Inquiry (采购产品): Hollow plastic spheres Hi, we require small hollow spheres for our research work. They are to be injected with a small amount of radioactivity. The actual substance being injected is fluoro-deoxyglucose which results in gamma radiation. The spheres will contain the radioactivity for a couple of hours. We need spheres with diameter of approximately 10-20mm (roughly 1/2 " - 1"). We would most likely drill a small hole in the sphere in order to inject the fluid. At this stage we require roughly 20 spheres. Is it possible for us to arrange for this small order and shipment to Sydney? Of course we are happy to negotiate an appropriate fee. Any help would be greatly appreciated, Andre Kyme **** Hidden Message ***** Andre Kyme 2006 AUS Company: Sydney University E-mail: a.kyme@physics.usyd.edu.au **** Hidden Message ***** a.kyme@physics.usyd.edu.au
