Description

A kind of Dumpage type improvement Tissue Culture Flask

Technical field

The utility model relates to a kind of cell cultivation equipments, and in particular to a kind of Dumpage type improvement Tissue Culture Flask.

Background technique

Cell culture is a kind of common biomedical technology, important function has been played in life studies, in cell culture In operating process, it is known that cell bottle, be unfavorable for toppling over for cell culture liquid, mainly use pipettor equipment, it is cumbersome and The consumption for increasing man power and material, when needing to topple over operation, Nostoc commune Vanch bottle can residual liquid in bottle and bottleneck, neither Conducive to the movement of culture liquid and the digestion of attached cell, and increase the chance of pollution.

Utility model content

In view of the above-mentioned problems, the utility model provides a kind of Dumpage type improvement Tissue Culture Flask, both with cell culture Function, and can easily topple over transfer and removal liquid in the transfer process of culture liquid and cell, reduce residual and dirt Dye.

A kind of Dumpage type improvement Tissue Culture Flask, including body, bottleneck and the transition part for connecting body and bottleneck, the bottle Body includes bottom wall, roof and side wall, on the inside of medial surface that the transition part is connected with bottom wall and the bottleneck being connected with the medial surface Face is located along the same line.

The utility model Dumpage type improvement Tissue Culture Flask improves bottleneck on the basis of ordinary cells culture bottle Design allows the liquid in bottle in toppling process, and speed away culture bottle, and residual quantity is less, this process is superior to pipettor and sets Standby operation, and provide equipment for cell culture automation and support.

Preferably, the body is rectangle body, including a bottom wall, a roof and three side walls, the transition part It is connected with bottom wall therein, roof and two pairs of two side walls.

It is further preferred that graduation mark is arranged on the body.

For first Curve guide impeller of bottleneck, transition part, to bottleneck, is not transferred, is had along linear extension connection bottleneck Conducive to liquid removal.

Preferably, the joining place of the transition part and body bottom wall is in 160~165 ° of angles.

As another Curve guide impeller of bottleneck, the port of the bottleneck is bottleneck, and bottle mouth position is set as arc-shaped and outside The horn mouth turned over.

Bottleneck is from being in that arc row is outwardly formed toy trumpet mouth at top edge 1mm, and bore is no more than bottleneck thread size, this will be advantageous It speeds away bottleneck in most of liquid, residual liquid generally will not be to outside bottle, and when bottle is stood, residual liquid can be most of It returns in bottle, reduces opportunities for contamination.

Upper end constriction and bottleneck of the Tissue Culture Flask of the utility model on original Tissue Culture Flask are improved, It completes liquid in bottle and smoothly topples over function.

Preferably, the bottleneck is cylinder.

It is further preferred that the bottleneck is equipped with external screw thread.

It is further preferred that a length of 1.5~2.5cm of bottleneck, bottleneck diameter is 1~2cm, straight at horn mouth maximum gauge Diameter is greater than 0.15~0.25cm of bottleneck diameter and is less than external screw thread maximum gauge.

Still more preferably, neck length 4cm, bottleneck diameter 1.5cm, collar extension end loudspeaker maximum gauge 1.7cm.The long * wide * of bottle body Height=5cm*4cm*2cm, wherein length and width can be with random fluctuation.

It is further preferred that further including the bottle cap with bottleneck thread cooperation.

The utility model will shorten the cell culture operations time, not need the use of pipettor equipment, indirectly reduce portion Divide the consumption such as pipette tips, suction pipe, corresponding disinfection etc. decreases cell exposure open environment time, liquid remaining influence Attached cell digestion and bottleneck liquid residual contact outside contamination hidden danger, while being conducive to large-scale mechanical automation cell Operation is toppled in culture.

The culture bottle of the utility model simplifies the part operation process of cell culture, reduces drain on manpower and material resources, And reduce pollution, promote the progress of cell culture technology.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the sectional view of the utility model.

Fig. 3 is the enlarged drawing of part A in Fig. 2.

Appended drawing reference as shown in the figure is as follows:

31- bottleneck 32- external screw thread 33- horn mouth

Specific embodiment

As shown in FIG. 1 to 3, a kind of improvement Tissue Culture Flask, including body 1, transition part 2 and bottleneck 3, transition part 2 are held in the mouth Body 1 and bottleneck 3 are connect, body 1 is along 2 Stepwize Shrink of transition part to bottleneck 31.

Body 1 is rectangle body, including bottom wall 11, top 13 and three side walls 12, and wherein bottom wall, roof are opposite Two side walls constitute the main body of body and are connected with transition part, and transition part includes four and the integrally formed side of body, wherein The bottleneck medial surface for being connected the medial surface of bottom wall and being connected with the medial surface is extended straight until bottle mouth position, and no turnover is ascended the throne In on same straight line, other three sides of transition part and bottleneck joining place are in certain radian, transition part and bottom wall into 160~165 ° Angle.

Bottleneck 31 and go out a turned-out arc-shaped horn mouth 33 is arranged apart from top edge 1mm or so, horn mouth is maximum straight It is less than external thread diameter at diameter.

Bottleneck 3 is cylinder, and external screw thread 32 is arranged, and bottle cap (not shown) and bottleneck thread cooperate, and bottleneck is a length of 1.5~2.5cm, bottleneck diameter are 1~2cm, and the diameter at horn mouth maximum gauge is greater than 0.15~0.25cm of bottleneck diameter, In present embodiment, most preferably, neck length 2cm, bottleneck diameter 1.5cm, collar extension end loudspeaker maximum gauge 1.7cm.The long * of bottle body Wide * high=5cm*4cm*2cm, wherein length and width can be with random fluctuation.

The foregoing is merely the specific implementation cases of the utility model patent, but the technical characteristic of the utility model patent is simultaneously Not limited to this, in the field of the utility model, made changes or modifications all cover any those skilled in the relevant art Among the scope of the patents of the utility model.
