FAQs
1. What is the difference between a syringe filter and a membrane filter?
Syringe filters are small, disposable units used for small-volume filtration directly attached to a syringe. Membrane filters are larger and can be used with various filtration apparatuses for larger volumes.
2. How do I choose the correct pore size for my filtration needs?
The pore size should be selected based on the size of the particles you want to remove. Smaller pore sizes remove smaller particles but reduce flow rate.
3. What are the common membrane materials used in laboratory filtration?
Common membrane materials include Nylon, PES, PTFE, PVDF, MCE, and Glass Fiber. Each material has unique properties and chemical compatibility.
4. Are all laboratory filters sterile?
No, filters are available in both sterile and non-sterile options. Sterile filters are essential for applications requiring contamination prevention.
5. What types of filtration systems are available for large-volume filtration?
Large-volume filtration often utilizes vacuum filtration systems. These systems utilize a vacuum pump to accelerate the filtration process, handling larger sample volumes efficiently.
