How do I eliminate air bubbles in the Mini, Micro and Ultra Micro line of phantoms?
With the Mini and especially with the Micro and Ultra Micro line of phantoms, it can be difficult to always replace all the air in the phantom with liquid. Bubbles large enough to be visible to the unaided eye will likely be large in comparison with structures within the phantom. A reason for this difficulty is the surface tension of water makes it hard to flow easily into and then through small passages. Small (less than 1-2 mm) bubbles tend to stick to surfaces inside the phantom much more so than do larger bubbles. For any Data Spectrum Phantom, NEVER user any kind of alcohol or solvent to fill them. Use of alcohol or solvents of any kind is very likely to damage your methyl methacrylate (MMA) or polymethyl methacrylate (PMMA) phantom. (Please read our Special Notice regarding the use of alcohol and solvents in DSC Phantoms.) Because the gaps between the plates (of the Defrise phantoms) or holes (in the Hotspot or cold rods in other phantoms) phantoms are small, you may encounter so
