Frequently Asked Questions
1. What is the benefit of a polypropylene filtering flask?
Polypropylene flasks, like the 2000mL Thermo Nalgene model, are shatterproof and lighter than glass, making them safer for high-volume vacuum filtration in busy lab environments.
2. How do I choose the correct seal for my filter plate?
The seal material, such as FKM (Viton) from DWK Duran, should be chosen based on its resistance to the specific solvents or chemicals being filtered to ensure a long-lasting vacuum seal.
3. What are Sartorius Capsules used for?
These are self-contained, disposable filtration units used for the sterile filtration of large volumes of liquids, typically in the biopharmaceutical or food and beverage industries.
4. Do LLG filter holders include a connector?
Yes, many LLG-filter holders feature an NS 45/40 joint with an integrated GL 14 connector, allowing for secure tubing attachment for vacuum or drainage.
