The safe, easy and more reliable way to test grain.

U.S. Patent 6532836

Welcome to BIO-TAP

BIO-TAP is a grain bin sampling port that provides easy access and more reliable testing of the grain in bins. Through its patented design, BIO-TAP does not compromise the integrity of the bin and it protects against weather, disease and insects.

BIO-TAP is the only grain storage device that allows for safe, easy and effective grain sampling throughout the bin - regardless of internal height of the stored grain.

BIO-TAP can easily be installed on any grain bin by the "Do-It-Yourselfer" and accepts a standard grain probe.

BIO-TAP allows you to verify the quality of the grain right on the farm so you know what to expect when grain is delivered to be sold, eliminating surprises.

BIO-TAP is the safe, easy and more reliable way to test grain.
