CONTINUOUS feeding of MICRO-
CRYSTALS into the X-ray beam

TAPE DRIVE TD-1

Flexibility, stability and user-friendliness for experiments

Time-resolved serial crystallography experiments require the continuous delivery of microcrystals to the X-ray beam.
Our tape drive TD-1 transports a suspension of microcrystals, applied as a thin line onto an ultrathin Mylar foil, into the X-ray beam.
The TD-1 provides great experiment flexibility and is ideally suited for chemical mixing experiments and light excitation
of the sample using our on-axing sample viewing system.

Low scattering background

  • Use of ultrathin 6 µm mylar foil minimizes parasitic X-ray scattering from the tape
  • Blotting of the suspension liquid through micropores in the tape reduces liquid scattering
  • Optional local helium path for the direct X-ray beam suppresses air scattering

User friendliness

  • Easy exchange of mylar and blotting tape by using magnetic tape roller mounts
  • High reliability due to streamlined design and well tested component
  • Intuitive graphical user interface for easy operation (in combination with the optional controller)

Experimental flexibility

  • “Breadboard-like” design allows custom configuration of tape rollers, tape guide pins and tape tensioner
  • Compact dimensions allow easy integration to existing experimental environments
  • Use of industry standard 2-Phase stepper motors allows easy integration into existing control systems
  • Optional controller SC-1 with touchscreen integrates seamlessly into existing control systems via ethernet

Integration into the suna ecosystem

  • Ideally used in combination with our motorized syringe pump SP-1 (link) and anti-settling device AS-1 and our controller SC-1
  • Compatible with our on-axis sample viewing microscopes OM-1 and OM-2 for visualization and laser excitation of the sample
  • Easy integration with the roadrunner goniometer
