ABSTRACT:
A small volume laboratory filter having a thin rectangular body and coaxial inlet and outlet sleeves connected to opposite ends thereof. A very thin filter cavity is formed in the body and lies in a plane inclined slightly to the common axis of the inlet and outlet sleeves. The cavity is divided by a filter membrane into extremely thin chambers, one communicating with the inlet sleeve and the other with the outlet sleeve. A rigid package for the filter is sealed across one end by a flexible cover which when stripped from the package exposes the inlet sleeve so that it may be readily engaged by a syringe nipple or other fluid source without the user having to touch the filter. When the inlet sleeve is engaged, the filter may be withdrawn from the package.
