Description

专用三角烧瓶新型硅胶塞[0001] 技术领域本发明涉及一种专用三角烧瓶新型硅胶塞,由瓶塞主体和砂芯片组成, 专门用于三角烧瓶的封口处理,可以全方位地封闭三角烧瓶的瓶口。 Erlenmeyer flask new dedicated plug of silica gel [0001] Technical Field The present invention relates to a new dedicated plug of silica gel Erlenmeyer flask, and a stopper body sand chips, designed for sealed to the Erlenmeyer flask, could be all closed Erlenmeyer flask bottle mouth. 不仅封闭烧瓶的敞口区域,还可封闭烧瓶口的外沿区域。 The flask was closed not only the open area, outer area of ​​the mouth of the flask may be closed. 本发明使烧瓶的封闭程序简单快捷,集密封性、耐老化性、耐高温高压性、耐低温性、耐腐蚀性于一体,是新型理想的实用型的瓶塞发明。 The present invention enables simple and quick procedure flask was closed, sealing set, aging resistance, high temperature high pressure resistance, low temperature resistance, corrosion resistance in one, is a new practical ideal cork invention. [0002] 背景技术三角烧瓶作为实验耗材的使用由来已久,广泛用于化学实验、生物学实验、医学实验中。 [0002] BACKGROUND Erlenmeyer flask and laboratory supplies as the use of long-standing, widely used in chemical experiments, biological experiments, medical experiments. 三角烧瓶无盖,其主要用途为配制试剂、盛装反应物、加热处理试样、定量分析滴定。 Erlenmeyer flask without lid, which is mainly used for reagent preparation, containing the reactants, heat-treated sample, quantitative analysis of titration. 医学和生物学实验中常常用三角烧瓶来配制和盛放细菌培养基。 Medical and biological experiments are often used to formulate Erlenmeyer flask and culture medium for bacteria bloom. 由于其敞口无盖的特性,通常在三角烧瓶内配置完成培养基后,在其口颈部塞上普通三角烧瓶带边胶塞或者棉纱瓶塞,加盖一层牛皮纸进行高压蒸汽灭菌备用。 Due to its characteristics without a lid open, after the completion of the culture medium is generally disposed at its neck flask equipped with a side of triangulation plug or plugs in the cotton stopper Erlenmeyer flask, covered with a layer of kraft paper standby autoclaved . 无论三角烧瓶带边胶塞还是棉纱瓶塞,都只能封闭烧瓶敞口区域,对烧瓶口的外沿则无遮挡封闭作用。 Whether Erlenmeyer flask with a cotton stopper or plug side, can only open area flask was closed, the outer edge of the mouth of the flask is closed no shielding effect. 因此,在高压灭菌之前必须包裹牛皮纸,捆扎线绳进行全方位封闭。 Therefore, it must be wrapped in brown paper before autoclaving, tying cord-round closed. 这种经典的使用方法虽然封闭效果可靠,但操作较为繁琐,还需用到牛皮纸和线绳材料,使用时必须先解开线绳,摘下牛皮纸帽和瓶塞后再行倾倒培养基。 This method, although using classical reliable sealing effect, but the operation is more complicated, and the need to use kraft strand material must be solved when using wire, kraft off line after pouring stopper cap and medium. 为了提高工作效率,减少不必要的操作步骤,我们发明了一种专用三角烧瓶新型硅胶塞。 In order to improve efficiency, reduce unnecessary steps, we invented a new dedicated Erlenmeyer flask plug of silica gel. 该种胶塞可以全方位的封闭三角烧瓶的口颈部,不仅可以封闭烧瓶的敞口区域,还可封闭烧瓶口的外沿区域。 This kind of stopper can be closed round the neck Erlenmeyer flask, the flask can be closed only open area, the outer edge region of the flask may be closed opening. 只需一个瓶塞就可解决烧瓶的封口问题,勿需再用牛皮纸、线绳材料,极大地简化了三角烧瓶的封口程序,使用快捷方便,密封效果可靠。 Only one stopper can solve the problem of sealing the flask, then Needless kraft paper, wire material, greatly simplifying the sealing procedure Erlenmeyer flask, quick and easy to use, reliable sealing effect. 该发明具有稳定的密封性能、极好的耐热耐低温性能、适宜的耐酸碱性能、极佳的耐老化性能、无毒无污染性、反复利用性等优点。 The invention has stable sealing properties, excellent heat resistance, low temperature performance, a suitable acid and alkali resistance, excellent aging resistance, non-toxic and non-polluting, repeated use of the advantages. [0003] 发明内容本发明的特征在于,所述的专用三角烧瓶新型硅胶塞由瓶塞主体和砂芯片组成,可全方位地封闭三角烧瓶的瓶口。 [0003] The present invention is characterized in that said dedicated Erlenmeyer flask stopper body by the new plug of silica sand and chips, may be full-closed bottle mouth Erlenmeyer flask.
