FAQ, See What Others Asked

When should I use a porcelain versus a glass separatory funnel?

Is this funnel suitable for use with aggressive chemicals?
Yes, borosilicate glass is highly resistant to acids, bases, and organic solvents, making this funnel suitable for a wide range of chemical separations in professional labs.
How long will this separatory funnel last with regular use?
With proper handling, including avoiding thermal shocks and impacts, this borosilicate funnel can last several years, providing consistent performance in demanding lab environments.
