Dosing Pump
The dosing pump is based on a valve that automatically moves the titrant between the titrant
bottle and syringe when filling the syringe and between the syringe and sample when dispensing.
A replaceable 5 mL plastic syringe is used to limit the amount of titrant used per test to ensure the
highest possible accuracy. Before a set of titrations, it is necessary to prime the dosing system.
Note:
Once titrations have been completed, the dosing system should be cleaned with deionized
water using the prime feature.
