Would you like to have both hands free when working with a sample bag? The Whirl-Pak^® Stand-Up bag gives you the freedom to perform important laboratory functions with both hands, because it will stand up completely by itself. No rack or other help 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 sterilized, won’t break, and uses only a fraction of the storage space used by most other containers. Has a convenient write-on strip for easy sample identification.
