Syringe Stirrer neMIX

Pulsation-free Dosing of homogeneous Suspensions

Preventing Sedimentation through gentle Stirring

In some applications it is necessary to ensure the gentle mixing of substances or to keep the concentration of mixed substances nearly constant over a certain amount of time during dosing and to prevent sedimentation.

There is a solution for both of these scenarios – the neMIX stirring systems. They can be connected as an accessory to the high-precision syringe pumps of the neMESYS series. The stirring systems enable the mixing of suspensions during the dosing process.

There are two solutions for the creation of homogeneous suspensions: the syringe stirrer and the stirring bottle.

Your Benefits at a Glance

Functionality of the syringe stirrer

How it works

The syringe stirrer consists of a stirring element with a permanent magnet fixed on its tip. This stirring element is inside of a common high quality syringe. A fixture that is mounted on the front part of the syringe contains a rotating permanent magnet. This rotating magnet rotates the stirring element contact-free and the suspension inside the syringe is mixed cautiously.

The stirring element contains an outlet. The coupled syringe pump continuously pumps the suspension through this outlet into the connected microfluidic components.
