Germ Testing Papers
For carrying out germ resistance tests. All papers are made from high-purity cellulose and are free of spores, bacteria and toxic substances that could influence the germination of the seeds. The highly absorbent papers store water for the entire duration of the tests. All germ test papers meet the requirements of ISTA and AOSA. Reliable seed testingConductivity 40 mS/mpH value between 6.0 and 7.5High absorbanceRoots do not grow through the paperPapers conform to ISTA recommendations of 2017
Germ testing papers
The testing papers do not contain any substances which could influence the growth of seeding. The colors used are non-toxic to germinating seed. The moisture level is maintained throughout the germination test period. The filter papers comply with ISTA and AOSA requirements.
