WHIRL-PAK

WHIRL-PAK, a brand of Nasco, has been a manufacturer of sampling bags and laboratory equipment since its founding in the 1940s. The brand is recognized for its focus on sterile and non-sterile sampling solutions used in environmental, food safety, and industrial applications. 3G Electric supplies a range of WHIRL-PAK products, including standard and self-standing sterilized sampling bags, write-on bags for sample identification, and components for the Sludge Judge lab dipper system. The product line covers capacities from 24 fl oz (710 mL) to 123 fl oz (3.64 L) for bags, and dipper components such as bottom sections, extension sections, and valves in materials like plastic and polycarbonate. WHIRL-PAK bags are available in clear or with black write-on panels, and are certified to standards including USDA, EPA, and HACCP, depending on the specific SKU. The Sludge Judge dipper components are pre-cleaned to visible particulates level, suitable for non-sterile sampling of liquids, sludges, and solids. 3G Electric stocks over 50 SKUs of WHIRL-PAK products, providing datasheets and logistics support for global procurement. The brand’s emphasis on reliable, single-use sampling reduces cross-contamination risk in field and lab environments. For engineers and procurement specialists, WHIRL-PAK offers standardized solutions for water quality testing, food processing checks, and industrial hygiene monitoring. The bags feature a tear-away tab for easy opening and a wire closure for secure sealing. The Sludge Judge system allows customizable dipper lengths via modular sections, with capacities up to 445 mL per section. All products are manufactured under ISO 9001-certified facilities, though specific certifications per SKU vary. 3G Electric’s inventory includes both sterile and non-sterile options, with sterile bags gamma-irradiated to ensure microbial integrity. The write-on bags incorporate a frosted panel for permanent marker labeling, aiding traceability in compliance with regulatory protocols. For industrial buyers, WHIRL-PAK products are designed for single-use disposal, reducing cleaning costs and sample contamination risks. The brand’s long history in sampling technology ensures consistent quality across batches, with each lot traceable via manufacturing codes. 3G Electric supports these products with technical specifications, dimensional data, and compliance documentation to facilitate integration into existing sampling protocols.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang WHIRL-PAK dari 3G Electric.

What are the key differences between WHIRL-PAK standard and self-standing sampling bags?

Standard WHIRL-PAK sampling bags are flat-bottomed and require a rack or holder for upright use, while self-standing bags have a gusseted bottom that allows them to stand without support. Both are sterile and available in various capacities. Self-standing bags are typically used for sample collection in the field where a flat surface is available, whereas standard bags are more compact for storage and transport. The choice depends on the sampling environment and whether hands-free operation is needed.

Are WHIRL-PAK write-on bags suitable for labeling with permanent markers?

Yes, WHIRL-PAK write-on bags feature a frosted, matte panel specifically designed for writing with permanent markers, ballpoint pens, or pencils. The panel accepts ink without smudging, allowing for clear sample identification, date, and other data. This is critical for traceability in food safety and environmental testing. The write-on area is located on the front of the bag, away from the sample compartment, to prevent contamination.

What standards do WHIRL-PAK sampling bags comply with?

WHIRL-PAK sampling bags are manufactured to meet various regulatory standards depending on the SKU. Common certifications include USDA (United States Department of Agriculture) for food contact, EPA (Environmental Protection Agency) for water sampling, and HACCP (Hazard Analysis Critical Control Point) for food safety protocols. Each bag's packaging or datasheet specifies the applicable standard. The bags are also gamma-irradiated to achieve sterility, ensuring compliance with microbiological testing requirements.

How does the WHIRL-PAK Sludge Judge system work for liquid sampling?

The Sludge Judge system consists of modular sections—bottom section with valve, extension sections, and top section—that can be assembled to reach desired depths. The bottom section has a one-way valve that opens when lowered into liquid, allowing sample entry, and closes when lifted to retain the sample. Each section has a 445 mL capacity. The system is non-sterile and pre-cleaned to visible particulates level, suitable for sludge, wastewater, and industrial fluid sampling. Components are available in plastic or polycarbonate.

Can WHIRL-PAK bags be used for autoclaving or high-temperature applications?

No, WHIRL-PAK sampling bags are not designed for autoclaving or high-temperature use. They are made from low-density polyethylene (LDPE) or linear low-density polyethylene (LLDPE), which have melting points around 105-115°C. The bags are intended for ambient temperature sample collection and storage. For high-temperature applications, alternative materials like polypropylene or PTFE bags should be considered. Always check the product specifications for temperature limits.

What is the shelf life of WHIRL-PAK sterile sampling bags?

WHIRL-PAK sterile sampling bags have a typical shelf life of 5 years from the date of manufacture when stored in original packaging at room temperature (15-30°C) and away from direct sunlight. The sterility is maintained by gamma irradiation and sealed packaging. After the expiration date, the sterility cannot be guaranteed, though the bags may still be usable for non-sterile applications. Each bag's lot number and expiration date are printed on the packaging for traceability.
