Screenings and retention sieving tests are standard in our quality packages, but can be done as individual tests to confirm a dispute or assess a new size grading.

All testing is carried out in our TASCC accredited laboratory, and we are also a Licensed Seed Testing Station for certified seed. Click here to view the full range of testing and analysis options we have available.
