The Clipper Model 400 Office Tester & Cleaner offered by Seedburo is an extremely efficient cleaner for office and laboratory use. This machine will provide accurate, dependable performance for small lot cleaning, testing or sampling. It is commonly used in seed plants for sampling large lots of seed for correct screen selection on larger, commercial size cleaners. It is also widely used in university laboratories for agronomy research and testing and flower and vegetable growers use the Model 400 for specialized cleaning, grading and sizing.
