PFA (perfluoroalkoxy) and glass separatory funnels are both commonly used in laboratory settings for separating and transferring liquid mixtures. while they share some similarities in terms of function, there are several key differences between the two.

 

One significant difference is their material composition. PFA is a type of fluoropolymer that is highly resistant to chemicals and heat, making it ideal for use with corrosive liquids and in high-temperature applications. Glass, on the other hand, is a more traditional material that is also chemically inert but may not be as suitable for high-temperature use.

 

Another key difference is the transparency of the materials. PFA is typically translucent or opaque, which can make it difficult to see the contents of the funnel during the separation process. Glass, on the other hand, is transparent, allowing for easy visualization of the liquids being separated.

 

Additionally, PFA funnels are often considered to be more durable than glass funnels, as they are less likely to break or shatter if dropped or exposed to sudden temperature changes.
