Abstract

The utility model discloses a fermentation test tube, including the cylindrical shape body of flat mouthful round bottom, body open -top, the upper end of body lateral wall is provided with the transversal branch pipe, and the port that the body was kept away from to transversal branch pipe and body intercommunication, transversal branch pipe is provided with first stopper, and the body bottom is provided with the bottom branch pipe, and the port that the body was kept away from to bottom branch pipe and body intercommunication, bottom branch pipe is provided with the second stopper, and central groove is carved with in the center department of body lateral wall. The utility model relates to a fermentation test tube, simple structure, convenient operation, earlier good first stopper of stopper and second stopper during the use, the material that will ferment is again packed into in the test tube main part through test tube main part opening, treats the fermentation back that finishes, the observation fermentation, if surpass central groove, can follow transversal branch pipe or bottom branch pipe pour all can, without surpassing central groove, then pour through the bottom branch pipe, can effectively reduce flow losses.

Description

A kind of fermentation tube

Technical field

This utility model belongs to technical field of experiment equipment, is specifically related to a kind of fermentation tube.

Background technology

Test tube is the instrument that chemical laboratory is conventional, and test tube serves as the reaction vessel of a small amount of reagent, uses when room temperature or heating.Fermentation tube is the one of test tube, is a kind of container being mainly used to be used as carrying fermented material.

Existing fermentation tube is designed to the flat mouth test tube that simple bore is thin and short mostly, and major part fermentation tube is the design of round bottom shape, fermented product often volume only accounts for the very small part of test tube volume, if and pour out fermented material from test tube upper end open and frequently can lead to a large amount of residue and be retained in inboard wall of test tube, cause and greatly waste, and existing fermentation tube only only one of which opening.

Utility model content

The purpose of this utility model is to provide a kind of fermentation tube, solves existing test tube and pours out the problem that during fermented product, loss amount is big.

This utility model be employed technical scheme comprise that, a kind of fermentation tube, including the cylinder barrel shaped body of flat mouth round bottom, bodies top opening, the upper end of body sidewall is provided with horizontal arm, horizontal arm connects with body, horizontal arm is provided with the first stopper away from the port of body, and body bottom portion is provided with bottom manifold, and bottom manifold connects with body, bottom manifold is provided with the second stopper away from the port of body, and center groove is carved with in the center of body sidewall.

Feature of the present utility model also resides in,

The horizontal arm distance from body top is the 1/3 of body length.

First stopper and the mutual interference fit of horizontal arm.

Second stopper and the mutual interference fit of bottom manifold.

The diameter of horizontal arm is less than the diameter of body.

The diameter of bottom manifold is less than the diameter of body.

First stopper and the second stopper all adopt silica gel stopper.

The beneficial effects of the utility model are: this utility model one fermentation tube, simple in construction, easy to operate, first it is stoppered the first stopper and the second stopper during use, this is internal again by test tube body openings, fermented material to be loaded test tube, after waiting to ferment, observe fermented product, if beyond center groove, can pour out from horizontal arm or bottom manifold, without beyond center groove, then poured out by bottom manifold, be effectively reduced flow losses.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of fermentation tube of this utility model.

In figure, 1. body, 2. horizontal arm, 3. bottom manifold, 4. the first stopper, 5. the second stopper, 6. center groove.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.

This utility model one fermentation tube, as shown in Figure 1, cylinder barrel shaped body 1 including flat mouth round bottom, body 1 open top, the upper end of body 1 sidewall is provided with horizontal arm 2, the horizontal arm 2 distance from body 1 top is the 1/3 of body 1 length, horizontal arm 2 connects with body 1, horizontal arm 2 is provided with the first stopper 4 away from the port of body 1, bottom manifold 3 it is provided with bottom body 1, bottom manifold 3 connects with body 1, and bottom manifold 3 is provided with the second stopper 5 away from the port of body 1, and center groove 6 is carved with in the center of body 1 sidewall.

Body 1, horizontal arm 2, bottom manifold 3 are by glass manufacture, and anti-corrosion capability is good.

The diameter of horizontal arm 2 and bottom manifold 3 is respectively less than the diameter of body 1, facilitates the overall manufacture of test tube.

First stopper 4 and the second stopper 5 are by silica gel manufacture, good airproof performance.

First stopper 4 and the horizontal mutual interference fit of arm 2, the second stopper 5 and the mutual interference fit of bottom manifold 3, can effectively prevent from revealing.

The first stopper 4 and the second stopper 5 first it is stoppered during use, again fermented material is loaded in body 1 by body 1 opening, after waiting to ferment, observe fermented product, if beyond center groove 6, poured out from horizontal arm 2 or bottom manifold 3, without beyond center groove 6, then poured out by bottom manifold 3, be effectively reduced flow losses.
