The FPC polypropylene depth filter cartridge, also known as the QMC, is an innovative product from the Whatman Nuclepore Family. Serial layers of graded density-media provide for depth loading of contaminants through the entire cartridge, rather than just on the surface. This capture area is further extended by pleating the media. In addition, the QMC filter media provides exceptionally fine retention while maintaining high flow rates at low differential pressures. The QMC provides an economical operating cost while providing a high-quality output. The QMC is very clean and will not contribute debris to the filtrate. The manufacturing process prevents contamination of the process fluid by the media itself, a condition known as media migration. Extractables are negligible because no binders, adhesives or chemical additives are used in fabrication. Because the cartridge is made entirely of polypropylene, it is chemically compatible with a wide variety of chemicals.

Recommended Flow Rates per 10″ cartridge:
1.0 micron and larger: 4 to 5 GPM (15 to 19 LPM) at 72 F (22 C)
0.1 micron to 0.6 micron: 3 to 4 GPM (11 to 15 LPM) at 72 F (22 C)

Maximum Operating Pressure: 100 psid (7 Bar) at 68 F (20 C) in forward direction (outside to inside)

Maximum Operating Temperature: 176 F (80 C).
At elevated temperatures the maximum pressure drop must be reduced. At 176 F (80 C), the maximum pressure drop is 5 psi (0.34 Bar).

Sanitizing
Hot water at 176 F (80 C) at 5 psid for 30 min.
Inline steam at 257 F (125 C) at 1 psid for 30 min.
Autoclavable at 257 F (125 C) for 30 min.
