Application Sample Preparation
Hydrophobic, polytetrafluoroethene (PTFE) membranes are recommended for use with non-aqueous solvents. Organic-based, highly acidic or basic samples and solvents
Reliable Filtration PerformanceThis syringe filter offers consistent and precise filtration with its 0.45 m pore size. The PTFE membrane ensures high chemical compatibility and efficient removal of particulates from aggressive solvents, acids, and bases, vital for accurate analytical results.
Versatile Applications in Analytical LaboratoriesIdeal for HPLC, GC, and other analytical methods, the filter is suitable for the preparation of various sample types. Its hydrophobic properties make it particularly effective in both aqueous and non-aqueous solution processing, supporting demanding research workflows.
Robust Chemical ResistanceConstructed using high-grade PTFE and polypropylene, the Acrodisc PTFE CR filter resists chemical degradation and minimizes extractables. This promotes sample purity and filter longevity, ensuring reliable results even with strong solvents and harsh chemicals.
FAQ's of Waters Corp PTFE CR Acrodisc Syringe Filter, 4 mm, 0.45 Am, 250/case:
Q: How is the Waters Acrodisc PTFE CR Syringe Filter used in laboratory workflows?
A: The filter is used for manual filtration of laboratory samples to remove particulates before analysis, especially for HPLC, GC, and other techniques that require particle-free solutions. Simply attach the filter to a compatible syringe, draw up your sample, and then push the sample through the filter into a collection vessel.
Q: What types of chemicals and solutions is this syringe filter compatible with?
A: The PTFE membrane and polypropylene housing provide exceptional compatibility with organic solvents, strong acids, strong bases, and both aqueous and non-aqueous solutions. This makes it suitable for use in a wide variety of analytical, research, and industrial laboratory applications.
Q: When should I select a 0.45 m pore size for filtration?
A: A 0.45 m pore size is recommended when you need to remove fine particulates from your samples before HPLC, GC, or other analytical techniques. It is especially useful for preparing samples that might clog sensitive instruments or interfere with accurate measurements.
Q: Where can this syringe filter be utilized most effectively?
A: The Acrodisc PTFE CR Syringe Filter is best used in research, quality control, and analytical laboratories that handle aggressive solvents, chemicals, and a variety of sample types. It is widely utilized in fields such as pharmaceuticals, environmental science, and chemical analysis.
Q: What is the filtration process for this product?
A: The filtration process involves attaching the filter to a syringe, drawing the sample into the syringe, and then pushing it through the filter. The PTFE membrane retains particulates larger than 0.45 m while allowing the desired solution to pass through, providing a clean sample for analysis.
Q: What are the benefits of using a PTFE hydrophobic membrane filter?
A: PTFE hydrophobic membranes resist a broad range of chemicals, provide low extractables, and prevent sample loss due to binding. They maintain sample integrity and are especially useful for aggressive or reactive chemicals, ensuring the reliability of analytical results.
