How to Choose the Best Lab Funnels
Material Matters
Lab funnels come in several materials, each suited for different applications. Glass funnels are common due to their chemical resistance and ease of cleaning, making them ideal for general laboratory use. However, they are fragile. Plastic funnels, often made from polypropylene or polyethylene, are more durable and less expensive, suitable for non-critical applications or when breakage is a concern. For filtering, Büchner and Hirsch funnels, typically made of porcelain or plastic, are designed with perforated plates to support filter paper.
Size and Shape Considerations
The size of a funnel is determined by its stem diameter, top diameter, and overall height. Smaller funnels are suitable for precise pouring into narrow openings, while larger funnels are better for bulk transfers. The shape also plays a role:
- Conical (or funnel) funnels: The most common type, with a wide opening and a long, tapered stem, ideal for general pouring and filtration with filter paper.
- Separatory funnels: Feature a stopcock at the bottom of the stem, allowing for controlled separation of immiscible liquids.
- Buchner and Hirsch funnels: Designed for vacuum filtration, with a perforated plate instead of a solid cone.
Specialized Features
Beyond basic design, consider specialized features. Some funnels have ground glass joints for secure connections to other lab glassware. Graduated funnels offer volume markings for more precise measurements during transfer. For applications involving volatile or hazardous substances, funnels with lids or stoppers can minimize evaporation and prevent spills.
