ABSTRACT:
There is disclosed apparatus for automatically extracting compounds of clinical significance from a plurality of biological samples simultaneously by elution using a multi-channel system with common sources of wash reagents and eluent and common pre-programmed controls for all channels including means to purge wash and dry the channels between stages and means to inject essentially inert gas plugs as the interfaces between subsequent liquid phases. The extracted compounds can be mixed with reagents, mechanically agitated and examined qualitatively and/or quantitatively as by spectrophotometry to yield output readings for all channels. The flow patterns within the channels are determined by liquid-apportioning means and fluid distribution and metering, including both liquid and gaseous is accomplished by valves which respond to single control inputs to effect flow in all channels simultaneously.
