*   A  = accuracy, CV = coefficient of variation
** EL = error limit (EL = A + 2CV)

The maximum resolution of the display:
25 ml instrument: 0.001 ml, above 20 ml titration volume 0.01 ml;
50 ml instrument: 0.002 ml, above 20 ml titration volume 0.01 ml.

Range of application

The instrument can be used for the following titration media (maximum concentration 1 mol/l):
Acetic acid	Nitric acid	Sodium arsenite solution
Alcoholic potassium hydroxide solution	Oxalic acid solution	Sodium carbonate solution
Ammonium iron (II) sulfate solution	Perchloric acid	Sodium chloride solution
Ammonium thiocyanate solution	Potassium bromate solution	Sodium hydoxide solution
Barium chloride solution	Potassium bromate bromide solution	Sodium nitrite solution
Bromide bromate solution	Potassium dichromate solution	Sodium thiosulfate solution
Cerium (IV) sulfate solution	Potassium hydroxide solution	Sulfuric acid
EDTA solution	Potassium iodate solution	Tetra-n-butylammonium hydroxide solution
Hydrochloric acid	Potassium permanganate solution	Zinc sulfate solution
Iodine solution	Potassium thiocyanate solution
Iron (II) sulfate solution	Silver nitrate solution

The control elements of the Titrette® bottle-top burette have an intuitive layout. Separate buttons for On/Off and Pause; Clear button allows user to reset the display and select functions. Easy-grip hand wheel action and smooth precision gears for fast or drop-wise titration make handling extremely simple and reliable.
