Bags

Sample collection bags are a foundational consumable for environmental field sampling, food safety testing, microbiological analysis, and industrial hygiene programs where the integrity of the sample from collection point to laboratory must be guaranteed by the container itself. Unlike rigid vessels, flexible sampling bags conform to irregular collection geometries, allow for direct stomaching and homogenization without transfer steps that introduce contamination risk, and offer a closed-system collection format that minimizes handling exposure for biohazardous and regulated matrices. The bag material, closure mechanism, and sterility status must be matched to the collection method and downstream analysis — a standard polyethylene bag is appropriate for inert bulk material sampling, while a sterile Whirl-Pak or TWIRL'EM format is required for microbiological chain of custody, and an autoclave bag must be rated for the temperature and pressure cycle of the sterilization process it is designed to withstand.

Ibis Scientific stocks a comprehensive range of laboratory and field sampling bags to support environmental, food safety, clinical, and industrial applications. Our selection covers autoclave bags for biohazardous waste containment and sterilization cycles, biohazard bags for regulated waste collection and transport, filter bags for stomacher-based homogenization of food and environmental matrices, standard polyethylene bags for bulk and inert material sampling, sterile sampling bags for microbiological specimen collection, TWIRL'EM opaque bags for light-sensitive samples, and Whirl-Pak bags for field collection and chain-of-custody microbiological sampling. Options are available across a range of capacities, film thicknesses, and closure styles to match collection volume and handling requirements.
