Daisy Piston

The Daisy Piston is a state-of-the-art displacement pump designed for exceptionally precise and efficient fluid dispensing. It operates by moving a cylindrical shaft within the pump head — similar to a syringe pump. Valve timing at the ports controls fluid movement during aspiration and dispensing cycles.

Unlike a syringe pump, the Daisy Piston does not use an elastic sealing material at the top of the piston, dramatically reducing wear and tear. This design extends its lifetime by over two orders of magnitude compared to standard syringe pumps — up to 10 million dispensing cycles.

With 0.5% accuracy and <0.03% CV at full dispense volume, the Daisy Piston is our most precise pump. It is ideal for automated pipetting, long-term repetitive dispensing, and microfluidic flow control where precise flow stability is required — even with changing fluid viscosity or flow resistance.

The pump head is rated for 500 psi before leakage. For operations from vacuum up to 30 psi, use the integrated solenoid valves on either side of the pump head or optional Daisy Sol Val modules. For pressures between 30–150 psi, the Daisy Multi Valve modules are recommended.
