- New Do you know that you can use the Titration-Injection microPump (TIP2k) to perform an instrumental O2 background on the O2k-sV-Module?
- (1) By adjusting the dithionite concentration to 2.5 mM, the instrumental O2 background can be performed with the "BG Feedback" settings. - »O2k-sV-Module«
- (2) By adjusting the TIP2k setup with specific settings for the O2k-sV-Module, the instrumental O2 background can be performed in the O2k-sV-Module. - »O2k-sV-Module«

- New Do you change the slope smoothing to 20 while running experiments with biological sample?
- While running your experiment, especially during uncoupler titrations, it is important to decrease the slope smoothing in order to have a faster visualization of the titrations effect on respiration. - »Slope smoothing«

- New Calibration parameters are transferred to experimental DatLab files
- Save calibration information from selected Marks while DatLab is connected to the O2k during an instrumental calibration run. Air calibration and zero oxygen calibration can be performed and saved in a single DatLab file or in separate DatLab files. - » Oxygen calibration - DatLab«

- Reproducibility committment in high-resolution respirometry: quality control in oxygen calibration
- In the DatLab 7.4 software, new instrumental DL-Protocols guide the user automatically step-by-step, to calibrate the instrument accurately. Reproducibility is monitored and documented when following user-friendly standard operating procedures (SOP). - »Oxygen calibration - DatLab«

- Do you check the O2 flux at the end of the air calibration with the O2k-chamber closed?
- In DatLab 7.4, instrumental DL-Protocols guide you automatically towards closing the O2k-chamber after air calibration, to monitor "O2 slope neg." (negative) as a test of any biological contamination which would increase oxygen consumption in the absence of a biological sample. - »Oxygen calibration - DatLab«
- Do you check the O2 flux at the end of the air calibration with the O2k-chamber closed?
- Your air calibration is not effective until you set mark ‘R1’ and click on Calibrate and copy to clipboard in the O2 calibration window. - »Oxygen calibration - DatLab«

- Do you write the serial number of the polarographic oxygen sensor (POS) in the ‘O2k configuration’ window?
- Including the POS serial number in the ´O2k configuration´ window is important to keep a track record of the sensors used according to the O2k. This will be especially helpful if troubleshooting is needed. »O2k configuration«
- Do you write the serial number of the polarographic oxygen sensor (POS) in the ‘O2k configuration’ window?
- Do you perform O2k-Chamber volume calibration?
- The volume calibration is essential to ensure that the chamber volume is correctly calibrated to its standard volume of 2 mL (or 0.5 mL for the O2k-sV-Module). - »O2k-Chamber MitoPedia«
- Do you perform O2k-Chamber volume calibration?
- Do you use the correct O2 solubility factor (FM) in the ‘O2 calibration’ window in DatLab?
- The O2 solubility factor varies according to the medium used and influences the air calibration. - »Oxygen solubility factor«
- Do you use the correct O2 solubility factor (FM) in the ‘O2 calibration’ window in DatLab?
