Hello,
What version of the reactor do you have? It should say on the outside of it V1.1, V1.2, etc…
Some of the older versions sometimes had stalls with stirring, which we fixed in subsequent generations.
Regardless, the best approach to avoid this would be to use a smaller stir bar, or one that is “easier” to turn (e.g. has few sharp edges), and run at a higher speed.
Hello, I am not sure exactly which reactors do/don’t have it rectified since they are put together at the manufacturer so I don’t see the interior. Could you tell me the height of the reactor – measuring just the PCB/body of it (i.e. ignore the screws/feet on bottom) so I can investigate?
Regardless, the best option would be to follow the advice above, and attempt different stir bars.
Alas I think that means it doesn’t have the fix. You could take the sides off and look if you desire – the change we are looking for is whether there is a 3d printed part approx 1cm high holding the magnets in the bottom above the fan.
Have you tried different stir bar designs as I mentioned above? You can get variety packs of different stir bars (e.g. of eBay) and then pick one that gets along with your reactor.
