18 +Preparation:
19 +
20 +* filter through 30 µm cell filter (green) or 50 µm (yellow) into Eppendorf or Falcon (original!) tube

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!**
32 +
33 +Be aware to which channel and nozzle line your sample is connected.
34 +
35 + Red → Channel 1, crystal line (nozzle capillary without marks/with red marks)
36 +
37 + Green → Channel 2, substrate line (nozzle capillary is marked in black)

52 +The TapeDrive is controlled through kamzik. To open kamzik, start the server. A terminal will open and shortly after a small window.
53 +Now start the client. Same thing, a terminal will open, shortly after a small window.
54 +

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.
