- Laboratory funnels, adapted into different forms to suit numerous specialized needs, including filtration, are ubiquitous in the lab.
- Funnels and filtration methods are available made from plastic, glass, metal or porcelain to fit any laboratory needs. Plastic funnels that do not come into contact with solvents are generally used for transferring powders, while polyethylene funnels are used for aqueous solution transfers. Glass funnels are noted for their inertness compared to metal and plastic, while metal funnels won't chip, break or corrode.
- Glass reusable funnels are suitable for most uses that involve chemicals.
