31 -After filtration, screw the ElveFlow connector to your Eppendorf or Falcon tube. Make sure that the yellow-ish line goes to the bottom of your tube. You can adjust the length by unscrewing the blue fitting on top and pushing/pulling the yellow-ish line. **Don't forget to tigthen the blue fitting afterwards!**

71 -The nozzle position can be adjusted in xyz by clicking on the arrows up and down. (Double arrow = 10 steps). Step size can be varied, 1mm steps are rather big and should be used carefully.

76 -\\Adjust the nozzle position by eye until it nearly touches the tape and roughly meets the X-ray interaction point. Then, move to the control hutch to use the on-axis microscope for fine adjustment. Move the nozzle tip to the beam position (red X) and write down the absolut nozzle position. From there move the nozzle in +x to your desired distance.Different distances combined with the tape speed result in several delay times for time-resolved experiments.
