Description
Technical field
The utility model belongs to labware technical field, is related to a kind of adjustable drop piece for preparing chromosome specimen piece
Device.
Background technology
The number and structure of eukaryotic chromosome are one of important Heredity index.It is that cell is lost to prepare chromosome specimen
Pass most basic technology of learning, including cell collection, Hypotonic treatment, fixation, drop piece and the several crucial steps of dyeing.Wherein, drip
In this link of piece, height when dripping piece is critically important, and highly too low cell will not rupture；Too high then chromosome excessively disperses even
Lose, the accurate quantity of chromosome can not be identified.Moreover, preparing the chromosome specimen of different type cell, needed when dripping piece
Height have very big difference, some needs dropper away from slide 20-30cm；Some requirement droppers are away from slide 10-15cm；Some is apart from glass
It is sufficient that piece 1-3cm.
In order to meet above-mentioned adjustable for height needs, a kind of existing disclosed chromosome drop piece fixing device, including base
With the graduated pole of band for being vertically set on base side, the dropper moved up and down along pole presss from both sides to be extended to base center,
Dropper presss from both sides is provided with set screw between pole, it is achieved thereby that the purpose of adjustment dropper high and low position；But still nothing be present
Method accurately adjusts the problem of height, because dropper has length in itself, the dropper after installing in the horizontal direction is carved apart from band again
The pole certain distance of degree, dropper end can not be measured by pole at all to the distance of slide；Along with dropper folder is also deposited
In certain width and scale local on pole has been blocked, and the dropper after each installation in vertical direction, relative to drop
The length of pipe clamp is difficult to control unanimously, therefore the altitude reading of dropper does not have unified standard and judgment, causes final height
Judge that inaccurate even error is very big.
Further, since the device is additionally provided with drop piece location-plate in the middle part of base, set between base and drop piece location-plate
Right position adjusting part is equipped with, two sides up and down of drop piece location-plate are provided with angle of inclination regulating part, drip piece location-plate
On be provided with drop piece fixed mount, for adjust drop piece location-plate coordinate position and angle of inclination.Structure is relative complex, operation
It is cumbersome, and cost of manufacture is high.
The content of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of adjustable chromosome specimen piece for preparing
Sheet devices are dripped, drop piece height can be accurately held, raising prepares the conventional efficient of chromosome specimen piece, and saves experiment mark
This.
The utility model solves the technical scheme that its technical problem uses：Including base and it is fixed on carrying on base
The vertical rod of graduation mark, a dropper fixing device is flexibly connected in vertical rod, the dropper fixing device includes and dropper profile chi
Placed cavity, waling stripe and the adjustable knob of very little matching, placed cavity and adjustable knob are fixedly connected on the both ends of waling stripe, drop
Pipe fixing device is arranged in vertical rod by adjustable knob, is additionally provided with vertical rod, positioned at the same side-lower of dropper fixing device
One slide platforms, slide platforms and dropper fixing device align arrangement, the scale in vertical rod by with slide platforms
Junction is started at, and the lower end of placed cavity stretches to the indicator of vertical rod with level, and the bottom for the dropper being placed in placed cavity is firm
The plane being located at well where indicator.
Compared with prior art, a kind of adjustable drop sheet devices for preparing chromosome specimen piece of the present utility model, not only have
There is vertical rod with a scale, and the scale of vertical rod is started at position and located where slide, and it is calculated between dropper and slide
The terminal of height, it is indicator possessed by placed cavity and the placed cavity lower end by being matched with dropper appearance and size, limits
In the bottom of dropper, the distance that such vertical rod high scale line finally measures is exactly height of the dropper bottom to slide,
This is definite drop piece height, it is seen then that can not only be adjusted by the utility model dropper device and clear and definite all kinds cell
Need to drip the height of piece, particularly, the height of measurement be it is accurate, and the design of indicator also make the reading of height intuitively,
Simplicity, therefore be truly realized and held drop piece height exactly, improve the conventional efficient for preparing chromosome specimen piece, while
Slide and dropper align aspect, as long as manually adjusting position of the slide in slide platforms, you can meet real
Test and require that, it is simple in construction, it is easy to operate, save experimental specimen.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the utility model one embodiment.
In figure, 1, waling stripe, 2, placed cavity, 3, indicator, 4, slide platforms, 5, slide groove, 6, base, 7, vertical
Bar, 8, adjustable knob.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched
The embodiment stated is part of the embodiment of the present utility model, rather than whole embodiments.Based on the reality in the utility model
Example is applied, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is all belonged to
In the scope of protection of the utility model.
Fig. 1 shows the structural representation of one preferred embodiment of the utility model, a kind of adjustable preparation in figure
The drop sheet devices of chromosome specimen piece, including base 6 and the vertical rod 7 with graduation mark being fixed on base 6, the setting of scale
Can be by centimetre in units of, be easy to clear and definite all kinds cell to need to drip the height of piece, a dropper be flexibly connected in vertical rod 7
Fixing device, the dropper fixing device include placed cavity 2, waling stripe 1 and the adjustable knob matched with dropper appearance and size
8, placed cavity 2 and adjustable knob 8 are fixedly connected on the both ends of waling stripe 1, and dropper fixing device is arranged on by adjustable knob 8
In vertical rod 7, its position can be adjusted by adjustable knob about 8, be easy to find suitable drop piece height, in vertical rod 7, be located at
The same side-lower of dropper fixing device is additionally provided with a slide platforms 4, and slide platforms 4 align cloth with dropper fixing device
Put, by being started at the junction of slide platforms 4, there is the scale in vertical rod 7 level to stretch to vertical rod 7 for the lower end of placed cavity 2
Indicator 3, the bottom for the dropper being placed in placed cavity 2 are located just at the plane where indicator 3.
The effect of base 6 described in the present embodiment, primarily to being easy to the stable placement of device, so the tool of base 6
Body structure is not construed as limiting, and can be designed to various conventional shapes, and selects existing various materials, but prioritizing selection weight is big
The type of point, such as metab etc., so in the operating process of experiment, whole device is more firm, so as to not influence reality
