Basically, it should be noted that within one and the same interchangeable unit only the specified cylinder size
may be installed, since otherwise the coding which is memorised within the interchangeable unit will no longer
match the cylinder size. This will entail incorrect dosage. And for the sake of dosing and analytical accuracy, it is
also recommended to replace the PTFE pistons each time a defective glass cylinder is replaced. This applies in
particular to glass breakage, since broken glass may damage the sealing rings of the PTFE piston.
Please note: As a rule, the hoses and cylinders will contain chemicals which may spill or be splashed around in
the course of disassembly. The relevant safety precaution measures applicable to the handling of the chemicals
concerned have to be observed.
