Abstract
The utility model discloses a kind of test tube plug of applicable sizes test tube, belong to consumptive material field, laboratory; Comprise column cock body, pencil core, elastic spacing sealing ring, column cock body is tapered from top to bottom, and is provided with the ring groove of the different inner diameters around side from top to bottom; Elastic spacing sealing ring can closely be socketed in ring groove, and it has band; Column cock body is axially arranged with a through hole, places pencil core in through hole; The utility model test tube plug is applicable to the test tube of multiple different size specification, reduces consumptive material use amount, saves cost, avoid idle laboratory consumptive material, and the test tube of sizes can be general, brings conveniently to experiment, is easy to promote.
Description
Technical field
The utility model discloses a kind of test tube plug, belong to consumptive material field, laboratory; Specifically a kind of test tube plug of applicable sizes test tube.
Background technology
Test tube, the instrument that laboratory is conventional, is commonly used to the reaction vessel as a small amount of reagent in chemical experiment, uses when normal temperature or heating.In Bioexperiment, be commonly used for the container cultivated in microorganism, carry out activation or other cultivations of microorganism.Be no matter chemical experiment or Bioexperiment time, sometimes all can use test tube plug, manufacture a relatively airtight space to test tube.Especially during microorganism is cultivated, need to add test tube plug to test tube mouth, both can filtered air, living contaminants can be prevented again, and the evaporation of culture medium moisture can be slowed down, current existing test tube plug is self-control tampon or commercially available test tube plug substantially, self-control tampon is breathed freely best, but easily distortion is lost shape, need to change after using several times, always need to make, cumbersome and damage material very fast, and although commercially available test tube plug is longer for service time, there is various use specification, but differ larger between all size, cannot be general, laboratory needs the test tube plug buying all specifications when using, comprise the test tube plug of the specification that is of little use, increase consumptive material cost, the utility model provides a kind of test tube plug of applicable sizes test tube, test tube plug is applicable to the test tube of multiple different size specification, reduce consumptive material use amount, save cost, avoid idle laboratory consumptive material, and the test tube of sizes can be general, bring conveniently to experiment, be easy to promote.
Summary of the invention
The utility model, for this problem of test tube plug not being applicable to sizes test tube at present, provides a kind of test tube plug of applicable sizes test tube, and the test tube being applicable to laboratory different size uses, and is easy to promote.
The concrete scheme that the utility model proposes is:
A test tube plug for applicable sizes test tube, comprise column cock body, pencil core, elastic spacing sealing ring, column cock body is tapered from top to bottom, and is provided with the ring groove of the different inner diameters around side from top to bottom; Elastic spacing sealing ring can closely be socketed in ring groove, and it has band; Column cock body is axially arranged with a through hole, places pencil core in through hole.
Preferred described ring groove arranges 3-7 bar.The quantity of ring groove also can be set according to actual conditions, the internal diameter of such as test tube, length etc.
The external diameter of the uppermost ring groove of described column cock body is 25-38mm, and the external diameter of nethermost ring groove is 10-20mm.Elastic spacing sealing ring coordinates uppermost ring groove, is applicable to comparatively Boiling tube and uses, coordinate nethermost ring groove, is applicable to comparatively small test tube and uses.
Described column cock body is that polypropylene or silica gel make, and described elastic spacing sealing ring is that silica gel makes.Test tube plug also can adopt the material of other corrosion-and high-temp-resistants to make, if use in Bioexperiment, does not produce the requirement of harmful substance under demand fulfillment high temperature.
Usefulness of the present utility model is: test tube plug of the present utility model, comprise column cock body to be tapered from top to bottom, which is provided with the annular groove that diameter is different, for the test tube of different size, elastic spacing sealing ring can be connected in the annular groove of different-diameter, sealing test tube mouth; The band of elastic spacing sealing ring seals test tube mouth further, and column cock body is axially arranged with through hole, inside has pencil core, when preventing sterilizing, test tube plug jumps out due to pressure, the oxygen that microorganism can provide again microorganism to need when cultivating, and filtered air, prevent living contaminants, test tube plug is applicable to multiple different size test tube, not only reduce consumptive material use amount, save cost, the test tube of sizes can be general, facilitate experimenter and test use, be easy to promote.
