Swabs are Sterilised by radiation. Swab: CE MDD Class IIa. Tube: CE IVD. The modified Stuart media allows the conservation and transportation of a large number of pathological microorganisms, such as: Neisseria gonorrhoeae, Haemophilus influenzae, Neisseria meningiditis, Bordetella pertusis, Corynebacterium diphteriae, Trichomonas vaginalis, Staphylococcus aureus, Streptococcus sp., Salmonella sp., Shigella sp., etc. The most unstable organisms will remain viable for up to 24 hours and other for several days. The media is reduced due to the presence of thioglycolate, which difficults the enzymatic reactions of the bacteria. The multiplication of the bacteria is prevented due to the lack of nitrogen in the media. Dimensions of tube: 165x13 mm. PS shaft: 150x2.5 mm. Tip D=5 mm. Expiry date: 30 months from Sterilisation date.
