Nasco Whirl-Pak B01365WA Stand-Up Bag, 23cm L x 11.5cm W, 532 ml Capacity (Box of 500)

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, 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 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 storage space as the other containers.

• The white, write-on strip makes sample identification easier and more convenient.
• 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.
• Bags should not be used at temperatures above 180° F (82° C).
• Bags can be frozen to any temperature
