| PTFE Funnel
PTFE Funnel applies to the chemical industry, petrochemical industry, biochemical, and pharmaceutical industries, and laboratories and educational institutions.
PTFE laboratory funnels are for use under the most adverse conditions. Their chemical resistance can be thought of as being nearly “total” since there are so few compounds that will attack the PTFE used in the production of these funnels. And unlike glass, there is nothing that can leach out and cause contamination, since only ultra-pure materials are passed through the funnel. And just as the “non-stick” properties of PTFE are well known when applied to a cooking utensil, similarly, nothing sticks to the very smooth walls of the PTFE funnels.
