The KP-11 series consists of 3 compact models of high accuracy / low pulsation dual piston pumps.

‘Current generation’ HPLC pumps use older technology involving rapid-refill cam design, pulse-dampeners, and preprogrammed pulse reduction patterns.  Unlike other pumps, the KP-11 offers an intelligent "self-learning", microprocessor-controlled, pulse-reduction feature that studies the pulse pattern at the initial stage and continually adjusts the motor speed until the pulsation is reduced to insignificance.  The result is amazing flow stability, ideal for today's demanding HPLC requirements.

Features:
•Microliter to semi-prep flow ranges available
•Dual-piston mechanism for steady solvent delivery
•Intelligent "self-learning" pulsation reduction feature
•Excellent Reproducibility (<0.3%RSD)
•Available in stainless steel or PEEK
•Simple operation, compact size (<3.5"W)
•External RS-232 control
•Internal method table retention and execution via RS-232.
