Providing the Highest Quality Standards and Instruments Available

AMCO Clear® is an EPA approved primary standard for calibration of turbidity sensors that is safe, non-toxic and disposable. It is easy-to-use with no dilution or resuspension, and it is available in a wide range of values. It is NIST traceable to particle size/distribution and optical density, and its inherent stability means it does not settle from suspension. It has a guaranteed one year shelf life even if you've opened the bottle and happened not to have recapped it tightly. The convenient submicron polymer suspensions are non-toxic primary calibration standards approved by the US EPA for drinking water analysis for turbidity, and preferred by the U. S. Geological Survey for turbidity and sediment transport analysis.

AMCO Clear® is the unique, non-toxic low-level turbidity standard that can reliably read from 0.02 NTU to 10,000 NTU every time.

We offer excellent pricing, fresh material, fast delivery and great technical support.
