What is the use of saliva collector collection device?
DNA saliva collection is also known as genetic testing sampling, molecular diagnosis, disease screening, genetics, paternity testing, ancestral gene DNA, and other medical research units, genetic sampling popular saliva collector
Intended use: for the collection and room temperature preservation into the oral secretion of saliva samples. The sample is extracted and used for clinical in vitro diagnosis.
Collection principle: This product is used to collect saliva samples secreted into the oral cavity, and the collected saliva is evenly mixed with saliva preservation solution to ensure the integrity of DNA within the saliva samples and its long-term preservation under room temperature conditions.
Main components of the saliva collector.
1 collection funnel,
1 collection tube (with cap),
1 ml of saliva preservation solution.
Brief description of the saliva collector
1、Collection funnel and collection tube are combined and packaged together.
