Frequently Asked Questions

AI
Glass, specifically borosilicate, is ideal for high-temperature applications and strong solvents. Polypropylene is better for acids, alkalis, and environments where breakage is a significant risk.
Fluted funnels have grooves that allow air to escape as liquid enters the receiving vessel, which prevents the 'glugging' effect and speeds up the transfer process.
Look for 'powder funnels' which typically feature a wider stem or a different angle to prevent clogging, as standard liquid funnels can easily jam when used with dry particulates.
