Abstract
The utility model specifically discloses a cell scraping device, strike off the main part including one, the main part of striking off be a hollow siphonozooid, the work end of siphonozooid for the spade. The front portion of siphonozooid be the conical duct, the rear portion is the column pipe, and the pipe diameter of conical duct is less than the column pipe, the inner chamber intercommunication of column pipe, conical duct is as an organic whole, the end of column pipe for inoperative end, with the head cooperation of titrating the rifle when using. The front end of conical duct for work end, its cross section is the spade. The beneficial effects of the utility model are that: strike off main part upper end similar rifle capitiform form, make and titrate the size that the rifle matches, it is to the most researcher in laboratory, convenient easy -to -use.
Description
Technical field
The utility model relates to intracellular matter extractive technique field, is specifically related to a kind of novel for the device striking off material after cracking complete in culture plate.
Background technology
Traditional cell scraper and spatula are used for scraping culture vessel superficial cell, its essentially consist is handle-scraping method and scraping blade, scraping blade width minimum is at present 13mm, although can freely rotate between scraping blade and hanging handle during use, but due to the restriction of scraping blade width, and scrape plate shape and cultivate not mating of plate hole, the edge caused when scraping cells material is remaining.It is only scraping blade exposing cell material during owing to using at every turn, the easy fracture causing handle-scraping method owing to overexerting on the one hand when hand-held handle-scraping method, on the other hand, because the length of handle-scraping method limit, easily cause the false touch of operator's cuff to touch culture plate when operation, add artificially-contaminated probability.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of novel culture plate inner cell removing device.
For achieving the above object, the utility model adopts following technical proposals:
A kind of cell removing device, comprise one and strike off main body, described strikes off the tubular body arranged inside that main body is a hollow, and the working end of described tubular body arranged inside is that centre caves inward, the shape of outer ring outwardly convex.
The front portion of described tubular body arranged inside is tapered tube, and rear portion is cylindrical tube, and the caliber of tapered tube is less than cylindrical tube, and the inner space of cylindrical tube, tapered tube is integrated.
The end of described cylindrical tube is non-operative end, in use with the head fits of titration rifle.
The front end of described tapered tube is working end, and its cross section is spade.
Be provided with screw thread in the end of described cylindrical tube, pass through thread fit with the head of titration rifle.
Described tubular body arranged inside adopts glass to be made into integration.
Described tubular body arranged inside adopts plastics to be made into integration.
Using method: if when needing the cell in scraping culture plate, chooses corresponding supporting titration rifle according to culture plate shape, and extracts and supporting strike off main body, strikes off facing to the cell bottom culturing bottle.
The beneficial effects of the utility model are:
(1) strike off the similar rifle head shapes in main body upper end, make the size of mating with titration rifle, for laboratory major part researchist, facilitate easy-to-use; (2) to strike off face size less in lower end, and the shape striking off the spade design of main body bottom can well adapt to the geometrical shape of circular culture hole, and complete scraping rate is high; (3) each use only changes removing device main body, well can also save consumptive material in addition.
Accompanying drawing explanation
The structure of Fig. 1 culture plate;
Fig. 2 one-piece construction in use of the present utility model;
The structure iron of Fig. 3 removing device main body of the present utility model;
Wherein 1 titration rifle, 2. tubular body arranged inside, 3 culture plates.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Figure 1-3, novel culture plate inner cell removing device, comprise and strike off main body, described main body of striking off is a tubular body arranged inside 2, and the working end of tubular body arranged inside 2 is that centre caves inward, the shape of outer ring outwardly convex, its cross section is spade, for striking off cell, its cross-sectional shape is cambered design, and the working end of tubular body arranged inside 2 is the face of striking off.Strike off the shape that main body has arc-shaped bend, can match with circular culture hole; The rear end of tubular body arranged inside 2 and laboratory are commonly used titration rifle 1 and can be supported the use; Be divided into large, medium and small model.
The front portion of tubular body arranged inside 2 is tapered tube, and rear portion is cylindrical tube, and the caliber of tapered tube is less than cylindrical tube, and the inner space of cylindrical tube, tapered tube is integrated; The two ends of tubular body arranged inside are provided with opening, and one end open is positioned at the front end of tapered tube, and the other end opening is positioned at the end of cylindrical tube, and the front-end cross-sectional view of described tapered tube is spade.
If when needing the cell in scraping culture plate, choose corresponding supporting titration rifle according to culture plate shape, and extract and supporting strike off main body, strike off facing to the cell bottom culturing bottle; The end of cylindrical tube is connected with titration rifle 1 in use.
The internal diameter of tapered tube is 2-4mm; The external diameter of cylindrical tube is 8-12mm.
Tubular body arranged inside 2 is made into integration with glass or is made into integration with plastics.
Claims (7)
