Switching steering off during OD measurement

[konst_ac]

Hello!

We would like to stop steering every time the OD is measured to get a more precise result. From what we understood the OD measurements occur atomaticaly on the server without any instructions from the client, so a simple emit of a new massage will not be sufficient.

Can you, please, recomend a strategy for us or point to the bit of code on the server, that we could change in order to turn the steering off, and on again?

Hopefully this helps:

At lower culture volumes optical density readings are affected by stirring

I think the vortex from the stir is the main thing causing the issue here. If you need lower volumes in the standard eVOLVER culture vial with OD measurements, do not go below 10 mL and be sure to turn the STIR off for ~20s before taking an OD measurement to allow enough time for the SAMD21s to collect clean data. Thanks for the write up! It’s great to have these details documented.
