Water Hardness Buffer, VWR Chemicals BDH®
Made with deionized water, ammonium chloride, ammonium hydroxide and EDTA magnesium salt.
- Enhanced stability during measurements
- Improves reproducibility of testing water hardness
- Helps negate wild changes in pH or temperature during testing
The buffer should be handled with care. Buffer solution improves the quality of water hardness testing by insulating against changes in pH or temperature.
