This FDA-listed collection and transport system provides organism viability for up to 72 hours at room temperature. The disposable culture tube can hold up to 10 mL, is 95 kPa IATA packaging instruction 650 compliant, and is made of 100% polypropylene, making it virtually shatterproof. It also comes with a CQ-Lock™ screw cap, which prevents leaks, even in pneumatic tubes. The 153-mm CavSwab Nasopharyngeal flocked swab with a 101.3-mm breakpoint and Allium™ flock technology has been engineered with a precision scalloped surface to produce “cava.” This design creates a greater surface area to absorb and help collect larger amounts of the specimen. Allium flock technology refers to the unique ability of the nylon fibers which are attached with medical-grade nontoxic water-based glue to adapt to the direction the swab is being pushed/pulled, resulting in less friction and an overall more pleasant experience for both the medical professional and the patient.
