A device for rapidly cooling a semiconductor wafer testtransfer machine. A device may be provided, capable of receiving the sample, and performing one or more of a sample preparation, sample assay, and detection step. , by inducing ischemia, of the at least one abnormal blood vessel. Turbo generator is made as two cylinder tubes, divided on isolated sections. These amphiphiles display favorable behavior with membrane proteins and can be used to aid the solubilization, isolation, purification, stabilization, crystallization, andor structural determination of membrane proteins.
