Quality Management, Inc. (QMI) is now QualiTru Sampling Systems

QualiTru Sampling Systems is the trusted partner for accurate, aseptic inline, or silo/truck fluid sampling for over 3 decades in over 28 countries. In 1983, after ten years with Ecolab, Darrell Bigalke, our founder, seized the opportunity to carry the QualiTru technology to support his dairy food safety consulting business. The aseptic sampling equipment proved its value, and the company has developed from a two-person operation to a growing niche business. Today, the same entrepreneurial spirit continues with the family business.

QualiTru supports a wide variety of industries that produce safe and quality products. QualiTru sampling systems are used in:

Applications include product quality verification across the supply chain, inline aseptic process verification; bulk tank and silo quality checks; and aseptic sampling for microbiological testing. We also offer unique sampling applications from mastitis management on farms to side-truck sampling for safe, antibiotic testing. Quality Assurance Managers and farms can confidently use the four-part aseptic system to help obtain an inline representative or silo sample.

QualiTru is driven to meet industry sampling needs while providing a family-friendly working environment. We do this by partnering with other subject matter experts (SME) and distribution partners to deliver the best sampling expertise to the dairy and other liquid industries.
