These sterile, polyethylene laboratory sample bags are available with or without a write-on strip. They are FDA-approved for food contact.
These 69-ounce Whirl-Pak® lab sampling bags feature patented puncture-proof closure tabs for worry-free collection and closing. Just tear off the top, pull the tabs to open, place or pour the sample in the bag, whirl it shut, and fold the wire ends onto the bag.
Whirl-Pak(r) polyethylene sample bags are sterile, inexpensive, and appropriate for liquid, semisolid, or solid samples. These 2.25-mil bags provide spill-free, reusable sample transport for general laboratory testing.
Puncture-proof tabs extend past the wire ends to eliminate sharp points that may puncture bags, scratch a person's hands or gloves, or cause damage to skin or products. To ensure safe and effective sampling, all Whirl-Pak(r) sample bags use this patented process.
These Vegas sample bags seal tightly to hold solids and liquids. Simply whirl the tabs three times and bend them over to lock the bag shut. The use of tape and double wireframes on both sides of the top creates a positive, moisture- and air-tight seal.

Transparent sample bags offer a cost-effective way to store liquids and powders. They are sterile, don't break, use a fraction of storage space, and reduce disposal costs.
These transparent lab sample bags are a great choice for sampling and product analysis. They are available with a write-on strip or without one for quick labeling.
To make them stay open, a combination of tape and double wire frames the top on both sides. Whirl the bag over the wire tape three times and bend the tabs over to lock shut to get a moisture- and air-tight seal.
These sample bags also have a unique puncture-proof tab. The tape on the tab extends past the wire ends, eliminating sharp points that could puncture a bag or cause injury to gloves and hands. These puncture-proof closure tabs are a safer and more convenient option than tamper-proof closures. They also allow samples to be added or removed from the bag without risk of contamination.

Non-Inhibitory Dry Sponge sterile sample bags, ready-to-use blue sponge swabs for sampling and microbiological assessment of a wide variety of surfaces. Manufactured from a special, bright blue, cellulose-based dry sponge that does not shed, these sampling bags are free of bactericides and have been tested to be non-inhibitory.
The non-inhibitory dry sponge swab is a natural cellulose that is dehydrated and packed inside an 18-oz Whirl-Pak Nasco sampling bag. It is available in both a premoistened and unmoistened form and is effective for the sampling of food surfaces and equipment, work areas, animal carcasses, and other surfaces that may be contaminated with microorganisms.
In the present study, we evaluated the antimicrobial activity and virulence of extracts from 14 different sponge species by testing them against the anti-virulence-potentiating isolate of the foodborne pathogen Corynebacterium violaceum (CV026). We compared the effects of extracts from wet and dry sponges, as well as semi-polar and non-polar extractions, on F. enigmaticus at early and non-target stages of development, like gametes and larvae.

The Speci-Sponge sampling bag from Nasco (B01245WA) is an environmentally friendly, non-inhibitory dry sponge that measures approximately 1 1/2 x 3 x 5/8 in. It is sterilized in a Whirl-Pak bag and is perfect for taking samples from the surfaces of work surfaces, equipment, and dead animals.
These samples are also convenient for a variety of microbiological tests and enumerations, including the detection of food pathogens. They can be used with or without a sterile glove and are available in different sizes.
The study showed that microbial enrichment significantly decreased the abundance and viability of many members of the initial bacterial community, with some OTUs even losing their presence in cultivation. This observation suggests that the in-situ microbial community was influenced by sample processing, a factor that has been largely ignored so far. In addition, the bacterial isolates recovered from sponge extract (SE) showed higher diversity than those recovered from isolation media alone. This was because some phyla, such as Gammaproteobacteria and Betaproteobacteria, were more common in SE isolates than in non-SE isolates. Another type of product on the market is the uline sample bags.
