Product Overview

Cetoni Nemesys M is a high-precision injection pump with a medium pressure range, designed specifically for microfluidic applications that require pulse free, wide range flow control at higher pressures. Its core function is to stably transport fluids ranging from nanoliters per minute to milliliters per minute at pressures up to 200 bar through servo motors and closed-loop control algorithms.

core parameters(Typical value):

· Maximum work pressure：200 bar。

· flow range: Covering Na Sheng/Minutes (nL/min) to milliliters per minute (mL/min) level.

· Drive TypeServo motor paired with high-precision ball screw.

· Control method: Closed loopPID control ensures stable flow rate.

· Syringe compatibilitySupports glass, stainless steel, and heatable syringes with a variety of specifications.

Working principle and structural characteristics：
The pump uses a servo motor to drive a high-precision ball screw, which drives the syringe piston for fluid delivery. The key to its technology lies in high-resolution motor control and closed-loop controlThe PID feedback system can compensate for small positional deviations in real time, thereby eliminating pulsations caused by mechanical transmission at the sub micron level and achieving truly smooth liquid flow. The integrated aluminum casing provides high rigidity, ensuring mechanical stability under high pressure and avoiding flow fluctuations.

Advantages and Features

1. Pulse free transmission under high voltageAdopting servo motor closed-loop control and high-resolution driver, even inUnder a pressure of 200 bar, it can also achieve almost undetectable pulsating liquid flow, meeting the high requirements for flow stability in applications such as cell manipulation and chromatographic analysis.

2. Wide dynamic flow rangeA single device can cover from Na Sheng/Flow control ranging from minutes to tens of milliliters per minute reduces system complexity and errors caused by equipment replacement or different measurement ranges.

3. Modularity and high integrationDesign supports multiple pump module combinations and can easily integrate with the company'sIntegrate Qmix valves, mixer modules, and automation platforms (such as robotic arms) to build complex multi fluid processing systems.

4. Integrated software control: Equipped with dedicatedQmixElements graphical control software supports process programming, real-time pressure/flow monitoring, and provides programming interfaces such as LabVIEW and Python for easy integration into automated experimental platforms.
