Round Bottom Tapered Neck Cups

Developed from a high fired Alumina body. Extremely porous, inert to most all solutions, possesses hard exterior and interior surfaces, and pure white in color. Recommended for standard pressure differentials under 1 Bar (14.5 psi). Typical bubbling pressure: 28 - 32 psi. Effective pore size: 2.5 microns. Hydraulic conductivity: .0000086 cm/sec. Approximate porosity: 45% by vol. Flow through. All cups are "as cast".
