Description
Technical field
The utility model belongs to technical field of bioengineering, and the utility model relates to a kind of Digital location device, can make operator exactly to application of sample in the target plate hole of microwell plate.
Background technology
In biological analysis test experience, microwell plate is often used as the container holding detected material and reactant, microwell plate volume size is different, there are 6 orifice plates, 12 orifice plates, 48 orifice plates, 96 orifice plates, 384 orifice plates, 1536 orifice plates, wherein 96,384,1536 orifice plates are particularly suitable for high-throughout analysis detection, such as, in clinical examination conventional enzyme-linked immunosorbent assay (ELISA) and chain polymerization enzymatic amplification experiment (PCR) etc., all need microwell plate as the support vessels of reaction.Reactant in microwell plate, comprises various damping fluid, measuring samples etc., needs to use micropipettor to be added in plate hole.Owing to joining the normally water white liquid of sample in plate hole, be not easy the plate hole of the plate hole of application of sample and not yet application of sample to differentiate.For single sampling, or when injection volume is larger, can whether existing liquid distinguishes by observe from the side in plate hole; But for needing repeatedly the situation of application of sample in same plate hole, particularly application of sample amount is less, when being not enough to be judged by volume difference, cannot distinguish in plate hole whether be added with sample by visual inspection.For this reason, microwell plate can indicate the coordinate (such as B07 represents the plate hole that on microwell plate, the 2nd row the 7th arranges) of each plate hole with letter and number, so that identify during operator's application of sample.This recognition method, needs operating personnel by memory to distinguish in each plate hole whether complete application of sample, not only needs significant attention during operation, and can not be disturbed or interrupt, otherwise probably can not find and even mistake target plate hole.Particularly for the larger testing laboratory of sample analysis amount; the high density plate hole that usual use 96,384 and 1536 orifice plate is such; operator is very frequent to the operation of application of sample in plate hole; namely the volley of rifle fire of 8 passages or 12 passages is used to carry out application of sample; also often sample can be caused to add wrong plate hole because forgetting plate hole coordinate; for the single hole sample operation that injection volume is different, just more easily there is the phenomenon that can not find target hole, thus cause testing result to occur various deviation.
Utility model content
The deficiency that the utility model exists for prior art, proposes a kind of Digital location device and solves the problems referred to above.
The purpose of this utility model is achieved through the following technical solutions:
-kind for the Digital location device of the accurate application of sample of microwell plate, it comprises: for the base of fixing microwell plate and digital scale slide rail, be fixed on the slide rail on base and be connected with slide rail can slide on the track of slide rail and locate digital scale.
Described base is provided with draw-in groove, for fixing microwell plate.
Described base is fixed with slide rail, and described slide rail comprises track, connects digital scale slide block that digital scale is slided in orbit and buckle.The interval of described buckle is determined according to the aperture of microwell plate and spacing, makes digital scale sliding step in orbit be distance between the center of circle of adjacent 2 plate holes.
Described digital scale comprises that support, scale chi are dry, scale pointer and display screen, when digital scale mobile horizontal ordinate and the ordinate that can show present position plate hole in real time on a display screen line by line in orbit.Described digital scale further comprises switch, artificial button, battery and battery cover.
Different with spacing according to the diameter of the plate hole of different densities microwell plate, described scale can set different step-lengths, and make this transverse direction or longitudinal sliding motion on the track of base of scale, sliding step is the distance between the center of circle of often adjacent 2 plate holes.
Preferably, described scale can longitudinal sliding motion, and the pointer now on scale can transverse shifting, transverse shifting step-length be often go adjacent 2 plate holes the center of circle between distance;
Or preferably, described scale can laterally slide, and the pointer now on scale can vertically move, vertically move step-length be often arrange adjacent 2 plate holes the center of circle between distance;
Open semicircle shape hole, the described digital scale pointer upper left corner, described semi-circular hole radius is identical with microwell plate plate hole radius, digital scale can be made to be stirred by application of sample suction nozzle, make scale needle locating in target plate hole, the coordinate of target plate hole is presented on the display screen of digital scale simultaneously.
In described device, the vertical range of described digital scale distance base is adjustable, and the thickness of itself and microwell plate is adapted, so that the pointer on scale and scale can move horizontally.
Preferably, when microwell plate is fixed on after on base, described scale can be adjusted to and microwell plate upper vertical distance 2-5mm.
Compared with prior art, the utility model has the advantage of: after microwell plate being embedded the fixed card slot on base, by adjusting the level height of described scale, make scale can along microwell plate upper surface transverse direction or longitudinal sliding motion, pointer simultaneously on scale can vertical or horizontal movement, orient the coordinate of current plate hole, then the every application of sample of operator once, sample loading gun is stirred pointer and is moved forward a step, above needle locating to next target plate hole, and on digital display screen, demonstrate plate hole coordinate.This device makes operator need not remember plate hole coordinate just can find target plate hole very like a cork, coordinate display on digital screen can also be verified mutually with the design coordinate on operator's shop order, greatly reduce the application of sample error of operator, thus ensure that the accuracy of testing result.
