This is a modern tube in which Stuart salt is combined with the saliva of the patient. This Saliva Collection Tube allows you to collect and transport a patient's saliva sample for each test in the diagnosis of infectious diseases, genetic testing, or screening for drug use. The conforming tube can withstand rigors such as storage and slippage that occur during its usage. We barely use any printed materials on our tubes, so you can rest assured that the samples you receive remain uncontaminated. As a medical watchdog who is low on theatrics but high on innovation – we have superior products that add value to medical professionals and allow them to make important decisions quickly.
