Screw Cap Containers

Screw cap containers are fundamental specimen collection supplies engineered to securely hold biological fluids and other sample types throughout collection, transport and laboratory processing. These containers feature a precision-threaded screw cap that provides a reliable, leak-resistant seal to prevent spills, preserve sample integrity and reduce the risk of contamination or degradation during handling and shipping. Many options include molded graduations for accurate volume measurement and areas for patient identification, supporting compliance with specimen handling protocols and regulatory requirements such as DOT drug testing standards. Whether for routine urinalysis, toxicology screening or general clinical specimen collection, high-quality screw cap containers deliver the durability and performance needed in healthcare, diagnostic and laboratory environments.
