Seed testing papers, grade 181, Whatman™

Grade 181 support filter for seed tests using copenhagen tank system.

• Extremely high purity
• Reliable and reproducible results

The papers are made from pure cellulose without any additives and do not contain any substances that could influence the growth of the seeds. The constant water absorption of the papers ensures the continuous provision of the required amount of water.

The better contrast of the color seed testing papers makes evaluation easier, particularly for seeds with fine white rootlets or under artificial light. This makes work easier, improves the results, and saves time. The dyes that we use have been thoroughly investigated and have no influence on the growth of the seeds.
