Standard Bags
Whirl-Pak® Standard Bags are the original sterile closure bags, designed for routine sample collection, transport and storage. They are suitable for liquid and solid samples across food, environmental, industrial and laboratory testing applications.
Write-On Bags
Whirl-Pak® Write-On Bags include a white write-on strip for fast, clear sample labelling. They are ideal for workflows requiring traceability, sample identification and organised handling from collection through to analysis.
Stand-Up Bags
Whirl-Pak® Stand-Up Bags feature a gusseted base that unfolds when filled, allowing the bag to stand upright. They are ideal for liquid sampling, field collection and workflows where bottle-free, rack-free handling is preferred.
Thio-Bags®
Whirl-Pak® Thio-Bags® contain a sodium thiosulfate tablet to neutralise chlorine at the time of collection. They are designed for chlorinated water sampling, including potable water, wastewater, swimming pools and environmental microbiology testing.
Filter Bags
Whirl-Pak® Filter Bags include a full-page 330 µm filter layer sealed into the bag, allowing liquids to pass through while retaining larger solids. They are commonly used in food microbiology, blending, homogenisation and sample preparation workflows.
Sponge Bags
Whirl-Pak® Sponge Bags are designed for environmental monitoring and surface sampling. Available in PolySponge™, PolyProbe™ and Speci-Sponge® configurations, they support food safety, hygiene monitoring and microbiological testing workflows.
Black Bags
Whirl-Pak® Black Bags use opaque film to help protect light-sensitive samples during collection, transport and storage. They include a white write-on strip for sample identification.
Specialty Sampling Bags
Whirl-Pak® Specialty Sampling Bags are designed for specific market and application requirements, including food safety, poultry sampling and other specialised collection workflows.
