counting a mixture of different seeds
Contador 2 with feed container #2
This is the sample of 3 mixed seeds

Contador 2 could handle different sizes of seeds by different feed containers.
We tried to count a quite unusual sample (mixture of three species) and found that the result is very close to the countings of the single fractions which we separated by mechanical sieving.
The sum of the single fractions is 7662 seeds whereas the mixture is counted to 7637, so the difference is only 25 seeds (.33%).
The counting takes about 3 minutes.
So, separation as preparation of the sample is no longer necessary.
