The following parts will be checked regularly (during yearly PM) in order to maintain systems functionality. But the user itself can also keep the system tidy with a little effort.
During the system usage the needles will be cleaned and washed regularly, but at the outer surface there could be buildup of salt-crusts.
Note: Clean off the salt-crust using a lint-free tissue and ddH2O.
While system usage the syringe pumps can become leaky, thus salt-crust could build up over time.
Note: Clean off the salt-crust using a lint-free tissue and ddH2O. Replace Teflon plunger, if needed.
While usage or if system is longer idle microbiologic growth could have been build up. Also protein residuals could have been adsorbed to tubing and microfluidics. In order to clean the whole system, cleaning routines like Desorb, Sanitize or Super Clean can be performed.
To proof systems functionality please run test injections after the cleaning to check systems functionality. Choose all spot-addressing to verify the functionality and run the injections in multiple repeats.
