Enjoy the ease of working with your samples in a Whirl-Pak® Stand-Up Bags for Sterile Sampling that stands upright by itself. A special gusset creates a flat bottom when the sample is placed in the bag, allowing the bag to stand completely on its own. May be used to hold liquids or solids. Available in 4 oz – 138 oz sizes. Pack of 500 bags.

The Whirl-Pak® Stand-Up Bag makes sample handling and testing much easier, giving users the ability to perform important laboratory functions with both hands, because 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 Stand-up Bags 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 storage space as the 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.

Capacity is measured in fluid ounces when the bag is closed, and tab is folded over three times. Volume and dimensions are approximate; bags should not be used at temperatures above 180° F (82° C). Bags can be frozen to any temperature, even liquid nitrogen - careful handling required after freezing. All bags are sterilized after manufacturing.
