Product Overview
Whatman CYL PC CLEAR membrane filters are engineered for high-performance filtration in demanding laboratory environments. Constructed from pure polycarbonate, these filters deliver exceptional clarity, allowing for precise microscopic examination of retained particles. The uniform pore structure ensures consistent retention efficiency, making them ideal for applications requiring reliable particle separation. Their inherent chemical resistance enables compatibility with a broad range of solvents, including alcohols, acids, and alkalis, without compromising structural integrity. The filters exhibit low protein binding, minimizing sample loss during biological filtrations, while their hydrophobic nature can be adjusted for specific applications. Each 47mm diameter disc features a smooth, non-fibrous surface that prevents particle shedding, ensuring contamination-free results. The 1.0µm pore size provides optimal balance between flow rate and retention efficiency for general-purpose filtration tasks. These filters are manufactured under stringent quality controls to meet international laboratory standards, offering researchers a dependable solution for critical filtration processes where precision and reproducibility are paramount.
FAQs
1. What is the maximum operating temperature for these polycarbonate membrane filters?
These filters can withstand continuous operation at temperatures up to 140°C, with brief exposure possible at higher temperatures depending on the specific application conditions.
2. How does the clarity of these filters compare to cellulose-based alternatives?
The polycarbonate material provides significantly higher optical clarity than cellulose membranes, allowing for better visualization of retained particles under microscopy without requiring staining procedures.
3. Can these filters be autoclaved for sterilization?
Yes, these polycarbonate filters are autoclavable at standard sterilization temperatures (121°C) without affecting their filtration performance or structural integrity.
4. What type of housing is recommended for these 47mm filters?
Standard 47mm filter holders with appropriate gasket materials are recommended, ensuring a proper seal without damaging the delicate membrane surface during filtration processes.
5. Are these filters compatible with DNA/RNA extraction protocols?
While primarily designed for particle filtration, these filters can be used in nucleic acid protocols with proper pre-treatment, though specialized nucleic acid binding membranes may offer better performance for dedicated extraction applications.
