四氟烧瓶：聚四氟乙烯反应瓶、圆底烧瓶、三颈烧瓶等。

产品特点

1、通常有单颈、三颈和四颈，17、19、24等标准口，均配有塞子；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℃。

2、可根据您的要求定向加工四氟圆底烧瓶。

3、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。

4、蒸馏烧瓶一种用于液体蒸馏或分馏物质的四氟容器。常与冷凝管、接液管、接液器配套使用，所以一般做成3颈，也可装配气体发生器。

5、通常具有圆肚细颈的外观，与烧杯明显地不同；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。

6、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。

7、烧瓶因瓶口很窄，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。

8、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。

9、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。

安装步骤与维护

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。
