Product Details
规格:
25ml~5000ml
使用温度:
250℃
材质:
高纯聚四氟乙烯
 聚四氟乙烯烧瓶、反应瓶

聚四氟乙烯(PTFE)烧瓶、反应瓶:聚四氟乙烯(PTFE)圆底烧瓶有单颈、三颈和四颈,17、19和24等标准口,每个标准口配有塞子。可拆卸清洗,内壁光滑。

 用于:水浴锅、油浴锅等加热。

 使用温度:-200℃~+250℃。

 可根据您的要求定向加工四氟圆底烧瓶。

 聚四氟乙烯烧瓶通常有平底和圆底之分。

 平底的叫做平底烧瓶,圆底的叫圆底烧瓶。

 蒸馏烧瓶一种用于液体蒸馏或分馏物质的玻璃容器。常与冷凝管、接液管、接液器配套使用。也可装配气体发生器。

 聚四氟乙烯烧瓶通常具有圆肚细颈的外观,与烧杯明显地不同。它的窄口是用来防止溶液溅出或是减少溶液的蒸发,并可配合橡皮塞的使用,来连接其它的聚四氟乙烯器材。当溶液需要长时间的反应或是加热回流时,一般都会选择使用聚四氟乙烯烧瓶作为容器。烧瓶的开口没有像烧杯般的突出缺口,倾倒溶液时更易沿外壁流下,所以通常都会用四氟搅拌棒轻触瓶口以防止溶液沿外壁流下。烧瓶因瓶口很窄,不适用四氟搅拌棒搅拌,若需要搅拌时,可以手握瓶口微转手腕即可顺利搅拌均匀。若加热回流时,则可於瓶内放入磁搅拌子,以加热搅拌器加以搅拌。烧瓶随著其外观的不同可分平底烧瓶和圆底烧瓶两种。如图所示。通常平底烧瓶用在室温下的反应,而圆底烧瓶则用在较高温的反应。这是因为圆底烧瓶的四氟材料厚薄较均匀,可承受较大的温度变化。

安全使用方法

①应放在石棉网上加热,使其受热均匀;加热时,烧瓶外壁应无水滴。

②平底烧瓶不能长时间用来加热。

③不加热时,若用平底烧瓶作反应容器,无需用铁架台固定。

主要用途

(1)液体和固体或液体间的反应器

(2)装配气体反应发生器(常温、加热)

(3)蒸馏或分馏液体(用带支管烧瓶又称蒸馏烧瓶)

使用注意事项

1.加热时要垫石棉网,也可以用其他热浴加热。加热时,液体量不超过容积的2/3,不少于容积的1/3。

2.配置附件(如温度计等)时,应选用合适的橡胶塞,特别注意检查气密性是否良好。

3.蒸馏时最好事先在瓶底加入少量沸石,以防暴沸。

4.加热时应放在石棉网上,使之均匀受热。

5.蒸馏完毕必须先关闭活塞后再停止加热,防止倒吸。

特点:

1.外观纯白色。

2.耐高低温:使用温度-200℃~+250℃。

3.耐腐蚀:耐强酸、强碱、王水、魔酸、氢氟酸和各种有机溶剂。

4.空白值低:极低的金属离子溶出和析出。

5.防污染:金属元素空白值低,铅、铀含量小于0.01PPB是目前国内外最先进的分析。

6.绝缘性:不受环境及频率的影响,介质损耗小,击穿电压高。

7.表面不粘性:是一种表面能最小的固体材料。

广泛应用在国防军工、原子能、石油、无线电、电力机械、化学工业等重要部门。
