TitraLab 845
Routine Potentiometric Titration Workstation (Bi burette)

With the new multi-technique TitraLab 845 bi-burette titration workstation you can benefit from superior quality results at the touch of a button. Ideal for routine applications, its use is simpler than ever before. The TitraLab 845 represents today the best value for money on the market for routine potentiometric titrations.

 Routine measurement of CIP Acid and Base strength

Acidity of Milk
The acidity of milk is determined by end point titration using 0.1 eq/l NaOH. The end point value is generally fixed at pH 8.7 and the result is expressed in dg/l of lactic acid. This result is also called DORNIC acidity.

Results for 10 determinations
Mean (as grams/100ml of lactic acid): 0.1517
Standard deviation:0.106
Relative standard deviation: 0.7%

Salt in Butter
The silver nitrate reacts with the chloride ion according to (Ag+, NO3-) + Cl- → AgCl (precipitate) + NO3- Then 1 mole of AgNO3 corresponds to 1 mole of chloride. The titrant concentration is generally 0.1M. The results are expressed as a % of salt (NaCl with a molecular weight of 58.453 g/mol).

Results for three determinations on salted butter, generally expressed as a % of sodium chloride ion (MW = 58.453 g/mol)
Mean: 1.995%
Standard deviation: 0.0018%
Rel. standard deviation: 0.09%
(Butter with a salt content of 2%) 

Results for three determinations on butter (with a 10 ml burette), generally expressed as a % of sodium chloride ion (MW = 58.453 g/mol)
Mean: 0.036%
Standard deviation: 0.0003%
Rel. standard deviation: 0.8%

Acidity of Cheese
The acidity of cheese is determined by end point titration using 0.1 eq/l NaOH. The end point value is generally fixed at pH 8.4 and the result is expressed in % of lactic acid, which has a MW of 90.08 g/mol.

Results for 5 determinations, expressed as % of lactic acid (CH3-CHOH-COOH with a MW of 90.08 g/mol)
Mean: 0.97%
Standard deviation: 0.01%
Rel. standard deviation: 1%
