» The dimensions of the magnetic stirring bars are nominal dimensions which can have a tolerance of +/- 5% in length and +/- 10% in diameter.
Results of stirring – tested for you
In order to help you choose the suitable magnetic stirring bar for your application, we have made tests with these data under real conditions. You will find graphs for each magnetic stirring bar on the next pages.
We “meliorate” your specific magnetic stirring bars
» These stirring bars can for example be built in devices or can be used
for special applications.
» The diameter of the magnetic stirring bars can be machined with a tolerance of up to +/- 0,02 mm.
» The magnetic stirring bars are ground to obtain a seamless amplitude.
» The ends are polished to receive a round or any other shape.
» The surface is becoming extremely smooth and even, so that contaminations cannot adhere.
» Reproducibility both in diameter and surface are granted.
