About this item
- The HI-723-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Chromium VI High Range Checker HC
- These reagents follow the Diphenylcarbohydrazide Method in which the reaction between chromium VI and the reagent causes a purple tint in the sample. By simply adding the packet of HI-723-25 reagent to the sample, the reaction will take place and the HI-723 will determine the concentration from the colour that is produced.
- The HI-723-25 are the replacement reagents for the HI-723 Chromium VI High Range Checker HC 25 Tests Sku: HI-723-25

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
