Pump Calibration Standard for Titratable Acidity in HI84429 Dairy Mini Titrator$25.00
The HI84429 dairy products acidity mini titrator incorporates a peristaltic pump dosing system for the accurate delivery of a titrant. The HI84429-55 is a pump calibration standard that is used to calibrate the dosing system. A calibrated dosing pump allows for the accurate determination of the amount of titrant used when performing a titration. The amount of volume dosed along with the concentration of the titrant is used by the pre-programmed formula within the HI84429 in determining the exact acidity of dairy products. The pump calibration procedure should be performed anytime the titrant or pH electrode is replaced. Routine calibration is recommended to ensure the highest of accuracy when performing a titration.
- Pre-measured solution
- Clearly marked expiration date and lot number
- Air tight bottle with tamper-proof seal to ensure quality

The determination of acidity is made according to a neutralization reaction in which the acids found in dairy products are neutralized by a base. In the United States the acidity of dairy products is usually expressed in terms of lactic acid (% l.a.). Other units of measure include degree Soxhlet Henkel (°SH), degree Dornic (°D) and degree Thorner (°Th).
For precise results it is very important to know the sample volume, titrant volume, and titrant concentration. As the titrant comes pre-standardized, it is important to determine the amount of titrant delivered by the dosing pump. This determination is done by the pump calibration procedure. In this procedure the analysis of a known volume of a known solution (HI84429-55) is titrated with the HI84429-50 titrant to the pH endpoint that is potentiometrically determined by the FC260B pH electrode and HI5315 reference electrode. The pump calibration procedure should be performed anytime the titrant, syringe, tubing or pH electrode is replaced. It is recommended to do a pump calibration every time a new set of titrations are to be performed.
The HI84429-55 is a 500 mL bottle of pump calibration standard solution that is used for the determination of acidity in dairy products. The number of pump calibrations performed will vary on the method selected.
