Advantages of DW-XRD-27mini Desktop XRD X-ray Diffractometer

  • More stable

High frequency high voltage X-ray generator guarantees the stability and repeatability of the data.

  • More advanced

Goniometer θs, θd arm adopts servo motor drive and optical encoder control technology. Within the diffraction angle range, the diffraction linearity <0.02. What’s more, DW-27mini XRD adopts the most advanced metal ceramic X-ray tube, it has a long service life (3000 hours).

  • Safer

when XRD is measuring sample, the protective doors are automatically locked to avoid radiation.

  • More convenient

The compact structure can installed onto the platform without a special laboratory environment.

DW27mini 1D Silicon strip based fast detector

1D Silicon strip based fast detector(Model:MYTHEN2 R 1D;Made in Switzerland)

The MYTHEN2 R 1D fits 640 strips into an extremely compact housing and provides surprisingly affordable access to DECTRIS’ HPC technology. The combination of 4 mm strip length and 320 μm sensor thickness allows for fast and accurate measurements with Ti radiation in a laboratory X-ray instrument thanks to MYTHEN2’s excellent signal-to-noise ratio. With 8 mm strip length und 450 µm sensor thickness, the MYTHEN2 is an ideal match for Cu sources, but can also be applied at other X-ray energies.

HPC technology packed in a symmetric design of the MYTHEN2 R 1D, its media-free operation and CE-certificate make it the perfect choice for portable diffractometers, robots for stress measurements, XRD benchtop systems and wavelength dispersive X-ray fluorescence instruments.
