Accessories philosophy

Below you will find the selection of accessories directly produced by STOE and a selection of third-party systems which are commonly integrated in our diffractometers. However, we are not limited to this selection! One of our defining strengths is to implement components according to our customer’s wishes. Thus, if you have a specific accessory in mind, but cannot find it on this site, please do not hesitate to contact us and our application scientists will be happy to assist you.

Magnetic goniometer head


The goniometer head model designed by STOE is built on a standard IUCr type base and incorporates a magnetic shaft for the pin, which can be securely fastened using a screw. Furthermore, the crystal is centered by screw knobs and a knurled screw for height displacement i.e., completely tool free.

CHARACTERISTICS

  • Magnetic crystal support
  • Tool free centering of crystal
  • Height between 67 and 110 mm
  • Height adjustment without re-alignment of the crystal

AVAILABLE FOR: IPDS II / 2T / STADIVARI

Heatstream

As non-ambient methods are becoming increasingly popular, STOE provides a powerful high-temperature attachment for the IPDS II/2T and STADIVARI single crystal diffractometers, the STOE HEATSTREAM. The crystal, mounted on the goniometer, is positioned in a precisely tempered N2-flow (ΔT < 2 K) coming from below. The thermocouple is fitted in the closest surrounding of the crystal. An exhaustor with a fan is positioned directly above the crystal and removes the hot gas from the diffractometer’s interior. Once the STOE HEATSTREAM’s base is mounted to the instrument, the actual hot gas nozzle can be mounted and removed in a plug and play fashion. With this setup, phase transitions can be screened, high temperature structures of single crystals and powders can be studied and it can even be used for heat treatment and long term annealing of samples.

  • Temperature range from RT to 1000 K (727 °C)
  • Temperature accuracy within +/-1 K
  • Heating medium N2 (open flow)

AVAILABLE FOR: IPDS II / 2T / STADIVARI

xyz stages

For specialized applications, STOE provides two automated sample stages, offering the possibility to control their position through the diffractometer software. Both are based on a standard IUCr mount.

HIGH-LOAD AUTOMATED SAMPLE STAGE

  • Designed for DACs (55 mm diameter)
  • Movement range 9 x 9 x 5 mm
  • Resolution of movements < 1.5 µm
  • Minimal number of cables
  • Suitable for standard DAC weights

AVAILABLE FOR: STADIVARI

LIGHT-LOAD AUTOMATED SAMPLE STAGE

  • Movement range 10 x 10 x 10 mm
  • Resolution < 1.5 µm
  • Movable cable guide, guided below the detector
  • Max. load up to 10 g
  • Protective cover against low temperatures

AVAILABLE FOR: IPDS II / 2T / STADIVARI
