Abstract
This utility model provides and a kind of replaces the novel inversion pipe of little Du pipe in lactose fermentation tube, and including conical tube and the cylinder of upper end of lower end, described conical tube lower end is airtight, semicircular in shape, and upper end open is connected with cylindrical member at one end.Described cylinder other end opening, opening section and described cylindrical cross section are 30 °～60 °.Described conical tube high 10～12mm, described conical tube open cross-section diameter is identical with described cylindrical cross section diameter, is 5～8mm, described cylinder height 20～25mm.Described novel inversion pipe is transparent plastics material, can pass through autoclaving.Described novel inversion tube opening inclined design is conducive to collection and confinement of gases, and upper end uses conical shell to facilitate aerogenesis to observe, and uses plastic material to have with low cost, there is not the advantage scratching operator.This utility model is adapted to the bacteriologic test such as coliform, colibacillus of excrement and uses, and is also adapted to the test of other saccharides of bacterial fermentation and uses.
Description
Technical field
This utility model relates to laboratory equlpment technical field, a kind of replaces little Du pipe in lactose fermentation tube
Novel inversion pipe.
Background technology
During inspection coliform, LST and BGLB meat soup pipe generally uses glass Du Shi tubule (6mm × 30mm) as being inverted
Pipe, in order to observe the situation of bacterial fermentation lactose aerogenesis.Owing to the Du Shi tubule mouth of pipe is little, inspection concentration or the bigger sample of viscosity
During such as milk powder, lip pomade, the mouth of pipe is easily stuck with paste by sample, adds that glass is heavier, sinks at the bottom of pipe, is unfavorable for collection and confinement of gases.Produce if meeting
Tolerance is on the low side, then glass Du Shi tubule is difficult to float, and especially during detection dark colour sample such as eye shadow, is difficult to see Du Shi tubule clearly
The most whether there is bubble, be easily caused erroneous judgement.It addition, the glass Du Shi tubule mouth of pipe is little, it is difficult to clean up, Glass breadks easily, easily
Cause operator to scratch, there is bio-safety hidden danger.
Summary of the invention
The deficiency that this utility model exists for above-mentioned glass Du Shi tubule, it is provided that one facilitates aerogenesis to observe, price is low
The novel inversion pipe of little Du pipe in the replacement lactose fermentation tube that honest and clean, operation is safe.
This utility model solve its technical problem be the technical scheme is that offer a kind of disposable novel fall
Putting pipe, including conical tube and the cylinder of lower end of upper end, described conical tube lower end is airtight, semicircular in shape, and conical tube upper end is opened
Mouth is connected with cylindrical member at one end, described cylinder other end opening, described cylinder opening section and described cylindrical cross section
In 30 °～60 °.Described conical tube high 10～12mm, described conical tube open cross-section diameter is straight with described cylindrical cross section
Footpath is identical, is 5～8mm, described cylinder height 20～25mm.Described novel inversion pipe is transparent plastics material, can pass through high pressure
Sterilizing.
The utility model has the advantage of: described novel inversion pipe uses inclined-plane opening, add inversion pipe and collect gas
Area, can more preferably assemble bacterial fermentation lactose produce gas.Described novel inversion pipe lower end uses conical tube moulding, favorably
In the observation to a small amount of gas.Described novel inversion pipe uses plastic material, lightweight, when populated with gas in pipe, easily
Make vertebral body portion, inversion pipe lower end expose liquid level, result is observed very clear.Described novel inversion pipe uses plastic material, tube wall
Thickness≤1mm, with low cost, there is not the bio-safety hidden danger scratching operator.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In Fig. 1,1 conical tube, 2 cylinders, 3 conical tube closed lower end, 4 cylinder inclined-planes are opened
Mouthful.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limit scope of the present utility model.Any made within spirit of the present utility model and principle repair
Change, within equivalent and improvement etc. should be included in claims of the present utility model.
Embodiment 1, such as Fig. 1, a kind of novel inversion pipe, including conical tube and the cylinder of lower end of lower end, described circular cone
Pipe lower end is airtight, semicircular in shape, and conical tube upper end open is connected with cylindrical member at one end, described cylinder other end opening, preferably
Cylinder opening section and described cylindrical cross section are 45 °, and preferably conical tube height is 10mm, preferably cylindrical cross section
Interior diameter is 6mm, and described cylinder length is 22mm.
Described novel inversion pipe is transparent plastics material, pipe thickness≤1mm, can pass through 121 ° of autoclavings.
Claims (3)
1. replace a novel inversion pipe for little Du pipe in lactose fermentation tube, including conical tube and the cylinder of upper end of lower end,
It is characterized in that: described conical tube lower end is airtight, semicircular in shape, conical tube upper end open is connected with cylindrical member at one end, described circle
