Labplas TWIRL'EM Clear bags are clean, single-use, fully transparent sampling bags for collecting, transporting and storing liquid, semi-solid and solid samples. The clear film lets you see the sample without opening the bag, and the built-in wire closure seals it waterproof and airtight with a simple twirl and fold.
This page covers seven Clear sizes with the standard 2-round-wire closure, from 3.5 × 7 in to 7 × 12 in, including a heavier 4 mil 7 × 12 in bag. They're used in food and beverage QA/QC, wastewater and environmental labs, agriculture, research laboratories, and universities and colleges. TWIRL'EM bags are available in Canada from Cambridge Environmental Products with CAD pricing and Canadian purchasing support.
Labplas produces TWIRL'EM bags with dry heat during film extrusion (above 220 °C / 428 °F), which its data sheet rates at a sterility assurance level (SAL) of 10⁻³. Labplas also lists them as DNase-free, RNase-free and non-pyrogenic. These bags are not irradiated and are not supplied with a sterility certificate. If your procedure requires certified sterile bags, choose TWIRL'EM Clean Room.
The fully transparent film, with no printing, gives a clear view of the contents for visual checks, and leaves the whole surface free for your own labels.
Twirl the bag by the wire ends to wind the top closed, then fold the wires over to lock it. The sample is sealed waterproof and airtight for transport, without caps, clips or heat sealers. A tear-off perforated top keeps the opening clean until you sample.
The polyethylene-blend film meets FDA 21 CFR 177.1520 and EU Regulation No 10/2011 for food contact, according to Labplas. That matters when bags hold food samples or product destined for testing.
Labplas lists a 5-year shelf life when stored dry at room temperature, so cases of 1,000 can be kept on hand without waste.
All Clear bags on this page use the standard closure (2 round wires). Choose the size in the selector. Need a printed writing area or a heavier closure? See TWIRL'EM Write-On. For controlled environments, see TWIRL'EM Clean Room.
