Seal washing prolongs the lifetime of the pistons and seals by preventing crystallization and particle deposits on the piston surfaces and seals. The flow path of the seal wash system passes through the metering device head in the autosampler and the pump heads in the pump. The seal wash system comprises the following parts:

  • In the pump: Seal wash pump (peristaltic pump), seal wash lines, and seal wash detector (drop detector)

  • In the autosampler: Seal wash lines

  • Reservoir for the seal wash liquid

The system is shipped with the seal wash components and lines installed.
