stirrer
Small hardware items
CD with literature

Accessories

Conductivity-probe for the recording of conductivity titration
