Frequently Asked Questions

AI
Borosilicate glass is preferred for its high thermal resistance and compatibility with most organic solvents. Polypropylene is a better choice for applications involving hydrofluoric acid or where break-resistance is a priority.
PTFE (Teflon) stopcocks are highly resistant to chemical corrosion and do not require grease for a tight seal, reducing the risk of sample contamination.
Check that the stopcock is properly seated and the screw cap or ground-glass joint is tight. For glass funnels, ensure the joint is clean and free of debris before assembly.
