Abstract

A kind of branch pipe shaking flask includes shaking flask ontology, and the shaking flask ontology is conical flask, is equipped with bottleneck and bottle body, the side wall side of the bottle body is equipped with the long branch pipe being obliquely installed, the long branch pipe it is open-ended, and be connected with the bottle body, the long branch pipe and the shaking flask bottom surface are in ± 30 ° of angles；Utility model has the advantages that low cost, production easy to process；Not only had the advantages that the abundant dissolved oxygen of shaking flask, but have test tube can non-destructive determination reduced turbidity the advantages of；Structure is simple, easy to operate.

Description

Branch pipe shaking flask

Technical field

The utility model relates to a kind of branch pipe shaking flask, specifically one kind is suitable for shaken cultivation and carries out without sampling The shaking flask of reduced turbidity measurement, belongs to field of fermentation engineering.

Background technique

At present on laboratory level, multi-purpose shaking flask carries out strain culturing and generally requires when with turbidimetry for Determination increment Devastatingly sample.But if for aerobic bacteria, and existing with Tube propagation, and when with test tube method non-destructive determination reduced turbidity Tube propagation dissolved oxygen is insufficient and influences thalli growth.

Utility model content

To solve the above-mentioned problems, the utility model devises a kind of branch pipe shaking flask, is suitble to aerobic shaken cultivation, and lossless Reduced turbidity is measured by sampling, structure is simple, handling ease, and it is convenient and practical, the amount of labour is reduced, is improved work efficiency.

The technical solution of the utility model are as follows:

Branch pipe shaking flask, including shaking flask ontology, the shaking flask ontology are conical flask, are equipped with bottleneck and bottle body, the bottle body Side wall side is equipped with the long branch pipe that is obliquely installed, the long branch pipe it is open-ended, and be connected with the bottle body, it is described to draw money on credit Pipe is in ± 30 ° of angles with the shaking flask bottom surface.

Further, the long branch pipe is 5-100mL test tube, length 5-20cm.

Further, corresponding with the long branch pipe, the other side of the bottle body is short branch pipe, the short branch pipe with it is described Point-blank, one end of the short branch pipe is connected long branch pipe with the bottle body, and the other end is equipped with nozzle, convenient for cleaning length Branch pipe.

The short branch pipe is 5-100mL test tube, and length 1-5mL, the nozzle is located at the lower end of the short branch pipe.

Further, the nozzle is equipped with test tube plug or test tube cap.

Further, the test tube plug or test tube cap are the materials such as glass, metal, plastics, rubber, silica gel, are straight plug Or it is spiral.

Utility model has the advantages that low cost, production easy to process；Not only had the advantages that the abundant dissolved oxygen of shaking flask, but also Have test tube can non-destructive determination reduced turbidity the advantages of；Structure is simple, operates, conveniently, and the design of short branch pipe, and long branch pipe is made to be more convenient for Cleaning.

The utility model is described in further detail with reference to the accompanying drawings and examples.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model embodiment；

In figure: 1. shaking flasks, 2. long branch pipes, 3. short branch pipes, 4. test tube plugs or test tube cap.

Specific embodiment

The preferred embodiment of the utility model is illustrated below, it should be understood that preferred embodiment described herein It is only used for describing and explaining the present invention, is not used to limit the utility model.

Embodiment 1

As shown in Figure 1, a kind of branch pipe shaking flask, including shaking flask 1, long branch pipe 2, short branch pipe 3 and test tube plug or test tube cap 4, institute Stating shaking flask 1 is conical flask, and total measurement (volume) can be the various capacity such as 50-5000mL, and the long branch pipe 2 is 5-100mL test tube, length For 5-20cm, the short branch pipe 3 is 5-100mL test tube, length 1-5mL, long branch pipe 2 and short branch pipe 3 point-blank, with Shaking flask bottom surface is in ± 30 ° of angles, and the test tube plug or test tube cap are the materials such as glass, metal, plastics, rubber, silica gel, straight plug Or it is spiral.

When processing, to perforation on position that triangular flask is adapted within the scope of 3-50cm, test tube is truncated into two sections, length pipe It is respectively welded on the hole of two sides with short test tube, short branch pipe additional examination pipe close or test tube cap, equipment install.
