KP HPLC Pumps

Binary (Dual Piston) Pump KP Series for HPLC and Flow Chemistry

The KP dual piston pumps provide stable flow comparing to single piston. Three types of piston replacement volumes cover the flow rate range of 0.1 µL/min to 50.0 mL/min.  Small foot print represents the technology inside products. A pressure sensor and limiter equipped for the KP-22. The affordable KP-21 does not have the pressure sensors. The washing port behind the piston seal extends the useful lifetime of the piston seal. Salts derived from mobile phase are removed by passing water through the pass ports.

Directly controllable from the front key-panel without add-ons. Also controllable through built-in communication board with the 3rd party softwares.
