I believe the product that was mentioned a couple of days ago was Mercoquant test strips for peroxide They are available from Merk KGaA 64271 Darmstadt Germany Tel (06151)720 They work in the range of 0.5 - 25 mg per litre of H2O2 (Hydrogen peroxide) I assume the person requiring these wants to test the natural peroxide in honey. These strips should work in honey although the stickyness may be a bit disconccerting. The strips work on a colour change reaction to peroxide. They are easy to use and reliable Hope all goes well Andrew
