Multi-branch Manifold Membrane Filtration System

Membrane filtration

Negative pressure generated by vacuum pump draws the liquid sample pass through membrane, filtering microbial particles smaller than the pore size on membrane, and those deposited on the membrane then will be sent for further analysis.

1: Place disinfected membrane on sterilized filter bolster. 2: Put on disinfected funnel and fill in liquid sample. 3: Start vacuum pump and adjust to -0.5 atmospheric pressure, and open corresponding valve to begin leaching. 4: After leaching (filtering), take the membrane and put it (them) on Petri dish (with medium) to incubate and for further analysis. Features and advantages: 1. Patent product: The stainless steel fixture obtains patent for its design. It is safe, simple and convenient. 2. Modular design: There is an independent switch to every funnel. You can filter the single sample or more than one sample at the same time. The filter system integrates one stop solution, it equipped with oil-free vacuum pump or diaphragm pump and operational autoclavable liquid storage bottle. This system is fit for using in the clean room and lab etc. 3. Scientific and ergonomic design: Stainless steel filter frit is made of high grade 316L stainless steel to ensure the microorganism and granule can distribute equably on the surface. It won’t fracture membrane or bore a hole during filtering. 4. Avoid second pollution: Every funnel is equipped with individual cover. The Air Filter (optional) can be mounted on the hole of the cover, which avoids second pollution during leaching. 5. Enhance detection efficacy: It is easy to clean and sterilize. You can choose moist heat (121°C or 134°C) for 15min or dry heat (180°C) for 120min, and the most effective method is flame ignition using the optional equipped sterilizer. There are clear graduations in the funnel. It is convenient to add the sample quickly and exactly. 6. Durable material: The main components (the filter, the filter fastener, valve, fixture, filter cloth et al) are made of 316L stainless steel. Specifications for the filtration system: 1.
