Machined Piston pump
The 50xx series piston pump, developed by Keyto, offers high precision and repeatability in sampling and reagent addition, with a repeatability accuracy of less than 0.5% for displacements over 10%. Its transparent chamber design enables visual detection of internal bubbles, while its lifespan exceeds 5 million cycles. Covering a displacement range of 100 μL to 20 mL, it is a high-performance, maintenance-free pump widely used in chemiluminescence, biochemistry, POCT, and environmental analysis.
