PFC-100 fatty acid analyzer Introduction
The PFC-100 automatic fatty acid analyzer is an important instrument for judging the quality of stored grain by changing the fatty acid value. It changes the end point brought by the phenolphthalein indicator to indicate the end point, and the measurement result is not accurate and the comparability is poor. Such problems, based on potentiometric titration, built a unique experimental method for the determination of fatty acids in wheat, wheat and corn, the test is more accurate.
Feature
Built-in grain, wheat, corn fatty acid value test method, the test is more convenient, one-click test; the results show that mgKOH / 100g dry matter, the instrument automatically converts to save the trouble.
Multiple self-test functions simplify operation and avoid misuse.
Powerful application editing function, the user can generate a special titration mode according to the experiment and store it, the next key click.
Built-in burette, the burette is built into the instrument, and the outside can be observed through the window to make the solution completely separated from the personnel during the operation of the solution to avoid damage to the operator.
