When you need to collect a sample of milk, feed, soil, or just about anything else. Whirl-Pak® sample bags are strong, sterile, and leak-proof. 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 with 500 in a box, 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.
- 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 82°C (180°F). Bags can be frozen to any temperature, including liquid nitrogen temperatures down to -210°C (-346°F) - careful handling required after freezing.
- All bags are sterilized after manufacturing.
