Appl. No.:

10/837768

International Classification:

B05D005/00

US Classification:

427209, 427211, 2641761, 2641771, 15624411

Abstract:

The present invention relates to a filter element having a non-porous extrusion laminated strip formed on at least one edge and at least one side of a membrane. The strip is used to provide a means for ensuring a good bond between the filter element and the material into which it is potted. The strip is formed by the use of one or more extrusion heads that apply molten or softened polymer to one or both of the surfaces of the filter in a width and height desired. The strip is then subjected to pressure such as through a nip to at least partially embed the polymer strip into the filter pores so as to create a strong mechanical bond between the strip and the filter element. Additionally, it allows for the simultaneous formation of more than one membrane with the edge lamination at the same time.

US Classification:

604411, 604905, 604533, 604 33, 2511499, 137614

Abstract:

A sterile to sterile connection device comprising a connector and one or more coupling devices. The connector has body portion which has two openings sealed from the environment so as to form a sterile environment within the connector. At least one of the openings being sealed from the environment by a sterile barrier plug. The connector also has a port capable movement within the body of the connector to at least an open and a closed position. The coupling device is formed of a body having two openings and a stem having a bore through at least a portion of the stem. The stem is contained within the body and capable of moving at least linearly through the body between a first and second stem position. One of the openings of the stem is sealed from the environment by a sterile barrier plug and the other is sealed to a presterilized component. The coupling device opening containing the sterile barrier plug is attached to either the inlet or outlet of the connector.

Assignee:

Millipore Corporation - Bedford MA

International Classification:

G01N 2702

US Classification:

324 711

Abstract:

A new method and apparatus is described for conducting an integrity test on porous membranes and membrane filters and for conducting a pore-size characterization of membrane. The method and apparatus apply to membrane integrity tests and pore-size characterizations which are based on the dependence on the pore size of the pressure required to intrude a non-wetting, electrically conductive liquid into and through the pores. Electrical-measurement methods are described for identifying the pressure at which intrusion occurs.

International Classification:

B01D 2706

US Classification:

210767

Abstract:

A filter cartridge is provided which includes (a) a wound depth filter or a cylindrical seamless depth filter and (b) a pleated filter having a lower micron retention rating than the depth filter. The depth filter and pleated filter surround a central opening. The cartridge is sealed and an appropriate inlet or outlet is provided in order to assure sequential fluid flow first through the depth filter and then through the pleated filter.
