I am using SFR / SFR vario. What is the difference between SFS v3 and SFS v4?

The shake flask reader SFR vario requires special positioning of the alignment knobs at the sensor flask bottom. Therefore, the SFS v4 was introduced. SFS v4 can be used with both, SFR vario and SFR Shake Flask Reader (9-channel device), while the SFS v3 can only be used with the 9-channel device SFR. A short introduction on how to position the clamps on the SFR so it can be used with SFS v4 is available for download.
