BioCote Benefits
What is BioCote?
BioCote anti-microbial coating additive is present on all Stuart brand equipment and offers anti-microbial action to help prevent cross-contamination.
This unique additive is applied during the manufacturing process and contains trace levels of active silver ions which provide an effective anti-microbial action, active against many strains of common bacteria and fungi, including Aspergillus niger, E.coli and Listeria mono.
This coating remains active for the entire product lifespan and can actually help in prolonging the life of products, where a build up of microbes may cause premature material degradation.
BioCote works by inhibiting bacteria in a number of ways including protein damage, cell membrane damage, oxidative damage and DNA interference. Ultimately, the bacteria are prevented from replicating. Without this, bacteria have been shown to die naturally within around 8 hours. BioCote works in a way different to antibiotics so it is currently effective against antibiotic resistant strains.
More recently, BioCote technology was proven effective against particular virus strains, with a reduction of 90% in 2 hours against feline coronavirus, strain Munich. Read more here.
