Frequently Asked Questions
1. How do I properly close a Whirl-Pak® bag to ensure a leak-proof seal?
To seal, simply whirl the bag three or more times around the wire closure and fold the wire tabs inward. This creates a secure, liquid-tight seal that can withstand the rigors of transport and shipping.
2. What is the purpose of the Thio-Bag®?
The Thio-Bag® is specifically designed for sampling chlorinated water. It contains a non-toxic tablet of sodium thiosulfate that instantly neutralizes chlorine, allowing for accurate microbiological testing of the water.
3. Can Whirl-Pak® bags be used for hot samples?
Standard Whirl-Pak® bags can withstand temperatures up to 82°C (180°F). For samples exceeding this temperature, it is recommended to allow the material to cool slightly before filling, or to use specialized high-temperature containers.
4. Are Nasco bags suitable for use in a blender or homogenizer?
Yes, Nasco offers a specific range of "Filter Bags" and heavy-duty bags designed for use in paddle-style blenders (Stomachers), featuring reinforced seams to prevent bursting during the homogenization process.
