  • a number of automated systems have been provided for performing chemical reactions and analyzing the results.
  • Such systems characteristically include a series of receptacle holders or carriers, for test tubes and the like. which are moved by a conveyor past a series of different treatment stations. Individual of these treatment stations may. for example, provide filling of the test tubes with sample liquid and reagent, heating or other treatment of the sample liquid and reagent within the test tubes, withdrawal of the sample liquid and reagent from the test tubes and washing of the test tubes, each during a predetermined part of the programmed operating cycle of the conveyor.
  • the time necessary for conveying a selected receptacle from the active area of a first treatment station to the active area of a second treatment station is varied. In this way, it is possible to vary the reaction time for the chemical reaction which occurs when a particular reagent is added to the same liquid.
  • an arrangement wherein provision is made for rotating the receptacle holder at a selected point along the path of travel thereof in accordance with a predetermined analyzing program.
  • the angle of rotation is made equal to the angle formed between a radial line from the center of the holder and a first receptacle and a radial line from the center of the holder and a further receptacle.
  • the arrangement also includes devices for supplying liquid to at least one receptacle of the holder and for removing the liquid after the reaction in question is complete. as well as some form of analyzer for the recovered liquid.
  • the invention includes a pair of rails or bars along which the holders are conveyed and which normally prevent rotation of the holders. Recesses in the bars at a predetermined location therealong permit rotation of the holders at that location through the cooperative action ofa toothed gear track on one of the bars and corresponding gearing on the holder.
  • FIG. I is a highly schematic plan view of an automatic analyzing arrangement according to the invention.
  • FIG. 2 is a perspective view of one embodiment of a portion of the arrangement shown in FIG. I, with certain parts omitted for purposes of clarity;
  • FIG. 3 is a plan view of the embodiment of FIG. 2 showing two holders in different rotational positions:
  • FIG. 4 is a vertical section of the holder of FIG. 2'.
  • FIG. 5 is a highly schematic representation of another embodiment of the holder of the invention.
  • FIG. 1 a schematic representation is presented of an automatic analyzing arrangement incorporating the invention.

It will be understood that the number of receptacles 12 as well as their arrangement in the holders 10 is merely exemplary and. as will be apparent from the description hereinbelow, the number of receptacles 12 can be any number greater than one, within practical limits.
  • Holders I0 move along a path which is indicated by broken lines 14, the holders I0 being conveyed on path 14 by suitable means (not shown in FIG. 1 so that each holder 10 returns to a predetermined reference point or station along the path after a selected time interval.
  • sample liquid and reagent may be supplied to one or more of the receptacles I2 therein by means of a dispensing device indicated at 16.
  • the dispensing device 16 may comprise a series of pipettes connected to pumps (not shown) or can take any of a number of other conventional forms characteristically used in connection with automatic analyzing machines.
  • the path 14 is provided, at a further point or station II, with an arrangement (not shown) for turning or rotating a holder I0 about the vertical axis of the holder, this rotation being indicated in FIG. 1 by arrow 18.
  • rotation of a holder I0 is provided at station II.
  • the length of path 14 relative to the speed at which holders 10 are conveyed is such that a holder 10 will return to starting position after 6 minutes, the times during which a holder 10, starting at station I, will pass each of the other stations being indicated by the designations l min.. 2 min. and so forth, as illustrated.
  • the mixture can be supplied to the receptacle at a station I, the holder 10 conveyed along path 14 so that station II is passed four times. and, when the holder I0 again reaches station III. the liquid withdrawn from the receptacle.
  • station I" may include a suitable withdrawal device, indicated at 20, for removing the liquid from a receptacle I2, and an analyzer. which is indicated at 20 and which can be a photometer or another conventional analyzing device, for analyzing the result of the reaction.

