FISHER "COULOMATIC" TITRIMETER ® Silver-platinum, gen· erates silver ions
Platinu m-platinum, generates oxidants, re· ductants
JLHE Fisher Coulomatic Titrimeter automatically, quickly and easily determines mercaptans, halides and thiocyanates to ± 1 % accuracy. A wide choice of electrodes makes possible difficult analyses of m a n y kinds for which there are no other adequate rapid methods. Among other advantages of this flexible laboratory instrument are:
Glass electrode with metal electrode insert
• Self-generating titrants eliminate standard solutions • Repeated titrations in t h e same beaker • Quick determinations w i t h micro-samples
Glass-calomel combination
