Whirl-Pak® Stand Up Bags

select option

Available in 7 sizes.

Accessory for use with magnetic stirrers and stirring drives; liquid, semi-solid, and solid samples; and much more.

Sample handling and testing is easy with disposable Whirl-Pak® Stand-Up Bags, first sterile sample bags on market. When filled with sample, special gusseted bottoms flatten out, allowing Whirl-Pak® Stand-Up Bags to stand on their own. No racks or other holders are necessary to keep Whirl-Pak® Stand-Up Bags upright. Work just like other containers but are cost-efficient, space-saving, and shatterproof. Add a stirring bar and use with a magnetic stirrer. Use a single sample for all required quality control, product content, and legal compliance tests. White write-on strips make sample identification convenient. Can be frozen to any temperature, even liquid nitrogen temperatures (careful handling required after freezing; sample bags are not autoclavable). For use in temperatures from -210° C (-346° F) to +82° C (+180° F). Sterilized after manufacturing. FDA approved for food contact. Manufactured in accordance with requirements for manufacturers of single service containers for milk and milk products, as specified by FDA. Capacity measured in fluid ounces when closed and tabs folded over 3 times. Film thickness varies from 2.5 mils to 4 mils, depending on size. As a result of high-quality blended polyethylene, a high mil thickness is not required to achieve optimum strength. Manufactured under a quality management system certified to ISO9001. See Specifications for technical details and additional information. 

Features Include:

  • Puncture proof tabs—tab tape extends past aluminum wire ends to eliminate sharp points that could puncture sample bags and gloves or scratch hands.
  • Guaranteed sterile—sealed cartons sterilized with +1 sterilization process after manufacturing using ethylene oxide gas at an independent ISO certified facility.
  • Exceptionally clear film and superior strength—manufactured with co-extrusion of low-density and linear low-density virgin polyethylene (LPDE) making sample bags easy to see through and durable sample containers.
  • Leak proof closure—whirling or folding tabs over 3 times creating leak-proof sampling containers.
  • Reduced storage and shipping—saves 90% more space than other containers, which significantly reduces shipping, storage, and disposal costs.
