Abstract
The invention relates to a novel silica gel plug special for a conical flask. The silica gel plug consists of a bottle plug main body and a sand chip, is especially used for sealing the mouth of the conical flask, and can seal the mouth of the conical flask in all directions, so that an open area of the flask is sealed, and an outer edge area of the mouth of the flask can also be sealed. The silica gel plug has the advantages of high sealing property, ageing resistance, high temperature and high pressure resistance, low temperature resistance, corrosion resistance, recyclability and the like, and is easy and convenient to use, so that the silica gel plug is ideal and practical for the conical flask.
Description
Technical field the present invention relates to a kind of special-purpose conical flask novel silicon plug, is comprised of bottle stopper main body and core sheet, and the sealing that is specifically designed to conical flask is processed, and can seal in all directions the bottleneck of conical flask.Not only seal the uncovered zone of flask, also can seal the zone, outer of flask mouth.The present invention makes the closed routine simple and fast of flask, integrates sealing, resistance to ag(e)ing, high temperature high voltage resistant, lower temperature resistance, corrosion resistance, is the practical bottle stopper invention of new type ideal.
The background technology conical flask is of long duration as the use of experiment consumptive material, is widely used in chemical experiment, biological experiment, the medical experiment.Conical flask uncovered, its main application are reagent preparation, splendid attire reactant, heat treated sample, quantitative analysis titration.Usually prepare and hold bacteria culture media in medical science and the biological experiment with conical flask.Because the characteristic of its uncovered uncovered, after culture medium was finished in configuration in conical flask usually, at its mouth neck portion beyond the Great Wall common conical flask band edge plug or cotton yarn bottle stopper, adding lid layer brown paper, to carry out high pressure steam sterilization for subsequent use.No matter conical flask band edge plug or cotton yarn bottle stopper all can only seal the uncovered zone of flask, to the outer of flask mouth unobstructed sealing process then.Therefore, before autoclaving, must wrap up brown paper, tie up cotton rope and carry out Omnidirectional enclosed.Although the using method sealing effect of this classics is reliable, operate comparatively loaded down with trivial detailsly, also need use brown paper and strand materials, must untie first cotton rope during use, take behind brown paper cap and the bottle stopper again row and topple over culture medium.In order to increase work efficiency, reduce unnecessary operating procedure, we have invented a kind of special-purpose conical flask novel silicon plug.This kind plug can omnibearing sealing conical flask mouth neck portion, not only can seal the uncovered zone of flask, also can seal the zone, outer of flask mouth.Only need a bottle stopper just can solve the sealing problem of flask, need not use brown paper, strand materials again, greatly simplified the sealing program of conical flask, use efficient and conveniently, sealing effectiveness is reliable.This invention has the advantages such as stable sealing property, fabulous heat-resisting resistance to low temperature, suitable acid-proof alkaline, splendid ageing-resistant performance, nontoxic pollution-free, the property recycled.
Summary of the invention the invention is characterized in, described special-purpose conical flask novel silicon plug is comprised of bottle stopper main body and core sheet, can seal in all directions the bottleneck of conical flask.
The bottle stopper main body is comprised of chock plug, plug neck and annular flange.The plug neck is positioned under the chock plug coupled being integrated; Chock plug and plug neck inside are the hollow axial cavity that mutually connects; The annular flange is positioned at chock plug and plug neck intersection, radially around, extend axially; The structure that annular has been set up the convex edge on the flange is convenient to fixedly plug, sealing conical flask bottleneck outer wall, is prevented from leaking gas.Chock plug, plug neck and annular flange form the bottle stopper main body jointly by the die pressing disposal molding.The core sheet is disc-shaped, is positioned at the chock plug top, and is tight-lipped close chimeric with the inner chamber at chock plug top.The core sheet has higher intensity and gas permeability, is convenient to plug at the laggard horizontal high voltage steam sterilizing of sealing flask mouth, avoids occuring cold and hot gas expansion plug jumping.After in conical flask, preparing required culture medium, hold annular flange glue stopper neck is filled in the conical flask bottleneck, after appropriateness is pressed annular flange turned over and encase bottleneck downwards and get final product.The conical flask of jumping a queue is put into autoclave sterilizer carry out sterilization.The complete rear taking-up conical flask of sterilizing twines aseptic sealing strip on the surface of core sheet, closing cock crown section, in case the various bacteriums in the isolated external environment, the holding time of Extending culture base.During culture medium in toppling over conical flask, only need take whole bottle stopper, directly topple over after burning bottleneck.After culture medium is finished using, conical flask bottleneck and glue stopper neck successively after alcolhol burner flame burns, are got final product such as front sealing.Conical flask after the sealing sterilization can be used as reagent and holds a bottle long preservation, also can be used as the test reaction bulb and participates in chemical test, biological test, medical experiment, Disinfection test.
The present invention has following advantage: 1) sealing property is superior, and sealing effect is reliable; 2) high temperature resistant 200 ℃, high pressure resistant (not collapsing plug), good permeability; 3) harmful DDGS such as not leaded, mercury, arsenic, barium, asepsis environment-protecting; 4) neutrality is with institute's installed reagents Fails To Respond; 5) culture of bacteria, Leptospira, ureaplasma urealyticum, the speed of growth is all identical with tester with increment; 6) the naked light sterilization is missing of ignition, easy to clean; 7) still flexible under-80 ℃ of low temperature.
The present invention is described in further detail below in conjunction with embodiment for the specific embodiment:
After in conical flask, preparing required culture medium, hold annular flange glue stopper neck is filled in the conical flask bottleneck, after appropriateness is pressed annular flange turned over and encase bottleneck downwards and get final product.The conical flask of jumping a queue is put into autoclave sterilizer carry out sterilization.The complete rear taking-up conical flask of sterilizing twines aseptic sealing strip on the surface of core sheet, closing cock crown section.During culture medium in toppling over conical flask, only need take whole bottle stopper, directly topple over after burning bottleneck.After culture medium is finished using, conical flask bottleneck and glue stopper neck successively after alcolhol burner flame burns, are got final product such as front sealing.
