Multiple sample support assembly and apparatus for facilitating radioimmunoassays and the like

摘要: An improved multiple sample handling system, including a fully machine-compatible support assembly, vortexing apparatus, and radioactivity sensing is disclosed which enables performance of complete radioimmunoassay or competitive binding procedure on the samples in generally without need to remove handle individual samples, greatly increases processing speed error avoidance. The assembly includes an apertured tray retainers cooperating therewith supporting tubes by radially inwardly acting gripping portions. fit loosely within apertures, but displacement control means are defined permitting together with smoothly move angularly relative small predetermined solid angle. self-supporting upon for storage optionally during operation. For mixing reagents, simultaneously vortexed apparatus supported while surface applying orbital forces contacts lower tube Mass centrifuging decanting readily performed only. one phase each sensed counting device cooperates chamber head accesses from below enable plurality be counted simultaneously, removing their assembly.
