Ahlstrom's seed testing papers are specifically designed for the seed industry and agricultural research labs, focusing on providing a non-toxic environment that supports optimal seed germination and root development. These papers are crafted from cotton linters or pure cellulose, maintaining a neutral pH range of 6.0 to 7.5, ensuring that they won’t interfere with seed growth. Their special structure prevents fine seed roots from embedding in the paper, which is essential for maintaining sample integrity.
The papers are available in a variety of weights to help seed technicians control moisture levels across the germination period. For ease of assessment, Ahlstrom provides these filter papers in white and colored options, including shades of blue and yellow, enhancing the visibility of fine roots. The seed testing papers meet ISTA (International Seed Testing Association) and AOSA (Association for Official Seed Analysis) standards, making them reliable for professional use.
Ahlstrom offers formats suited to different testing methods:
- TP (Top of Paper): For placing seeds on top.
- BP (Between Paper): For enclosing seeds between layers.
- PP (Pleated Paper): For maximizing space in germination tests.
Custom shapes and sizes are available upon request, allowing labs to tailor the products to specific testing needs.
