Description

A kind of insect worm's ovum embryo, newly hatched larvae experiment disinfection mesh screen

Technical field

The utility model is related to a kind of Bioexperiment utensil more particularly to a kind of insect worm's ovum embryo, newly hatched larvae experiments Sterilize mesh screen.

Background technology

In recent years, Insect cellculture technology has been widely used in Entomological Physiology, insect pathology, insect toxicity The fields such as, molecular genetics, auxology, endocrinology.Embryo of the mother cell respectively from insect that establishes insect cell line, Newly hatched larvae, ovary, spermary, haemocyte, fat-body, middle intestines etc..Wherein embryonic cell regeneration potential is high, and has been generally acknowledged that and newly incubate There are a large amount of cells with in-vitro multiplication ability in larva body.Therefore, the cell line established using insect embryo and newly hatched larvae At most, account for about more than half of institute's established cell line.

It has to pass through for the insect worm's ovum of cell culture and sterilizes completely and then avoid polluting.Some worm's ovums be from soil or Sieve picks up acquisition in insect excrement, and Some Insects worm's ovum chorion surface, with mucus, ovum wall speckles with soil or excrement, if disinfection It is not thorough and will result in partial embryonic cell contamination；And after thimerosal is taken out, worm's ovum adheres to sterilizing utensil bottom, worm's ovum Chorion is relatively thin, is easily broken, and is hardly transferred in another vessel.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of easy to operate, significant insect worm's ovums of Disinfection Effect Embryo, newly hatched larvae experiment disinfection mesh screen.

To solve the above problems, a kind of insect worm's ovum embryo described in the utility model, newly hatched larvae experiment disinfection mesh screen, It is characterized in that：The mesh screen includes the least radius outer layer sieve, secondary radius sieve, maximum radius sieve in concentric circles compass screen surface；It is described most Least radius inner layer is equipped in minor radius outer layer sieve to sieve；The secondary radius sieve is embedded with 2 isometric secondary radiuses along its perimeter and sieves receipts Drawstring, the rope length which reels rope are equal with the perimeter of the secondary radius sieve；The maximum radius sieve is set along its perimeter There are 2 isometric maximum radius sieves to reel rope.

The mesh size of the least radius outer layer sieve and the secondary radius sieve and maximum radius sieve is 20 ~ 60 Mesh.

The least radius outer layer sieve is consistent with the mesh size that the least radius inner layer sieves and mutually coincide.

The radius of the least radius outer layer sieve is 6 ~ 25cm.

The radius of the secondary radius sieve is 13.5 ~ 45cm.

The radius of the maximum radius sieve is 22.5 ~ 112.5cm.

The length that the maximum radius sieve reels rope sieves 1.5 times of perimeter for the maximum radius.

The drawstring port that described 2 isometric secondary radius sieves reel rope is set on the diameter both ends of the secondary radius sieve, and every Item time radius sieve, which reels rope head and the tail and is closed, to be connected.

The drawstring port that described 2 isometric maximum radius sieves reel rope is set on the diameter both ends of maximum radius sieve, And every radius sieve reels rope head and the tail and is closed and is connected.

It is 0.5mm that the secondary radius sieve, which reels the thickness that rope reels rope with maximum radius sieve,.

The utility model has the following advantages compared with prior art：

1st, the utility model reels rope by pulling time radius sieve, and insect worm's ovum is made to concentrate on by secondary radius sieve and most smaller part Diameter screen banks into closed area in, which can be totally submerged in filling in 30 ~ 150mm culture dishes of thimerosal；Pass through twitch Maximum radius sieve rope is securable to culture dish bottom, is nested in culture dish lid, not only convenient for picking, and improves work efficiency, Disinfection Effect is notable.

2nd, the utility model is easy to operate, reusable, is suitble to moist heat sterilization.

Description of the drawings

Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is the structure diagram of the utility model.

In figure：1-least radius outer layer sieves；2-secondary radius sieve；3-maximum radius is sieved；4-least radius inner layer sieves； 5-secondary radius sieve reels rope；6-maximum radius sieve reels rope.

Specific embodiment

As shown in Figure 1, a kind of insect worm's ovum embryo, newly hatched larvae experiment disinfection mesh screen, the mesh screen are included in concentric rotary strainer Least radius outer layer sieve 1, secondary radius sieve 2, the maximum radius sieve 3 in face.

Least radius inner layer, which is equipped with, in least radius outer layer sieve 1 sieves 4；Secondary radius sieve 2 is embedded with 2 isometric times along its perimeter Radius sieve reels rope 5, and the rope length which reels rope 5 is equal with time perimeter of radius sieve 2；Maximum radius sieves 3 along its week It is long to reel rope 6 equipped with 2 isometric maximum radius sieves.

Wherein：Least radius outer layer sieve 1 and the mesh size of time radius sieve 2 and maximum radius sieve 3 are 20 ~ 60 mesh.

Least radius outer layer sieve 1 is consistent with the mesh size of least radius inner layer sieve 4 and mutually coincide.

The radius of least radius outer layer sieve 1 is 6 ~ 25cm.The radius of secondary radius sieve 2 is 13.5 ~ 45cm.Maximum radius sieve 3 Radius be 22.5 ~ 112.5cm.

Maximum radius sieve reels 1.5 times of the length of rope 6 for maximum radius 3 perimeters of sieve.

The drawstring port that 2 isometric secondary radius sieves reel rope 5 is set on the diameter both ends that time radius sieves 2, and every time half Diameter sieve, which reels rope head and the tail and is closed, to be connected.

The drawstring port that 2 isometric maximum radius sieves reel rope 6 is set on the diameter both ends of maximum radius sieve 3, and every Secondary radius sieve, which reels rope head and the tail and is closed, to be connected.

It is 0.5mm that secondary radius sieve, which reels the thickness that rope 5 reels rope 6 with maximum radius sieve,.

Above-mentioned sieve and rope are all high temperature resistant material.

In use, drawing time radius sieve reels rope 5, insect worm's ovum is made to concentrate on by secondary radius sieve 2 and least radius outer layer In the closed area of 1 composition of sieve, which can be totally submerged in filling in 30 ~ 150mm culture dishes of thimerosal；By twitching most Large radius sieve reels rope 6 and is securable to culture dish bottom, and be nested in culture dish lid, then carries out picking.It is sieved by changing Net radius size and ratio can design the disinfection sieve suitable for the culture dish of various specifications.
