What is biofilm?

Biofilms are microorganisms that can grow on many different surfaces. Microorganisms that form biofilms include bacteria and fungi. Biofilms thrive in wet environments.

Over the course of regular use, waterlines and connected devices such AW syringes can build up biofilms which contaminate the water which flows through them.  The result of this can be healthcare acquired infection.
