LSPone – Laboratory syringe pump

The pump that killed the dead volume

Spend more time on your microfluidic experiment and less on the hardware setup


The LSPone laboratory syringe pump is a high-precision dosing device for microfluidic applications. The high-accuracy dosing and nearly-pulseless flow stream capabilities make it the perfect tool for multiple liquid handling in the range of milliliter down to nanoliter.

The integrated zero dead volume selection valve allows you to handle multiple fluids with one syringe pump thanks to the high cleaning efficiency and low carryover. Coupled with its ease of use, the LSPone is thus the ideal companion for your laboratory experiments at a reduced investment cost.
