 布氏漏斗及其抽滤装置

一、产品简介

(南京——瑞尼克)(138--138--64400)聚四氟乙烯布氏漏斗[1]及其抽滤装置,简称聚四氟乙烯抽滤瓶,抽滤装置。是实验室中使用的一种仪器,用来使用真空或负压力抽吸进行过滤。普遍认为发明者为1907年诺贝尔化学奖获得者爱德华·比希纳,事实上布氏漏斗是由化学家Ernst Büchner发明的。在现代实验室中,逐渐取代陶瓷布氏漏斗及其配套的玻璃抽滤瓶。

布氏漏斗形状为扁圆筒状,圆筒底面上开了很多小孔,下连一个狭长的筒状出口,详细可参照图片。

二、使用事项 

使用的时候,一般先在圆筒底面垫上滤纸,将漏斗插进布氏烧瓶上方开口并将接口密封(例如用橡胶环)。布氏抽滤瓶(一般建议用聚四氟乙烯材质)的侧口连抽气系统。然后将欲分离的固体、液体混合物倒进上方,液体成分在负压力作用下被抽进抽滤瓶中,固体留在上方。 聚四氟乙烯抽滤瓶,有一定的厚度,可以耐受一定的负压,抽滤时,不会变形、损坏。是现代实验室抽滤的最佳选择。

常用于有机化学实验中提取结晶,这种情况的过滤完成后,还可以在上方用少量纯溶剂来洗掉结晶表面的杂质。

三、布氏漏斗的使用 

先用水把滤纸润湿,抽一下,使滤纸紧靠在漏斗底端,可以防止待过滤的东西漏掉。倒入滤液,开机器抽,可以稍微搅拌,只剩下滤出物质(可见高中化学《实验化学》)

直接用普通的漏斗,贴上滤纸后,接上抽气泵进行吸滤(替代聚四氟乙烯布氏漏斗)是不行的。因为漏斗四壁紧贴滤纸处,负压吸滤对其不起作用。只有漏斗下顶角处产生压强差。由于该口较大,且只有一个口,很容易破裂(使滤纸不牢,影响抽滤结果)

四、布氏漏斗的特点 

可代替市场上的陶瓷布氏漏斗,避免碎裂

1.耐腐蚀性强:可耐受强酸强碱、王水、魔酸、氢氟酸等各种有机试剂

2.外观纯白色,耐高温:使用温度-200到+250度

3.防污染:金属元素空白值低,铅、铀含量小于0.01ppb

4.表面不沾,易于清洗

5.使用真空或负压力抽吸进行过滤也可与吸滤瓶配套,用于无机制备中晶体或粗粒沉淀的减压过滤,可防止腐蚀性溶剂溅出

五、抽滤装置 

简单的说就是一个定制的抽滤瓶,配套布氏漏斗,侧部连接抽气系统,使用安装简单,使用方便,且整个装置都采用聚四氟乙烯材料加工制作,不会出现破裂的状况,使用寿命长,可以耐受强酸强碱、王水、氢氟酸等一切有机溶剂。

整个聚四氟乙烯抽滤装置都采用聚四氟乙烯材料加工,表面不沾,实验结束后,清洗方便。

备注:可以根据客户要求定制各种规格的布氏漏斗以及配套的抽滤装置。 

六、抽滤瓶应用 

聚四氟乙烯抽滤瓶及其整个抽滤装置,现在越来越多的被广大用户选用,是现在抽滤实验中必不可少的最佳工具之一,被广泛用于化学实验中。
