Whirl-Pak® Stand-Up Bags

The Whirl-Pak Stand-Up Bag makes sample handling and testing much easier because it gives users the ability to perform important laboratory functions with both hands, as the bag will stand completely by itself. No rack or other holder is needed to keep the bag upright. When the sample is placed inside, the special gusseted bottom flattens out, allowing the bag to stand up on its own. It works just like a beaker or bottle, however, it costs less, is sterile, won't break, and uses only a fraction of storage space as other containers.

The white, write-on strip makes sample identification easier and more convenient. It's easy to write on this white strip using an ordinary ballpoint pen, pencil, or felt-tip marker. The paper-like finish virtually eliminates ink smearing and provides a surface that will accept a variety of writing instruments.
