this chapter describes actions that should be performed on a routine basis to ensure the
long term safe and trouble-free operation of the PLC Purification System. the frequency of
the maintenance activities is dependent on the nature of the application, such as the solvents
used, the volume of the mobile phases delivered by the pump, the level of cleanliness of
the facility, etc. the system has been designed for reliability and needs very little routine
maintenance when operated correctly.
When performing the maintenance described in this chapter, use good laboratory
practice (GLP), including, but not limited to, wearing protective clothing and preparing the
maintenance space for service. after completing the maintenance operation, verify the safe
and good working order of the part and instrument.
three models of pump are available in the range (50 mL/min, PLC 2050; 250 mL/min,
PLC 2250; and 500 mL/min, PLC 2500). Parts of the heads kit are different according to the
pump model (seals, pistons, cleaning discs, heads, etc.).
reduced accuracy of the pump may be caused by seal wear or to a fault in the check valves.
