I am planning to switch from Alumina to SiC tubular ceramic membrane for my system and am interested to find out whether you have 19/6 or 19/8 1200mm L of 0.04-0.05micron pore size SiC membrane. Each project will require about 260 to 520 pieces. Please confirm. If do not have, what other sizes do you have.? Andrew Liew +60128667711 Show More
