FAQ: How to clean ViVitro equipment

Clean ViVitro equipment helps your system last longer, reduces wear and tear, and improves visibility. We recommend  adding a biocide Cosmocil QC (Biguanide 20) or Proclin to your testing solution to reduce the bioburden impact of contamination and extend the life of your system. ViVitro uses Biguanide 20 and use one drop per litre of fluid. Please use supplier concentration recommendations if you choose to use Proclin.

Test fluid should be replaced when bio-film contamination compromises visibility (in general, replace the hydraulic fluid every 2 months). If the system is not being used for extended periods, it should be drained, all components cleaned with a soft cotton cloth and detergent, and then dried before storage.

Acrylic parts can be cleaned using a soft cotton cloth with detergent and water making sure that the water is hot (approximately 45 degrees Celsius). After cleaning, flush with fresh water several times to remove any soap residue. If required, acrylic parts can also be sterilized using an appropriate sterilizing agent. To sterilize the system, soak the components (other than stainless steel) in a light bleach solution, then wash everything with Alconox or Actril. These are mild detergents which leave no residue and are safe on all components of the system.

NOTE: Alcohol, abrasives and solvents should never be allowed to come into contact with the acrylic components of the Model Heart.

Keep sterilizing agents away from any flow probe electrodes. Sterilizing agents may damage electrode surfaces.
