BrightStar Polycarbonate Track Etched (PCTE) membrane filters are precision manufactured for applications requiring uniform pore and high particle retention accuracy. These membranes feature a disk diameter of 47 mm with a defined pore of 10 µm, providing consistent flow rates and reliable filtration results. Made from durable polycarbonate material, the track etched structure ensures straight cylindrical pores for accurate particle capture and microscopic analysis. Ideal for laboratory filtration, particle analysis, environmental monitoring, and cell biology applications. Supplied as a convenient pack of 100 membranes, these filters are designed for compatibility with standard 47 mm filter holders and laboratory filtration systems.
