===Sample Holders and Scan SOP for microCTs===
====Ex Vivo Sample Holders====
*Ex vivo and inanimate samples are scanned in sample holder tubes. These tubes come in a variety of diameters. It is extremely important that the tube diameter corresponds to, or is smaller than, the field of view (FOV) set in your scanning control file. 

*Biological tissues should be hydrated and wrapped in plastic wrap to prevent drying of the sample. Your sample should then be secured in the sample holder using foam to prevent it from shifting around during scanning, which would lead to poor image quality.

=====Chemical Resistivity of Sample Holders=====
*White tube sample holders are made of PMMA (poly-methyl-methacrylate). 
*Yellow tube samples holders are made of PEI (poly-ether-imide). 
*Use the yellow tubes if you will need to disinfect the sample holder after scanning.

=====Mounting of Sample Holders=====
[[File:Uct35_holder.jpg|thumb|right|100px|µCT35 setup]]
*The spindle (metal bit) of the sample holder has a slot, which must be aligned in the scanner or adapter plate.  
*The sample holder sits vertically in the µCT35 while horizontally in the VivaCT80 and VivaCT40. 
*For the vivaCT40, attach the adapter plate for the tube sample holders to one of the animal bed. The tube sample holders are held horizontally in the vivaCT 40.

====Align whole body device in FOV====

It's important to have your whole sample in the field of view for accurate density measurements.  
* Refer to [[Media:wholebody.pdf |'''Align the device''']] for detailed instructions.
