Vacuum Seed Counter

This extremely practical appliance simplifies the laborious and time-consuming counting and depositing of seed for germination. It is particularly suitable for uniformly sized and smooth seed, such as grain, brassica and trifolium. The counter consists of three components: a vacuum system with connecting hose, a series of counting heads corresponding to the different types of seed and of a valve interrupting the vacuum. The intensity of the vacuum can be varied with a potentiometer. The counting heads with 100, 50 or 25 bores are slightly smaller than the paper substrate, and they have a rim avoiding that the seed drops. The diameter of the holes is adapted to the size of the seed and to the suction power of the vacuum.
