Overview
The document describes the neMIX stirring systems developed by cetoni GmbH, designed for precise and pulsation-free dosing of homogeneous suspensions in nanoliter scale. These systems are particularly useful for applications requiring controlled dosage of cell and particle suspensions into microfluidic devices or maintaining a constant concentration of a dosed mixture over time.

Requirements
1. Controlled dosage of cell and particle suspensions.
2. Constant concentration of dosed mixtures over time.

Solutions
The neMIX stirring systems are add-ons for the neMESYS syringe pump system, offering two solutions: the neMIX Syringe Stirrer and the neMIX Stirring Bottle.

neMIX Syringe Stirrer
- Consists of a stirring element with a permanent magnet inside a syringe.
- The rotating magnet mixes the suspension cautiously and stress-free.
- Benefits include pulsation-free dosage, adjustable stirring speeds, and compatibility with various syringe sizes (2.5 ml and 5 ml).
- Autoclavable for sterilization.

neMIX Stirring Bottle
- A closed vessel with a pendular stirrer and four fluidic connections.
- Ensures effective mixing and prevents sedimentation of particles.
- Provides stable concentration over time for reproducible chemical and biological processes.
- Benefits include pulsation-free dosage, adjustable stirring speeds, and flow rates in sub microliter scale.
- Autoclavable for sterilization.

Conclusion
The neMIX systems offer advanced solutions for precise and stress-free dosing of suspensions, enhancing the functionality of syringe pumps in various scientific and medical applications.
