Chlorhexidine Gluconate 20% is microbial free.
Microbials are extremely resistant to even the harshest and most unlivable conditions.
The so called extremophiles (extremophilic microbials) live in habitats which for other terrestrial life-forms are intolerably hostile or even lethal. Some live in extreme hot niches, ice, and salt solutions, as well as in acid and alkaline conditions. Some may grow in toxic waste, organic solvents, heavy metals, or in several other habitats that were previously considered inhospitable for life.

So it is not surprisingly, that even in a medium that is used as a disinfectant, microbials can life and grow.
RN Laboratories is aware of those specific microbials. Contamination is prevented by
- own in house production in dedicated plants under controlled atmosphere
- strictly use of purified water only
- release of all batches only after a validated microbial test.
