Question
Are reagents manufactured by other companies compatible with Hach spectrophotometers and colorimeters?
Summary
Non-Hach reagents on Hach spectrophotometers and colorimeters.
Answer
Testing has not been done to determine if reagents manufactured by other companies are compatible with Hach methods on Hach spectrophotometers or colorimeters.

If a customer wishes to use non-Hach reagents on their equipment, it is recommended they test standards and run appropriate quality control (QC) to validate the results. The same recommendations would apply if a customer wanted to use Hach reagents on a non-Hach spectrophotometer or colorimeter.

Furthermore, Hach spectrophotometers and colorimeters do allow for user calibration curves. A new calibration curve can be constructed using reagents from other companies. However, the accuracy and precision of these curves is the responsibility of the user generating them.
