Description

A kind of constant volume nutrient culture media measure device
Technical field
The constant volume nutrient culture media measure device that the utility model relates to a kind of easy to operate practicality, cost is low, precision is high, belongs to agronomic trials instrument field.
Background technology
Along with China's rapid economic development, scientific research technology is also being constantly brought forth new ideas, and is all also in virgin state for many underlying instruments necessary in laboratory, although some novel instrument technically has certain innovation, but price is very expensive.When toxicity test being carried out to phytopathogen in indoor; accurately measuring 9ml nutrient culture media is the most basic operation; common laboratory all uses the measuring cup of 10ml to measure; but because measuring cup mouth is larger; easily spill, and nutrient culture media will be set in the inside soon, once do effect experiment in enormous quantities; a large amount of measuring cups will be needed, often can cause experimental error.Although market is sold 10ml liquid-transfering gun, price costly.In addition once break doing 10ml liquid-transfering gun in the process of testing, the operation of whole experiment will be had a strong impact on.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of constant volume nutrient culture media measure device, and structure is simple, operation and easy to loading and unloading, and practicality is laborsaving, and cost is low, and precision is high, not fragile, to overcome the deficiency of prior art problem.
The technical scheme that the utility model is taked is: a kind of constant volume nutrient culture media measure device, comprise syringe and constant volume import rifle head, described syringe is injector for medical purpose with a scale, injection port compact siro spinning technology constant volume import rifle head upper end, lower end, and described constant volume import rifle head is bullet shaped profile structure.
Described syringe and constant volume import rifle head junction adopt rubber plug to realize being tightly connected, and rubber plug have the hole identical with injection port external diameter, are closely enclosed within injection port place, adopt rubber plug, being tightly connected of constant volume import rifle head can be realized, be connected firmly, easy to loading and unloading, not fragile.
Described syringe adopts 20ml capacity injector for medical purpose, open ended reagent volume is far more than general 10ml syringe, and suction wants large, can draw the nutrient culture media of enough 10ml, constant volume import rifle head adopts 10ml rifle head, for testing conventional nutrient culture media amount of capacity, precision is high, can improve test efficiency, greatly obtain test findings, minimum for test impact, easy to operate practicality, and can take off easily and carry out sterilization treatment.
Described rubber plug adopts 10ml injector for medical purpose inner carrier rubber chock plug, is convenient to obtain, is easy to installation and removal, good airproof performance in laboratory.
The beneficial effects of the utility model: compared with prior art, the utility model adopts injector for medical purpose with a scale and constant volume import rifle head, achieve measuring of fixed capacity nutrient culture media, this device operation and easy to loading and unloading, practicality is laborsaving, precision is high, and have that structure is simple, cost is low, the feature of economical environment-protective, solve exist in prior art not easy to operate, error is large, expensive, flimsy problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is rubber plug schematic diagram of the present utility model.
In figure, 1-syringe, 2-rubber plug, 3-constant volume import rifle head.
Embodiment
As shown in Fig. 1 ~ Fig. 2, a kind of constant volume nutrient culture media measure device, comprise syringe 1 and constant volume import rifle head 3, described syringe 1 is injector for medical purpose with a scale, injector for medical purpose is easy to buy, price is low, structure is simple, injection port compact siro spinning technology constant volume import rifle head 3 upper end, lower end, described constant volume import rifle head 3 is bullet shaped profile structure, import rifle head is for using high-purity polypropylene material, smooth surface, less to the absorption of liquid, liquid not easy to hang, and domestic with the addition of partial regeneration polypropylene, extension liquid is serious, in addition, machining precision is also different, the mould and die accuracy of import is high, and strict control of quality in production run, can safeguard in time and repairing mould, and domestic considering for cost control, die quality and safeguard on all not fully up to expectations, constant volume import rifle head 3 can carry out autoclaving, have precision high, can reuse, feature that cost is low, adopt injector for medical purpose with a scale and constant volume import rifle head, achieve measuring of fixed capacity nutrient culture media, this device operation and easy to loading and unloading, practicality is laborsaving, precision is high, and have that structure is simple, cost is low, the feature of economical environment-protective, solve exist in prior art not easy to operate, error is large, expensive, flimsy problem.
Described syringe 1 adopts rubber plug 2 to realize being tightly connected with constant volume import rifle head 3 junction, rubber plug 2 has the hole identical with injection port external diameter, is closely enclosed within injection port place, adopt rubber plug can realize being tightly connected of constant volume rifle head, be connected firmly, easy to loading and unloading, not fragile.
Described syringe 1 adopts 20ml capacity injector for medical purpose, open ended reagent volume is far more than general 10ml syringe, and suction wants large, can draw the nutrient culture media of enough 10ml, constant volume import rifle head 3 adopts 10ml rifle head, for testing conventional nutrient culture media amount of capacity, precision is high, can improve test efficiency, greatly obtain test findings, minimum for test impact, easy to operate practicality, and can take off easily and carry out sterilization treatment.
Described rubber plug 2 adopts 10ml injector for medical purpose inner carrier rubber chock plug, is convenient to obtain in laboratory, and is easy to buy, and cost is low, is easy to installation and removal, good airproof performance.
During use, selecting 20ml injector for medical purpose to be connected with round-meshed rubber plug with 10ml constant volume import rifle head, quantitatively drawing 10ml nutrient culture media by pulling syringe piston, the nutrient culture media be drawn to is expelled in double dish and is used for the indoor pharmacy test of plant disease.The utility model has reasonable in design, simple to operate, practical laborsaving, precision advantages of higher, and the laboratory being particularly suitable for relating at plant pathology etc. microorganism cultivation is promoted the use of.
The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the scope that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
