Preventive maintenance keeps your equipment in proper working condition. When performed
routinely, maintenance results in longer life for your equipment. It also reduces time lost due
to equipment failure.
WARNING!
Always turn your BioFlo/CelliGen 115 off and disconnect the power cord
before performing maintenance.
16.1
pH Probe Maintenance and Storage
The pH probe should be stored standing upright, with the electrode tip immersed in a
solution of 3 molar KCl or a buffer solution between pH 4.00 and pH 7.00.
CAUTION!
Never let a pH probe rest on its tip.
Never leave a pH probe in DI water.
16.2
DO Probe Maintenance and Storage
Use soft facial tissue to clean the DO probe.
Check the probe’s Teflon membrane to be sure there are no punctures, puckers or
wrinkles. If there are, the probe should be replaced.
When it is not in use in the vessel, the DO probe should be stored standing upright
with the shorting cap in place and the membrane isolated from the air environment.
At no time should the probe be allowed to rest on its membrane.
CAUTION!
Never let a DO probe rest on its tip.
