Answer:The metering pump in compatible Shimadzu SIL-40-series autosamplers.
Answer:No. It belongs to the autosampler metering mechanism, not the main mobile-phase pump.
Answer:Priming, leakage and repeatable sample metering or injection performance.
The Shimadzu SIL-40 Autosampler Metering Pump Plunger Assembly is a mechanical replacement part for the precision liquid-metering pump inside compatible SIL-40-series autosamplers. The moving plunger helps displace a controlled volume of liquid during sample aspiration and injection preparation. Its surface condition and accurate movement influence metered-volume repeatability and normal operation of associated pump seals. Symptoms such as poor aspirating behavior, unstable metering or abnormal mechanical resistance may warrant inspection of the plunger assembly along with the seal and related pump head components. Before service, stop sample handling and solvent flow, release pressure and follow the metering-pump disassembly sequence. Avoid scratching the plunger or contaminating its sealing surfaces, then prime the autosampler and verify repeatable sample handling after replacement. The part is for the autosampler's metering pump, not the principal high-pressure mobile-phase delivery pump, its piston seals or an entire SIL-40 autosampler module.
Unless otherwise stated, the minimum order amount is USD 1,000.
