Learn more about how Whirl-Pak of Nasco Sampling got started

Did you know, the conception of Whirl-Pak® started with the need to collect liquid samples?

It all began with milk. In the early 1950s, milk was transported in bulk tanks after being collected from dairy farms along a specific route. With each farm’s product becoming combined in one blend, farmers soon began to voice concerns over the potential risk for a reduction in overall milk quality. Taking up the issue in 1954, Harold Barnum, a leading authority in the milk sanitation industry, developed a process called the “Universal Sampling Procedure.” With this method, a milk truck driver could collect milk samples from each farm and test it prior to transport in order to ensure its quality throughout the process. Because of the effectiveness of this testing, Barnum soon saw a need for mass production of leak-proof closure bags, and Whirl-Pak was officially established in 1959. Because Barnum transformed the dairy industry, he began to explore quality assurance testing and sampling in other industries, such as food, beverage, and water. Today we live in a safer, healthier world thanks to Barnum’s vision, and our business continues to thrive because of his tireless work.
