Cardinal Health Specimen Containers are designed for reliable and secure collection and transport of various biological samples. Their clear plastic construction, coupled with clearly marked graduations, allows for easy observation and precise measurement of contents. A highly visible "Positive Seal" indicator provides a clear visual confirmation that the container is securely sealed when its red bars are perfectly aligned. The exclusive metal lid, featuring a plastic lining, is engineered to create a leak-resistant seal, significantly minimizing the risk of specimen leakage during transportation. These containers are supplied sterile, ensuring aseptic conditions for specimen collection and protecting against contamination.
