Description

concerning
Sampling device

The invention relates to a sampling device, i.e. a device for distributing a fluid flow to a plurality of receptacles, particularly for distributing of a liquid stream with time-changing ^ composition :. For example, such Sampling device used together with a device for chromatographic analysis or separation in which the liquid from this device is to be distributed into a large number of vessels in order to be analyzed to become.

In a known construction of a sampling device: are the receptacles, usually Reasr-enzblaschen, arranged in several concentric circles on a circular, rotating table. The table will gradually rotated, and the filling nozzle for the liquid is in the radial direction of a circle of reagent vials

moved to the next. A main objective of the invention is in creating a sample collector that isb more compact than the known sampling devices and therefore takes up less space and makes it possible to use a fixed filling nozzle; the relative movement between the filling nozzle and the test tubes depends on the reagent bottles.

One embodiment according to the invention includes a rectangular one Base part; compartments provided on this base for receiving a plurality of holders; rectangular, elongated Holders attached to this base in all but one compartments and arranged in two rows, wherein each holder can accommodate a plurality of receptacles for the samples; Means to each at the end move the holder in each row gradually into the other row; and means to all holders of each row to move in the longitudinal direction of the row. This embodiment is set up for a single filling point. In another embodiment according to the invention the holders are on the base part in all but two compartments intended. This embodiment is suitable for two filling points, as follows with the aid of the schematic tables Drawing is explained in more detail.

The device shown consists of a rectangular one Base part 1, on. the elongated, box-like holder 2 are provided, which; receive the test tube racks 3, each containing ten reagent vials. The keepers

are arranged in two rows, each row at most can accommodate sixteen holders. As such, each row comprises only fifteen holders. This allows the one at the end Holders in each row were moved lengthways to to clear the compartment in this row. In the one shown Position the holders 4 and 5 at the end of the row are moved from one row to the other in the direction of the arrows others pushed.

When the reagent vials are filled, they are in the at 6 and? indicated position. Above are the filling nozzles for a liquid coming from a chromatographic apparatus, for example. The one shown The device is therefore off for the real time two pillars set up.

Parts h and 9, shown in simplified form, push the holders simultaneously and in stages from one row to the other, each stage corresponding to the distance between the axes of two adjacent test tubes and have been re-filled in position ö or 7, parts 8 and 9 move twice the distance and thereby push the last Reaerenzchrchen from position or 7 directly into position 14- or% Ah, it is not It is necessary to stop the last reaffirming tabs in positions 12 and 13. The Hr-Itex can be moved at predetermined time intervals

a -container -with., which is additionally connected to the filling nozzle; Liquid has been filled, with all reagent tubes _: so filled with the bleached liquid residue. The technical principles and the automatic devices for filling the reagent tubes are known in the chromatographic field; they are not explained further here.

All holders in each row are moved step by step from parts ■ 10 and 11, as shown in a simplified manner is. At each step, the holders are moved a distance equal to the width of one holder.

The actuators for parts 8, 9, 10 and 11 are synchronized in a known manner so that the
Parts 10 and 11 become effective when the parts 8 and 9, the holder located at the end row have ieder move 4- or 5 ^of one row to another he ^r ^ n et.

In order to make the apparatus shown as space-snaring as possible, it is desirable that the holder and the receptacle bottle racks are as narrow as possible. So that such elongated, narrow rims can stand after they have been removed from the sampling device, they consist of two sections. which by means of a joint with each other
are connected. Each section contains five reagent tubes. Set up on the stand on a table, turning the zvei parts ^ o. that they are at an angle to each other.

In a modified embodiment, the illustrated Include device instead of JO 31 holder; the filling takes place in position 7 and all test tubes in the clear B are filled as described. Then the holder 5 is in the right row, the left row one step behind below, the top holder in the right row quickly to the left and slide the right row up one step postponed. Consequently, such an apparatus is only for a filling point is provided.
