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 temperatures down to -346° F (-210° C) - careful handling required after freezing. All bags are sterilized after manufacturing.
