Jan 01, 2015 · A terylene filter cloth without modification and with a pore size around 22 nm had been used in the filtration test as a filter membrane. Two pieces of membrane sheets (6 × 18 × 2 cm; total area, 0.022 m 2 ) were supported on a plastic spacer.
By virtue of structural features such as extremely small diameter, small pore size, and high porosity, PMIA nanofiber/net membranes showed superlight weight (0.365 g/m 2) with ultrathin thickness (∼0.5 μm) and robust mechanical property (72.8 MPa), which made them promising candidates for high-performance air filtration against 300–500 nm

Another 100 mm diameter×1000 mm length prototype hollow fiber module (using similar dope as mentioned refer Example-11 above) was operated for about 250 hours at high turbidity conditions up to 700 NTU. Higher dimension fiber membrane surface area was 3.5 m 2 (37.6 ft 2). A performance summary is given in table-VII

Syringe Filter, PVDF, 0.22µm, 13mm Diameter. Denville. the membrane, not leak around it. Denville Syringe Filters are easy to use. They may be used with any luer-lock syringe and are color-coded for easy recognition. The 30mm syringe filters can filter up to 100mL of sample with a retention volume of less than 100µL.
Therefore, emitting wavelengths 4300 nm and providing homogeneous surface modification of established commercial membranes illumination of up to 100 cm2 area with an intensity of made of, e.g., polyethersulfone (PES) or polysulfone, while 3575 mW/cm2, was used.
