WHIRL-PAK

The 25 mg active sodium thiosulfate tablet is included in WHIRL-PAK bags designed for chlorinated water sampling. Its purpose is to neutralize residual chlorine in the sample, which can otherwise continue to react with microorganisms and compromise the accuracy of microbial analysis. By neutralizing chlorine immediately upon sample collection, the tablet preserves the sample’s microbiological integrity during transport and until analysis. This feature is critical for compliance with standard methods for water testing, where residual chlorine must be quenched to obtain valid results. The tablet is pre-measured and placed inside the sterile bag, eliminating the need for separate reagent addition and reducing the risk of contamination. WHIRL-PAK bags with sodium thiosulfate are available in 4 fl oz (100 mL) capacity with a write-on labeling area, and they meet HACCP standards for food and water safety applications.

WHIRL-PAK stand-up sterilized bags are offered in a range of capacities to accommodate different sample volumes. The smallest standard size is 4 fl oz (118 mL), suitable for small liquid samples. Intermediate sizes include 18 fl oz (532 mL), 24 fl oz (710 mL), 36 fl oz (1.07 L), 42 fl oz (1.24 L), and 69 fl oz (2.04 L). The largest capacity available is 1.08 gallons (4.08 L), which is appropriate for bulk solid or semi-solid samples. These bags are self-standing, allowing them to remain upright during filling and handling. The clear construction enables visual inspection of the sample. Depending on the model, they may meet EPA, USDA, or HACCP standards, and some are made from FDA-approved materials. When selecting a capacity, consider the sample type, the required volume for analysis, and any headspace needed for mixing or transport.

Yes, WHIRL-PAK sampling bags are sterilized. The sterilization process is validated to ensure the bags are free from viable microorganisms at the time of use. Depending on the specific product, WHIRL-PAK bags may meet EPA, USDA, or HACCP standards. For example, some stand-up bags are manufactured to EPA standards for environmental sampling, while others meet USDA requirements for food safety or HACCP standards for food processing and water testing. Additionally, certain bags are made from FDA-approved materials, indicating they are suitable for contact with food and pharmaceutical products. The applicable standard is typically indicated in the product specifications. It is important to select a bag that meets the compliance requirements of your specific application, as standards vary by industry and regulatory framework.

WHIRL-PAK stand-up bags and write-on bags differ primarily in their physical design and intended handling. Stand-up bags are self-standing, meaning they have a gusseted bottom that allows them to remain upright on a flat surface without support. This feature facilitates hands-free filling and reduces the risk of spills during sample collection. Write-on bags, on the other hand, include a dedicated labeling area on the bag surface where sample information can be written directly. This eliminates the need for separate labels and helps maintain sample traceability. Both styles are sterile and made from clear polyethylene or FDA-approved materials, allowing visual inspection. Stand-up bags are available in capacities from 4 fl oz to 1.08 gallons, while write-on bags are often used for smaller volumes, such as the 4 fl oz chlorinated water sampling bag. The choice depends on whether hands-free filling or direct labeling is more critical for the sampling protocol.

WHIRL-PAK bags are designed for the collection, storage, and transport of both liquid and solid samples. The stand-up style is particularly suitable for semi-solid and solid samples because the bag can remain upright and accommodate larger volumes, up to 1.08 gallons. The clear polyethylene construction allows visual inspection of the contents, which is useful for confirming sample integrity. For liquid samples, the bags are leak-resistant and can hold volumes from 4 fl oz to over 2 liters. Some models include a sodium thiosulfate tablet specifically for chlorinated water sampling, but the general-purpose bags do not contain additives. When using WHIRL-PAK bags for solid samples, ensure that the bag capacity is sufficient and that the sample does not puncture the bag. The bags meet various standards such as EPA, USDA, or HACCP, depending on the model, making them versatile for environmental, food, and industrial applications.
