++suspension of microcrystals, **at least** 200 µL with 20% crystal density (more is always better), size range: 2-30 µm, **tip:** bring some mother liquor for washing, filtering, diluting etc.
++
++Preparation:
++
++* filter through 30 µm cell filter (green) or 50 µm (yellow)   into Eppendorf or Falcon (original!) tube

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

++* Change the velocity by typing anything from **0.3-3.0 mm/s**
++* Common velocity is 1.0-1.5 mm/s

++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.
++The absolute position is **not calibrated** and therefore changes after each restart of kamzik.

++\\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.

++* Cut the tape with some cm overlap to glue to the new roll. **Do not discard empty roll!**
++* Get a new tape roll (bottom left on the cart). **Polypropylen 15 µm**
++* Cut the first cm of the new tape roll, directly behind the black sticky part.
++* Place new roll on roll holder and use sticky tape to attach the end of the old tape to the beginning of the new roll.
++* Open magnetic tape stabilizer on the **left side**. (% style="color: rgb(255,0,0);" %)//!!!BEAMSTOP!!!//
++* Start the tape (3mm/s). Once the connetion side has arrived at the collector roll, stop the tape (0mm/s).
++* Again, cut the tape directly behind the connection side. Replace the the old roll with the **empty **one. Old roll can be discarded.
++* Attach new tape to the empty roll by using some sticky tape.
++* Close tape stabilizer.
++* Reset tape counter in kamzik by clicking "<Call>" in "Main-Tape".
