Description
Technical field
This utility model relates to biological technical field, is specifically related to a kind of orifice plate combinative structure.
Background technology
Orifice plate is the experimental tool carrier that biological technical field is important, and common includes that 4 row × 6 arrange (adding up to 24 holes), 6 row
× 8 row (adding up to 48 holes), 8 row × 12 row (adding up to 96 holes), 12 row × 16 row (adding up to 192 holes), 16 row × 24 row (add up to 384
Hole).Wherein in the basic research of biological pesticide, orifice plate is commonly used for the toxicity test of toxin, specifically will be containing the denseest
The insect feedstuff of degree toxin is laid in bottom orifice plate, treats that feedstuff is dried, puts into a certain amount of insecticide, close the lid, be placed in suitable
Preferably temperature is cultivated and is observed.But, between the lid of traditional orifice plate and main part, gap is bigger, it is impossible to closes each hole, easily makes
Obtain insecticide to run helter-skelter, cause experiment to be difficult to or experimental data is inaccurate.And use sealed membrane to carry out sealing and need at least two-layer,
And often hole must individually be sealed, needs the most raw survey when, workload is big, the longest, and owing to sealed membrane is thin, depends on
So there is minority insecticide can break by the teeth sealed membrane, thus climb out of and run helter-skelter, there is the drawback that experimental data is inaccurate.
As improvement, the Chinese utility model patent of Application No. 201420735001.6 discloses a kind of many condition micropore
Board combining structure, including microwell plate, lid and temperature controller, the micro-pore shape of described microwell plate includes circle, regular polygon,
In the micropore of same shape, at least a hole is provided with baffle plate；Rubber blanket it is provided with inside four limits of described lid, described lid
Inside top is provided with the groove of a circle rectangular configuration, and the described lid under lid dress state is closely tied with microwell plate by rubber blanket
Close.The orifice plate combinative structure of this utility model is by arranging rubber blanket inside four limits of lid, although solve to a certain extent
The clearance issues of lid and main body, but owing to lid is one piece of integral slab, each hole in orifice plate is not carried out individually
Sealing, when this orifice plate combinative structure for toxin toxicity test test time, the insecticide in hole still can the most each hole it
Between run helter-skelter, affect experimental data accuracy.
A kind of can effectively prevent insecticide from running helter-skelter and simple and practical orifice plate combinative structure therefore, it is necessary to invent.
