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.
CETONI uses high-quality components and precise drives in our syringe pumps to reduce pulsations to a minimum. Our Nemesys syringe pumps therefore offer the extreme precision 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.
The high-precision and pulsation-free dosing of liquids on a micro and nanoliter scale places the highest demands on the pump technology used. In the field of biology and biochemistry, it is not a question of high pressures, but rather a very homogeneous flow behavior, even at the lowest flow rates, as well as a quick response to changes in flow rates. We have optimized these core properties in our CETONI Nemesys S and M syringe pumps so that you can easily achieve perfect results.
Many fluidic processes that were conventionally carried out in batch processes, can be converted into progressive flow processes, and offer a number of advantages over conservative approaches, such as high process reliability, homogeneous reaction conditions, as well as time and resource savings. The areas of application extend from biology to chemistry to physics in different application scenarios, which we have clearly described for you under Application Notes.
We will show you how you can convert your batch process into an advanced flow process or how to automate laboratory processes that were previously manual with the help of Cobomation. Just talk to us!
Based on the feedback from our customers and our experience, together with the know-how of our partner SETonic GmbH (Ilmenau, Germany), we have developed a reliable and easy-to-use precision syringe series that optimally suits our products and the requirements of our customers.
