For an easy way to collect a sample of a dry product, try the new Whirl-Pak® Spoon Bag. An 18 oz. (532ml) write-on bag contains a sterile, disposable plastic spoon of approximately 1 tsp. capacity. Minimize possible contamination by opening only one package instead of two when collecting the sample. It is ideal for a wide range of dry products, powders, and other similar materials. Box of 100. Sterile items are non-returnable.
