The integrated PTFE frit provides a uniform pore structure, enabling efficient particle retention while maintaining high flow rates. This design minimizes sample loss and ensures consistent filtration performance, even under demanding conditions. The holder?s robust construction and leak-proof design make it ideal for applications requiring high purity and accuracy. Whether used in routine lab procedures or specialized research, this glass holder delivers durability and consistent results. Its compatibility with standard filtration setups enhances versatility, while the PTFE frit?s inert nature prevents contamination, ensuring the integrity of your samples.
FAQs
1. What is the material composition of the PTFE frit in this glass holder?
The PTFE frit is made from polytetrafluoroethylene, a chemically inert and hydrophobic material known for its resistance to most solvents and acids.
2. Can this holder be autoclaved for sterilization?
Yes, the borosilicate glass construction allows for autoclaving, making it suitable for applications requiring sterile conditions.
3. What is the maximum pressure this holder can withstand during filtration?
The holder is designed to handle moderate vacuum pressures typically used in laboratory filtration, though exact limits depend on the specific setup and seals used.
4. Is this holder compatible with organic solvents?
Yes, the PTFE frit and borosilicate glass are both highly resistant to organic solvents, ensuring reliable performance in such applications.
5. How do I clean the glass holder after use?
Rinse thoroughly with a compatible solvent followed by distilled water, then dry or autoclave if sterilization is required. Avoid abrasive cleaners to preserve the frit?s integrity.
