Sterilizing the plumbing of the FORMULATOR is recommended to prevent microbial growth. You should run the sterilization process every two weeks if the FORMULATOR is idle for long periods. If you use the FORMULATOR daily, run the sterilization process once per month.
At least one reagent bottle is attached to the FORMULATOR. This is required because you cannot run a bottle input wash without at least one bottle attached to the FORMULATOR.
Prepare a 5-10% bleach solution and attach it to the secondary wash input. If you do not have secondary wash input, remove the water carboy attached to your wash line input. Empty the carboy, and fill it with 5-10% bleach solution.
Run an internal wash cycle by going to the Device menu and selecting Internal Wash.
Run an external wash cycle by going to the Device menu and selecting ExternalWash.
Run an input wash cycle by going to the Device menu and selecting Wash All Inputs.
Let the FORMULATOR sit for 5-10 minutes to allow the bleach to sterilize the plumbing.
Repeat each of the bleach wash cycles 2-3 times.
Follow one of the procedures:
If you DO NOT have a secondary wash line, dispose of the rest of the bleach solution according to your lab's safe disposal procedures. Fill the carboy halfway with water, replace the septa cap, and shake vigorously to remove any traces of bleach from the carboy. Dispose of the rinse solution and rinse the carboy again. Then, fill the carboy with deionized water and attach it to the FORMULATOR.
If you have a secondary wash line, you may leave the 5-10% bleach solution attached to the FORMULATOR, or replace it with the solution you use as your secondary wash.
Run 2-3 water rinse cycles through each wash system (internal, external, input) to remove any traces of bleach from the FORMULATOR.
Your FORMULATOR is now ready for dispensing.
