1,187,202. Automatic analysis apparatus; moving band filter. WRIGHT SCIENTIFIC Ltd. and A. POLLARD. 14 March, 1967 [14 March, 1966], No. 11082/66. Headings B1D and B1X. Apparatus for filtering precipitates for examination in automatic analysis procedures, for example the radio immune assay of insulin, comprises an extended strip 4 of filter medium, reinforcement applicator 20, 19 for applying for example rubber solution to the edges of strip 4, filtration unit 7 including a liquid permeable filter support and means included in 33-36 for discharging a liquidsolid mixture for filtration on to the strip, drying unit 8, laminating unit 9 for continuously securing a protective lamina 12 over at least one surface of the strip, and means for advancing strip 4 successively through applicator 20, 19, filtration unit 7, drying unit 8 and laminating unit 9. The strip may then pass through detector unit 55, for example a geiger or scintillation counter, and is then wound by reeling unit 17. Strip 4 may be of felted glass fibre and may be supported on a perforated strip of polytetrafluoroethylene 26 over perforated steel plate (25) (Fig. 3 not shown). In the analysis apparatus of Fig. 5 (not shown) samples of insulin-containing material from turntable (70) are mixed with antibody suspension from (73) and with labelled insulin from (74). An air-segmented stream of treated samples passes through reaction coil (84) and is delivered through nozzle (34) on to strip 4 for filtration. |
