Specimen containers are sterile, leak-proof systems essential for safe collection, transport, and storage of biological samples like urine, blood, stool, and tissues in clinical, diagnostic, and research settings. Crafted from durable polypropylene or polystyrene with secure screw caps and integrated labels, they prevent contamination and comply with UN3373 regulations for infectious substances. Available in volumes from 10ml to 500ml, including pediatric sizes and preservative-filled options, these containers feature graduated markings, tamper-evident seals, and color-coded caps for easy identification. Designed for single-use, they minimize biohazard risks, ensure sample integrity during lab analysis, and support efficient workflows in hospitals, clinics, and pathology labs worldwide.
