Sterilised by ethylene oxide, Deltalab’s Sterile Human DNAse, RNAse and DNA Free Certified Swabs are supplied in a polypropylene tube, which protects the sample up to the laboratory prior to their analysis.
The stick of the swabs are made of polystyrene while the head is produced with viscose.
The tubes are labelled indicating the code, description, lot, expiry date and providing an identifying area to note down collection details (site, date, etc.).
Moreover, the labels seal the tubes with the cap of the swabs, acting like a tamper evident system.
