Description of the Invention: [Technical Field] The present invention relates to a liquid processing pipette having a multi-channel design. [Prior Art] Modern laboratories, such as clinical and biological laboratories, often require a large number of simultaneous testing operations. Multiwell plates are widely used today to effectively handle such procedures. Conventional multiwell plates can have a configuration of 24 holes, 96 holes six or 384 holes and are configured in a rectangular configuration with a fixed center spacing (channel spacing). For example, a 24-well multiwell plate is configured as a 6x4 array with a channel spacing of 18 mm, a 96-well multi-well plate configured as a 12x8 array with a 9 mm channel spacing, and a 384-well multi-well plate. Configured as a 24" 16 array with a channel spacing of 4.5 mm. Liquid handling operations play an important role in most laboratory procedures. As a primary tool for liquid handling, pipettes can be used to pump and dispense liquid quantitatively. There are a variety of different pipette designs to meet different needs. I and & will use a multi-well plate with a pipette with multiple channels to speed up the process. There are two major types of pipettes on the market today. One of them has a fixed channel spacing and the other has an adjustable channel spacing, which in turn has a more complex mechanism. It is known that a pipette having a fixed channel spacing is an 8-channel type with a channel spacing of 9 mm (refer to Figures 丨 and 2), a 12-channel type with a channel spacing of 9 mm, and a channel spacing of 9 (five) (five). % channel type (refer to Figure 3), or 384 channel type with channel spacing of 4_5 mm. Pipettes with an adjustable channel spacing are 8-channel and 12-channel, with adjustable spacing but typically between 9 mm and 20 mm. 113082.doc 200819198 Pipettes with a fixed channel spacing are generally used with multi-well plates with the same or smaller spacing. For example, a 12-channel pipette with a fixed 9-channel spacing is suitable for 96-well plates and 3-well plates, but not for multi-well plates with a large channel spacing (eg 24 holes) board). Pipettes with adjustable channel spacing between 9 〇1 and 20 mm can be used in 24-well, 96-well, 384-well plates and commonly known as tube-to-plate transfer "liquid handling, ie If a plurality of tubes having a diameter greater than 9 mm are properly configured, a liquid sample in the tubes may be aspirated by a pipette having an adjustable channel spacing and then the liquid sample is dispensed to, for example, a 96-well. In the board. This application effectively accelerates the processing of liquid samples without the need to manually transfer liquid samples from each individual tube to the corresponding well of a 96-well plate. In general, a liquid handler with more pipettes is capable of handling more samples at the same time and is therefore more efficient. As described above, a conventional pipette having a fixed channel pitch is an 8-slot type, a 12-channel type, a 96-channel type, or a 384-channel type. Figures 2 and 2 show schematic views of a conventional liquid handler having an 8-channel liquid handling pipette. It can be seen from the figure that if a conventional 12x8 array perforated plate is to be filled, the liquid processor must perform, pump and dispense, act 12 times, and a liquid processor with a 12-channel liquid processing pipette The 'puffing and dispensing' action must be performed 12 times, both of which are quite time consuming. As mentioned above, the 8-slot and 12-slot arrangements are not suitable for multi-well plates with a large channel spacing ( For example, a 24-well plate.) As described above, a pipette having an adjustable channel spacing has a more complicated mechanism and is therefore more expensive. To overcome the disadvantages of the liquid processor described above, A multi-channel liquid handling pipette is now proposed which is suitable for multi-well plates with different configurations. 113082.doc 200819198 can perform "tube-to-board transfer" compared to the conventional 8-channel and 12-channel processing procedures. ,,, and the way to supply = sample.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 5 is a schematic view of a liquid handling pipette of a channel in accordance with the present invention. The liquid channel pipette 10 has a page portion and a bottom portion. The top portion has just a plurality of inlets (hidden in the figure) and the bottom portion is divided into 2 〇 0. Multiple pipetting heads 2〇1. The 113082.doc 200819198 and other entrances (hidden in the figure) are connected to a syringe (hidden in the figure) or a device with dual functions of quantitative suction and dispensing of liquid (not shown) and connected to the corresponding pipetting head 2CU. When installed in an automated robotic arm (not shown in the figure and by the arm or by hand (snot shown) (four) liquid handling pipette The 1G proximity-perforated plate 3 is referred to as 'tube tip transfer each' corresponding to one of the corresponding holes (or rows) of the perforated plate 300 (see Fig. 7). The perforated plate 300 has a groove between two adjacent holes 3〇1 The track spacing, simultaneous shifting head 2〇1 can be configured as a 6x4 array (refer to Figure 5) and in two adjacent pipetting heads 201 There is a channel spacing of 18 mm. The pipetting head 2 〇 can be more consistently divided by the channel spacing of the pipetting head by the channel spacing of the perforated plate 3〇〇 is a power of two (eg 2 or 4 or similar) Mode configuration. As described in [Summary], a conventional 6x4 (24) array porous plate has a channel pitch of 18 claws (refer to FIG. 6), and a conventional 12x8 (96) array porous plate has A 9 mm channel spacing (see Figure 7), while a conventional 24x16 (384) array of perforated plates has a channel spacing of 4·5 mm (see Figure 8). Therefore, one can be used for 6χ4(24), A typical multi-channel liquid handling pipette 10 with a 6χ4 array of spring 12x8 (96) or 24x16 (384) array multiwell plates can have 18 mm (see Figure 6), 9 mm (see Figure 7) for different purposes or 4·5 mm (refer to Figure 8) channel spacing. Since the ratio of the channel spacing of the pipetting head 201 to the spacing of the upper first channel will always remain constant (one power), the multi-channel liquid processing pipette 10 according to the present invention has flexibility and can be easily modified. Adapted to perforated plates of different configurations, even though the channel spacing of conventional perforated plates is modified for new generation liquid processors.

As described above, multi-channel liquid processing pipette (not shown) It is mounted on an automated arm (not shown) and is driven by the arm. The arm is usually controlled by a computer program. Therefore, the multi-channel liquid handling pipetting officer can be easily controlled and driven to oppose the perforated plate. 3〇〇和—The trial frame 400 moves horizontally or vertically. It can be seen from the figure that the multi-channel liquid processing pipette can be easily controlled and driven to be close to the 6x4 array in the test tube rack 4 And a corresponding tube 401 having a center spacing of 18 mm to suck the liquid in the tubes, and then can be moved to approach and

In addition, because of the 18 111111 channel spacing of the multi-channel liquid handling pipette, the pipette can be lightly > easily accommodated in a suitably configured configuration with a diameter of one of 9_18 mm. Furthermore, the number of rows (6) divided by the number of rows of the perforated plate 300 (12) divided by the multi-channel liquid processing pipette is 2 (power of 2), and the number of rows of the perforated plates (8) is divided by The number of rows of liquid handling pipettes (4) is also 2 (power of 2), so the "tube-to-board transfer"--complete cycle can be completed by 2χ2(4)" pumping and dispensing" .
