Frequently Asked Questions

AI
Glass funnels, typically made of borosilicate, offer superior chemical resistance and heat tolerance, making them ideal for harsh solvents. Plastic funnels are shatterproof and lighter, suitable for general liquid separation or kitchen use, but may degrade with strong organic chemicals.
Joint sizes ensure compatibility with other lab glassware. A 24/29 joint is standard for smaller setups, while 24/40 is used for larger volumes. Matching these sizes is critical for creating secure, leak-free connections in your experimental apparatus.
PTFE stopcocks are generally preferred for their smooth operation, chemical inertness, and ease of cleaning. Glass stopcocks can seize over time due to chemical buildup or temperature changes, requiring more maintenance and lubrication to function properly.
