*(A = accuracy, VK = coefficient of variation)

Error limits related to the nominal capacity (= maximum volume) indicated on the instrument, obtained when instrument and distilled water are equilibrated at ambient temperature (20°C/68°F) and with smooth operation.

The instrument can be used for the following titration media (maximum contentration 1 ml/l):

Acetic acid Iron (II) sulfate solution Silver nitrate solution*
Alcoholic potassium
hydroxide solution
Nitric acid Sodium arsenite solution
Ammonium iron (II)
sulfate solution
Oxalic acid solution Sodium carbonate solution
Ammonium thiocyanate solution Perchloric acid Sodium chloride solution
Barium chloride solution Perchloric acid in glacial
acetic acid
Sodium hydroxide solution
Bromide bromate solution Potassium bromate solution Sodium nitrite solution
Cerium(IV)sulfate solution Potassium bromide bromate
solution
Sodium thiosulfate solution
EDTA solution Potassium dichromate solution Sulfuric acid
Hydrochloric acid Potassium hydroxide solution Tetra-n-butylammonium
hydroxide solution
Hydrochloric acid in acetone Potassium iodate solution Triethanolamine in acetone*
Iodide iodate solution* Potassium permanganate solution* Zinc sulfate solution
Iodine solution* Potassium thiocyanate solution  

*use light shield inspection window

When the instrument is properly handled, dispensed liquid will only come into contact with the following chemically resistant materials:

borosilicate glass, Al2O3, ETFE, PFA, FEP, PTFE, platinum-iridium, PP (screw cap)
