Borner Divider
Precision sample dividing equipment designed to split grain and seed samples into uniform, representative portions for accurate laboratory analysis.
What is Borner Divider?
The Boerner Divider is an industry-standard, gravity-operated sampling device utilized in agricultural laboratories and grain inspection facilities to reduce bulk seed lots into smaller, statistically accurate samples for analysis
When raw material is released from the top hopper, it disperses uniformly over the cone, dividing the stream into two independent channels that discharge into separate collection pans.
This equipment is a critical asset for quality control and procurement; it completely eliminates human bias and mechanical error from the sampling process, ensuring that subsequent moisture, purity, and grading tests are performed on a perfectly representative cross-section of the entire agricultural lot.
Common Applications
Grain Inspection & Grading Centers
Crucial for preparing unbiased, legally compliant sample splits for official regulatory grading and export certification.
Commercial Seed Conditioning Plants
Used to reduce bulk harvested lots into accurate laboratory-sized fractions for purity, viability, and germination testing.
Rice & Grain Milling Facilities
Essential for obtaining uniform representative samples from incoming truckloads or railcars prior to processing.
Agricultural Research & Breeding Stations
Providing precise fractional divisions of rare or experimental seed varieties without risk of cross-contamination or mechanical damage.

Gravity-Driven 50:50 Splitting
Operates purely via gravity without the need for electrical power, ensuring entirely uniform distribution. The material splits into two identical halves with zero mechanical heat or force exerted on the seeds.
Anti-Static Brass Construction
Fabricated entirely from premium, non-magnetic brass or polished copper to eliminate static electricity buildup. This prevents lightweight chaff, dust, and fine seeds from adhering to internal surfaces, ensuring a complete cleanout between batches.
Symmetrical 38-Pocket Cone
Features a precision-engineered internal dividing cone surrounded by 38 exactly uniform slots. This high pocket count maximizes sampling randomness and guarantees compliance-grade, representative divisions every time.
