This germination system, known by the name of "Copenhagen table" or "Jakobson table" can provide a controlled environment for the seeds to be tested. This environment is achieved by providing the seeds with a constant temperature and an accurately controlled moisture level, all the seed samples receiving the same treatment.
The test bed consists of a number of glass strips in parallel above a waterreservoir. Between the strips there are grooves which provide access to the waterreservoir. The whole construction is made out of stainless steel 304. The base of the table is a stainless steel frame. Within this frame a compartment is provided in which the temperature controlsystem, the waterbath with heatingelement and the circulation- pump is located. The water in the reservoir circulate through this waterbath where the temperature of the water is controlled by an electronic digital temperature controller. This will give an accurately water temperature
