AquaLab Verifi cation Standards

Application Note
Using AquaLab is easier then ever. Pre-packaged standard salt solu-
tions are immediately available for performance verifi cation, saving
you time and money. Validation and documentation for GMP and
GLP has also become easier. Operate your instrument with certainty
and insure the quality of your food product by using low cost preci-
sion salt solutions.
No need to purchase and store reagent grade salts.
No additional laboratory equipment necessary.
Avoid solution handling and mixing errors.
Save technician time.
Th e AquaLab should be verifi ed against a known salt standard daily.
For high use or batch processing, the instrument should be checked
regularly against a known salt standard of similar water activity.
Checking the water activity of a standard solution will alert the op-
erator to the possibility of contamination of the unit or shifts in the
linear off set from other causes.
Now, you can verify AquaLab performance with confi dence. Per-
formance Verifi cation Standards come in four water activity levels;
0.984, 0.760, 0.500, and 0.250 a . Th e standards are produced un-
w
der a strict quality assurance regime. Th e accuracy of the standards is
