Model No. 4425000
The Labconco Digital Chloridometer is a dedicated coulometric titrator designed to determine the chloride ion concentration of a solution. It displays this concentration in milliequivalents of chloride per liter when 10 micro-liter or 100 micro-liter samples are used. Some typical samples are serum, urine, biological extracts, food product extracts, industrial effluents and other aqueous solutions. The combination of silver ions and chloride ions is a quantitative reaction that results in an insoluble precipitate of silver chloride (AgCl). This reaction is carried out at a constant rate by passing a fixed direct current between a pair of silver electrodes immersed in an acid solution. The anode, which is consumed in this reaction, is a continuous spool of silver wire. As the immersed portion of the wire is consumed, fresh wire is drawn from the spool. As the equivalence point of the reaction is reached, an increase in current between a pair of separate indicator electrodes is detected. At a preset indicator current, the instrument automatically stops the incremental counter and the generation of silver ions. Since the generator current is constant, the titration time is directly proportional to the number of chloride ions that are introduced into the sample vial. The instrument displays this relative time in units of milliequivalents of chloride per liter.
The Digital Chloridometer is an instrument requiring no special installation procedures. Simply connect the AC line cord to a grounded wall outlet and the instrument is ready for operation. No warm-up time is required.
