The filter’s core strength is its capacity and purity. Its high loading capacity and smooth surface make it ideal for filtering turbid solutions and ensuring efficient precipitate recovery. With a nominal particle retention of 1.5 µm and a Fast Flow Rate, it is perfect for time-sensitive procedures. The binder-free, high-grade borosilicate glass can withstand temperatures up to 550°C and is essential for preventing contamination in sensitive analytical methods like scintillation counting and cell harvesting during incorporation trials.
Features:
- Standard filter for suspended solids (TSS) in water analysis
- Fine particle retention of 1.5 µm and Fast Flow Rate
- High loading capacity makes it ideal for processing turbid solutions
- Binder-free, high-grade borosilicate glass withstands temperatures up to 550°C
- Widely used for cell harvesting, mixed lymphocyte culture tests, and scintillation counting techniques
- Smooth surface provides efficient precipitate recovery
