Abstract
Abstract A fluid sampler having a cover assembly with an inlet and a transparent top and a cylinder-like bottom portion open at the upper end and closed at the lower end, except for an outlet. A suitable filter is disposed in the bottom portion over the outlet. The cover assembly and the bottom portion are removably connected and form a cavity. The fluid to be filtered is introduced into the fluid sampler through the inlet; enters the cavity; passes through the filter; and exits through the outlet. The contaminants are left on the filter and may be analyzed or counted by suitable means, such as a microscope, through the transparent top, without removal of the filter from the fluid sampler.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
167 words
A fluid sampler which permits particulate analysis while the sampler is in an assembled condition, comprising: a. a bottom portion, cylinder-like in configuration, open at the upper end and closed at the other end, except for a suitably positioned outlet, and having a cylinder-shaped recess in said other end; b. a suitable filter positioned in a flat mode in said recess of said bottom portion; c. a top portion cover assembly, including: 1. a hollow female part, torus-like in configuration, threaded at its lower end on the internal surface, and having a suitably positioned inlet; 2. a hollow male part, cylinder-like in configuration, openended, threaded at its upper end on the external surface, and in threaded connection with said female part; 3. and, a transparent disc affixed to the inner periphery of said female part, and disposed between said female part and said male part; with said bottom portion and said top portion cover assembly removably united to form a single integrated unit with a cavity therein.
Claim 2
Dependent Claim
