STOE’s IPDS 2T combines all the achievements of the IPDS II with the possibility to turn the whole goniometer around the Θ axis to an angle of up to 60° yielding a 2Θmax of 137°! This additional axis makes the IPDS 2T a diffractometer of unique versatility. Featuring also the dual beam capability for using two different wavelengths on the same instrument the structure solution of small molecules and proteins as well as electron density determination and powder investigations are no challenge for the IPDS 2T.
On STOE’s Imaging Plate Diffraction Systems IPDS II, IPDS 2T and the STADIVARI with the DECTRIS PILATUS detector the normal pin hole collimator can be exchanged against an X-ray fibre optic. The use of this optic provides a gain in intensity depending on the anode material (eg. factor 2 for Mo Kα, better for Cu Kα), sample dimension (and sample-to-detector distance).
The X-ray fibre optic is an effective and inexpensive alternative to a rotating anode at the STOE Imaging Plate Diffraction System IPDS II, IPDS 2T and the StadiVari with the DECTRIS PILATUS detector.
STOE provides the suitable goniometer head for each task, whether large, standard or small, lockable x,y,z or fully height adjustable, all STOE goniometer heads are of excellent precision, have the standard IUCR mount and are delivered with the necessary equipment.
Low Temperature
O.E.M. attachments like the Oxford Cryosystems coolers can easily be mounted on each STOE single crystal diffractometer. The low cost and low maintenance Desktop Cooler (DTC) can be used as well as the traditional Cryostream or the non-liquid nitrogen Cobra.
Heatstream
As non-ambient methods are becoming increasingly popular, STOE provides a powerful high-temperature attachment for its single crystal diffractometers, the HEATSTREAM.
