Are you currently using Hach spectrophotometers and tired of the high cost of original Hach reagent vials? Lianhua prefabricated reagents are a perfect drop-in replacement, no need to change your existing Hach instrument or purchase new equipment.
Take our COD reagent as an example: Model LH-COD-YZ55: 20–1500 mg/L, tolerates chloride up to 2000 ppm, digestion at 150℃ for 2 hours, same protocol as Hach. Our Kenya customer has completed verification and confirmed stable, accurate test data. If you want higher testing throughput, you can upgrade to LH-COD-YZ51: same compatibility, only 20 min digestion at 150℃, greatly shorten your batch analysis time.
Not only COD! We also have pre-vial reagents for Ammonia Nitrogen, Total Phosphorus, Total Nitrogen, all compatible with Hach instruments.
✅ Direct replacement
✅ Comparable accuracy
✅ Faster digestion option
✅ Significantly lower running cost
Help your lab cut expenditure and improve testing efficiency without sacrificing data quality. We can provide free sample support for your verification test.
