Description
Technical field
This utility model relates to the segregation apparatus that experiment is biological, and a kind of large-scale experiment is female and children
Segregation apparatus.
Background technology
Large-scale (Daphnia magna) is the one way of life biology at natural water area, be plankton, zooplankton,
Arthropoda, crustacean guiding principle, Branchiopoda, double Leptostraca, dish intestinal water Superfamily, water belong to.Large-scale because having life week
Phase is short, breeding is fast, economical, be conveniently easy to get, be prone in advantages such as laboratory cultures, and it has important in aquatic ecosystem
Status, therefore suffer from numerous country toxicology worker attention.Large-scale is that sensitivity is relatively strong, the most representational one
Plant zooplankton, become a kind of code test biological, be widely used in the research of aquatic toxicology.At present, ISO
Standard, OECD guide, U.S. EPA standard and China's GB all relate to the standard of large-scale growth inhibited and breeding.
In large-scale incubation, due to fertility very strong, need mother to be separated with children frequently, with
Guarantee that normal growth, the method that tradition separates typically use suction pipe to siphon away children or mother reaches to separate purpose, or directly use
It is female and young that screen cloth filters separation.The method inhaled with suction pipe is extremely inefficient, and directly uses the mode of strainer filtering to filter point
It is easy to hurt mother and children from female and children method so that follow-up cultivation occurs unhealthy mother.
Utility model content
For above-mentioned weak point of the prior art, this utility model aims to provide one can be convenient and swift and will not
The female segregation apparatus with children of large-scale experiment that female and children are damaged.
For solving above-mentioned technical problem, the segregation apparatus that large-scale experiment of the present utility model is female and young, including
Using the filter cup made of glass material and U-shaped conduit, described filter cup lower end offers the first under shed, described filter cup
Lower end is connected with one end of described U-shaped conduit, is provided with nylon filter at 3～5cm below its junction.
A diameter of 1.5mm of described nylon filter mesh.
On described first under shed, coupling is provided with the first plug, described first plug and the flexible connection of the first under shed.
Offer the second under shed bottom described U-shaped conduit, mate with described second under shed and be provided with the second plug, institute
State the second plug and the second under shed is flexibly connected.
Described filter cup upper port is big, and lower port is little.
The other end of described U-shaped conduit is provided with the 3rd plug, and described 3rd plug is flexibly connected with U-shaped conduit.
The segregation apparatus that large-scale experiment of the present utility model is female and young, owing to it is in addition to nylon filter, for
All-glass construction, to culture fluid do not result in secondary pollution, device is simple, it is easy to operation；Filter cup lower end is opened for first time
The female derivation after separating is easy in the setting of mouth；Because of female body a length of 2.2～4.8mm, and children is the least, so this practicality
The nylon filter in novel employing a diameter of 1.5mm aperture, can well be by female and young for the female and separation of children
Separate, female and children will not be caused any harm simultaneously；Filter cup uses upper port big, the design that lower port is little, just
Dismounting and taking-up in nylon filter are cleaned；The setting of the second under shed of U-shaped conduit, it is simple to the children after separating is all
Deriving, nylon filter is arranged below, at U-shaped conduit 3～5cm, to control the water level of water in filter cup, preventing mother and children
In separation process, in filter cup, solution leaks dry completely and damages separating mother；First plug, the second plug and the 3rd
The setting of plug, solves regular tap and easily forms the problem at dead angle, simultaneously the convenient opening and airtight of selecting according to demand.
Accompanying drawing explanation
Fig. 1 is the structural representation of the female segregation apparatus with children of large-scale experiment of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
As it is shown in figure 1, large-scale experiment of the present utility model is female and the segregation apparatus of children, including using glass
Filter cup 1 that material is made and U-shaped conduit 2, described filter cup 1 lower end offers the first under shed 3, described filter cup 1 lower end
It is connected with one end of described U-shaped conduit 2, below its junction, is provided with nylon filter 4 at 3～5cm.Owing to it is except nylon
Outside drainage screen 4, for all-glass construction, to culture fluid do not result in secondary pollution, device is simple, it is easy to operation；Filter cup 1
The female derivation after separating is easy in the setting of lower end the first under shed 3；Because of female body a length of 2.2～4.8mm, and children is very
Little, so this utility model uses the nylon filter 4 separation for mother with children in a diameter of 1.5mm aperture, can be very
Good separates mother and children, will not cause any harm female and children simultaneously.
Further, a diameter of 1.5mm in described nylon filter 4 hole.On described first under shed 3, coupling is provided with the
One plug 5, described first plug 5 is flexibly connected with the first under shed 3.
Further, bottom described U-shaped conduit 2, offer the second under shed 6, mate setting with described second under shed 6
The second plug 7, described second plug 7 is had to be flexibly connected with the second under shed 6.The setting of the second under shed 6 of U-shaped conduit 2, just
Children after separating all derives, and nylon filter 4 is arranged below, at the 3～5cm of U-shaped conduit 1, to control filter cup
The water level of water in 1, prevents female leakage completely with solution in filter cup 1 in children's separation process from doing and causing wound to separating mother
Evil.
Further, described filter cup 1 upper port is big, and lower port is little.Filter cup 1 uses upper port big, and lower port is little
Design, it is simple to dismounting and the taking-up of nylon filter 4 are cleaned.
Further, the other end of described U-shaped conduit 2 is provided with the 3rd plug 8, described 3rd plug 8 and U-shaped conduit
2 are flexibly connected.First plug the 5, second plug 7 and the setting of the 3rd plug 8, solves regular tap and easily forms asking of dead angle
Topic, the simultaneously convenient opening and airtight of selecting according to demand.
Concrete, this utility model in use, by culture fluid be poured into filter cup 1 from the upper port of filter cup 1
In, after the filtration of nylon filter 4, female derivation in the first under shed 3, children is then filtered in U-shaped conduit 2, point
Children after completing derives through the second under shed 6, completes the female and separation of children.
