Kjeldahl Tablets Titanium 3.5g K2SO4  / 0.105g CuSO4 / 5 H2O / 0.105g TiO2

The original tin had 1000 count, but this tin was not sealed, so we are unable to determine how many tablets are missing. 
Each tablet is 3.71g x 1000 = 3710g which equals 8.1792lbs. This tin weighs 7.92lbs, so some of the tablets are missing. Also, the weight of the tin is not known. Sold as it is pictured.
