OEM SPM Sequential Microdispenser

The all-in-ONE sample manipulator

Handle delicate samples with great precision

This is an OEM product. It can be tailored for the needs of your instrument.


Our OEM sequential microdispenser is a high-precision dosing device for automated 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, this syringe pump is thus the ideal companion for your instruments and laboratory experiments at a reduced investment cost.
