Ahlstrom seed testing papers are made of cotton linters and/or pure cellulose. They do not contain any substances which could influence the growth of seeding. The pH range is between 6.0 and 7.5 and the special structure prevents dine seed roots from growing through the paper.
A broad weight range enables the seed technician to maintain the required moisture level for the whole duration of germination test period.
The filter papers can be supplied in a variety of formats and are available in white and three shades of blue and yellow colored paper to make the evaluation of fine roots easier.
Our seed testing papers comply with ISTA (International Seed Testing Association) and AOSA (Association for Official Seed Analysis) requirements.
We offer various formats for each procedure:
- TP: Top of paper
- BP: Between the paper
- PP: Pleated paper
Customized shapes and sizes are available on demand.
