High Range 20 Titrant for Titratable Acidity in Dairy Mini Titrator

$35.00

The HI84529-51 is a 120 mL bottle of titration solution for the High Range 20 range of the HI84529 Titratable Acidity Mini Titrator for Dairy Analysis. The HI84529 mini titrator measures acidity in two different ranges (high and low). There are three different titrant solutions available based on the range to be used and the weight of the sample, each having a different concentration. The HI84529-51 is for titration in the high range (0.1 to 2.0 %l.a.) using a 20 mL or 20 g sample. The titrant is pre-standardized, eliminating the need for any volumetric glassware or a analytical balance and making titrations fast, accurate, and simple to perform.

Pre-standardized titrant
Clearly marked expiration date and lot number
Air tight bottle with tamper-proof seal to ensure quality

The HI84529-51 is a 120 mL bottle of alkaline titrant solution used for the High Range 20 range that determines 0.1 to 2.0% lactic acid in dairy products.

The methodology for titratable acidity in dairy products is based on a neutralization reaction of the acids in a sample (e.g., lactic acid) with a base (e.g., sodium hydroxide) to produce water:

H⁺+OH^- → H₂O

In an ideal solution, the endpoint of an acid titration corresponds stoichiometrically to the complete neutralization of the acids present. The endpoint for this reaction can be determined visually using a color indicator (e.g., phenolphthalein); however, this endpoint becomes very subjective in opaque and colored samples such as milk. The HI84529 removes this issue by titrating to a fixed pH endpoint that is potentiometrically determined by the FC260B half-cell pH electrode and HI5315 half-cell reference electrode.

Replacement reagents required to operate the HI84529 include:

	Low Range 20 (LR 20) - %l.a.: 0.01 to 0.20	Low Range 50 (LR 50) - %l.a.: 0.01 to 0.20	High Range 20 (HR 20) - %l.a.: 0.1 to 2.0
