The Sinar GermPro 7010 is a fast and simple tool for measuring the enzymatic activity in germs or embryos of grain kernels and seeds. It uses an accelerated vacuum reactor to promote a reaction that occurs when naturally-occuring enzymes in grains come into contact with a tetrazolium salt solution. When a grain capable of sustaining germination comes into contact with the solution, the instrument stains the germ red. By examining the amount of red-stained grains, it is easy to det
