Here are some common uses for funnels with long stems and smooth walls made of polypropylene:
- Chemical Transfers:
- Long stem funnels are often used for transferring chemicals or reagents from one container to another. The smooth walls allow for easy and controlled pouring without the risk of spills.
- Sample Handling:
- These funnels are suitable for handling liquid samples, particularly when precision is required. The long stem facilitates the controlled transfer of small volumes of liquids.
- Solvent Filtration:
- Long stem funnels can be used in filtration processes, where a solvent needs to be filtered through a filter paper or membrane. The smooth walls ensure a smooth flow of the liquid during the filtration process.
- Chemical Additions:
- In chemical reactions, the long stem of the funnel allows for the controlled addition of reagents to reaction vessels. This is important in maintaining reaction conditions and avoiding unwanted splashing.
- Powder Transfer:
- These funnels are suitable for transferring powders or granular materials into containers. The smooth walls facilitate the flow of powders without clogging.
- Laboratory Procedures:
- Long stem funnels are commonly used in laboratories for various routine tasks, including decanting, sample preparation, and general liquid handling.
- Industrial Processes:
- In industrial settings, these funnels may be used for various applications such as the controlled addition of chemicals, transferring liquids between containers, or facilitating production processes.
- Educational Laboratories:
- Long stem funnels are often used in educational laboratories to teach students about basic laboratory techniques and procedures, providing a practical tool for students to learn about precise liquid handling.
- Quality Control:
- These funnels can be employed in quality control processes where precise and controlled additions or transfers are required to ensure the accuracy and consistency of products.
- Biological Sample Handling:
- In biological laboratories, long stem funnels with smooth walls may be used for handling sensitive biological samples or liquids in a controlled manner.