  • sample liquid is supplied simultaneously to two receptacles of a holder I0. e.g.. to holders a and b. Further. the holder I0 is rotated 180 at station II. If the holder I0 is conveyed along path 14 so that station II is passed twice. holder 10 reaches station IV after Ill minutes whereupon the reaction product can then be withdrawn for analysis as set forth above. Under these conditions. the arrangement functions as a two channel analyzing apparatus. each channel having a 10 minute reaction time.
  • sample liquid and reagent is supplied to each of the receptacles a to d at station I, and the result of the reaction is ob tained when the hold reaches station V after 5 minutes.
  • the arrangement thus operates as a four channel analyzing apparatus.
  • operation can be provided with two channels having a 5 minute reaction time and one channel having a minute reaction time, if the holder 10 is rotated at suitable positions along path 14 under the control of a suitable operating program. If the number of holders 10 in the path 14 is uneven and if each holder 10 is moved a distance equal to the distance between every second holder.
  • further combinations can be provided.
  • the analyzing arrangement can be made up of separate units so that a variation in the reaction time can be obtained by adding or removing one or more of the units.
  • station V can be provided with a cleaning set-up (not shown) for cleaning the receptacles l2 and drying them with air.
  • the cleaning setup would, of course. be controlled so that cleaning is limited to those receptacles for which analysis has been completed. It is possible to omit cleaning ofthe receptacles where the receptacles are of a disposable type.
  • FIG. I Although the operation of the arrangement of FIG. I has been explained relative to a single holder 10, it is obvious that a relatively large number of such holders can be utilized.
  • the chieflimitation on this number. for a given path 14. is the amount of space required to permit rotation ofa holder. which is determined by the distance between adjacent holders as well as the particular size and design of the individual holders. Further. with the proviso that rotation of the holders not take place at or near a station where liquid is supplied because of possible interference with the supply pipettes, rotation of a holder can be provided at any position along path 14 and, further. where desired. a holder can be rotated at several different stations.
  • FIGS. 2 to 4 there is illustrated a preferred embodiment of a holder, a conveyor for the holder and a station for providing rotation of the holder.
  • the conveyor forming path 14 of FIG. 1 includes first and second spaced slide bars 24 and 26 each of L-shaped cross section.

  • twelve receptacles may be received in a single holder 40. If the holder 40 is rotated 90 at station ll, sample liquid together with reagent will be supplied at position I to those three receptacles which lie along line 42. When the holder next reaches position I and hence is rotated 90", sample liquid and reagent may be supplied to those receptacles which lie along line 44. Further, by a suitable arrangement of the fluid supply device and the device for analyzing the re action, a number ofdifferent combinations of analyzing channels and reaction times can be achieved with the holder of FIG. 5.
  • sample liquid and reagent can be caused to pass along the path 14 twelve times before the reaction result is analyzed while. in accordance with another extreme.
  • sample liquid and reagent is supplied simultaneously to all twelve receptacles at a station corresponding to station I and the reaction results are simultaneously read off at a station corresponding to station V. i.e., when the holder 40 has been conveyed only once around the travel path thereof.
  • the dashed line 46 in FIG. 5 indicates how a selected group of three receptacles can be combined.
  • Sample liquid and reagent are supplied simultaneously to the receptacles in this group and liquid is withdrawn simultaneously from the receptacles to provide analysis.
  • An arrangement for conveying receptacle holders along a predetermined path to different treatment stations in an automatic analyzing apparatus comprising means for conveying at least one holder along the path, means located at at least one location along the path for selectively rotating the holder relative to the path, the angle of rotation being equal to the angle formed between a radial line between the center of rotation of the holder and one receptacle of the holder and a radial line between said center of rotation of the holder and another receptacle of the holder, means for supplying a fluid to at least one receptacle, means for recovering the contents of the receptacle to which the fluid is added and means for analyzing the recovered contents.
  • said liquid supply means comprises a device for supplying liquid to a predetermined number of receptacles of a holder and said analyzing means comprises means for simultaneously analyzing the contents of a like number of receptacles of the holder.
  • each holder includes a multiple m of n receptacles and said angle of rotation is equal to l/m th of a complete revolution of the holder.
