The GermPro 7010 makes measuring the enzymatic activity in germs or embryos of grain kernels and
seeds fast and simple. Its accelerated vacuum reactor promotes a reaction that occurs when enzymes,
found naturally in grains, come into contact with a tetrazolium salt solution. When a grain capable of sustaining germination comes into contact with the solution a color change occurs which stains the
germ red. By examining the grains it is easy to determine the germinative capacity of the sample.
HOW IT WORKS
A solution containing Tetrazolium salt is used as a reagent. This liquid is
sensitive to Hydrogen Creating enzymes. The hydrogen produced by the action of these enzymes
will reduce Tetrazolium to a light red colour (RED FORMALAZIN), when a germ capable of
germination is in contact with the solution. If the seed is incapable of germination, no colour is
produced. Please note, if pale stains are present with a slight brown colour this may indicate heat
damage and the 4mlGE test may give a low result for the first 2 days as the vigour of the seed
may be reduced as it deteriorates.
It is important that when the reaction takes place, a vacuum is created to accelerate the process,
hence the hand pump supplied with each GermPro. As a result, tests take only a few minutes
instead of several hours normally required by conventional methods.
The GermPro’s portable, rugged construction means that this analysis can be carried out anywhere that grain is
tested, in the store, at the dockside or in a grain laboratory. The powerful hand held vacuum pump accelerates
the reaction allowing the analysis time to be reduced from hours to minutes compared with traditional testing methods.
