AT-XRD-XX is an air-tight sample holder of a zero diffraction plate for powder XRD. Zero diffraction plate with the option of OD 24.6, and 32 mm, which is put inside of the stainless steel holder. The top of the sample holder is covered by Kapton film and tightened by PTFE O-ring. The air-sensitive powder will be put in the cavity of the zero diffraction plate inside the inert gas glovebox.( Since August 22, an Air-tight sample holder will include one zero diffraction plate )Specifications Structure Please click the picture to see the details 40 mm OD x 9 mm thickness Zero Diffraction Plate One Si single crystal zero diffraction plate with a cavity is inside the sample holder The zero diffraction plate is made of single-crystal Silicon which is cut at the special angle Two types of zero diffraction plates are optional from the product option bar Diameter: 24.6, or 30.0 mm with 10 mm dia. x 0.2 mm depth cavity Please choose size at the options bar, and click the pics below to order a zero diffraction plate 24.6mm 30.0mm XRD Plate package. 10 pieces of Kapton film 2 PTFE O-rings One zero-diffraction plate Reference Video
