Metrohm Titrino 719 S Instructions For Use Manual Download Page 129

 

5.2 Connection of electrodes, preparing titration vessel 

719 S Titrino 

125

 

 

Practical tips 

• 

Glass electrodes should be preconditioned in the solvent used for 

ca. 1 hour. 

• 

If the potential jump after the first dispensing step is too large, a 

small start volume may help. 

• 

As an "auxiliary electrode", the 6.1808.030 burette tip with earthing 

may be used in some cases. Use burette tips without anti-

diffusion valve!
