Method of manufacture of hollow fiber filter cartridge with porous ring
First Claim
1. A method of sealingly coupling an annular porous collar to a casing for encasing a bundle of hollow fibers comprising:
- (a) providing an annular porous collar having a first and second outer peripheral edges, said annular porous collar including pores having a pore size distribution from about 5 μ
mm to 500 μ
m;
(b) providing a casing having first and second longitudinal ends, said casing defining a central chamber, said chamber having first and second ends wherein said longitudinal ends of said casing each include an inner, lateral, annular lip proximal to each of said ends; and
(c) coupling said first outer peripheral edge of said annular porous collar to at least one of said inner, lateral, annular lips of said casing;
wherein said casing, said annular porous collar and a potting plug of a fluid impermeable material are sealingly joined by penetration of said fluid impermeable material through said pores of said annular porous collar.

Abstract
A method of sealingly coupling a hollow fiber bundle having first and seconds ends to a porous collar having first and second peripheral edges, at least one of which is coupled to the inner ledge of a casing for encasing said bundle of hollow fibers is disclosed. The method broadly includes providing a porous collar having first and second outer peripheral edges; providing a casing having first and second longitudinal ends, the casing defining a central chamber, the chamber having first and second open ends wherein the longitudinal ends of the casing each include an inner lip proximal to the open end; coupling the first outer peripheral edge of the porous collar to the inner lip of the casing; retaining a bundle of hollow fibers having first and second longitudinal ends within the chamber; permeating the longitudinal ends of the hollow fiber bundle with a fluid impermeable material; joining the porous collar to the fluid impermeable material by penetration of the material into the porous collar; and curing the fluid impermeable material. The method provides a fluid impermeable seal between the casing and the individual hollow fibers. The seal prevents the unfiltered fluid from coming into contact with filtrate and provides a strong bond that is impervious to dry heat and steam sterilization at temperatures ranging from 100° C. to 150° C. and pressures from 10 psi to 60 psi.
