The Tank Yank is an accurate, safe and productive device to collect representative samples from any sized container. Tank Yanks were developed through the collaboration of professionals annoyed with the inefficiencies of traditional sampling techniques. Irrespective of operator aptitude, stature and workplace controls or environmental factors, the sampling process is uniform and consistent. Sampling is simple: Just lower the sampler into the material to be sampled, engage the plunger to secure the core, and finally retrieve the plunger to transfer the material directly into a sample jar.
