Whirl-Pak Sampling Bags

Whirl-Pak Sterile Sampling Bags are strong, sterile, and leakproof. Made of polyethylene, they are designed to carry solids or liquids to a laboratory for testing. All bags feature puncture-proof tabs, which means the tape on the tab extends past the ends of the wire covering the sharp points. This protects the user’s hands and gloves, as well as the bag, from puncture. The bags are sterilized with ethylene oxide gas, so each bag is completely bacteria free. Use the bags once, and then dispose of them. They are economical, easy to use, and take up very little space. Unlike glass bottles, they are unbreakable, which means easier handling for milk haulers and laboratory technicians. To close, simply whirl the bag three or more times and bend the tabs onto the bag. No need to keep track of covers, the bags can be opened and closed as often as necessary.

Write-On Whirl-Pak® Bags make sample identification easy! Designed with a white write-on strip that can be written on with an ordinary ballpoint pen or pencil. No labels to come off! Ideal for milk, water, and food sampling.

Flat Wire Whirl-Pak® Bags made with one flat wire, rather than the traditional round wires. The flat wire provides a thicker tab, resulting in a heavier closure which is preferred in some applications. The aluminum wire features PUNCTURE PROOF TABS, so the wire ends are completely covered, eliminating any sharp, cutting, exposed edges. The aluminum will not rust when coming in contact with water or other liquids.

Bags for Stomacher Lab Blenders have a white, write-on strip to make 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.
