The advantages of Flow Systems?
Flow processes replace traditional batch methods with continuous, precisely controlled fluid flows.
The result: stable conditions, reproducible reactions, and greater process reliability.
CETONI’s Nemesys syringe pump systems provide the technological basis for this:
+ Pulsation-free flows for homogeneous reaction conditions
+ High-precision volume control even at minimal flow rates
+ Synchronized multi-channel control for complex fluidic setups
+ Stable, continuous delivery over extended operating periods
+ Modular system design from laboratory testing to process integration
Whether microfluidic droplet processes, continuous reactors, or highly selective cell and material applications –
CETONI syringe pump systems enable precisely defined, reproducible flow conditions instead of variable batch results.
Why pulsation-free?
Microfluidics works with the smallest flows in tiny cavities. For applications such as flow chemistry and biochemistry, uniform, pulsation-free liquid flows are crucial to ensure constant mixing ratios and precise flows.
Pulsations are fluctuations in the flow rate that can be problematic with extremely small flows in microfluidics. Absolute freedom from pulsation is not technically possible, but we can reduce the pulsations to such an extent that they no longer have any measurable effects.
We use high-quality components and precise drives in our syringe pumps to reduce pulsations to a minimum. As a result, our Nemesys syringe pumps provide the extreme accuracy and stable conditions required for microfluidic applications.
Microfluidic applications where pulsation-free dosing is crucial:
Biology: When analyzing and sorting cells, the creation of single-cell analyses requires a constant and pulsation-free flow in order to precisely manipulate and examine the cells.
Chemistry: In flow chemistry, a uniform flow rate is crucial for the reproducibility of reactions and the precise control of mixing ratios, leading to consistent and reliable results.
Industry: In the production of microstructured materials and sensors or homogeneous layers, liquids must be dispensed precisely and evenly to ensure the desired structure and functionality.
