Claim 7

The apparatus of claim 4 including: means to track said piston moving in said vessel; and means to display on the exterior of said vessel the moving location of said piston.

Claim 8

An integrated pump and sample vessel comprising: a body with a longitudinal bore therethrough; a passage in said body allowing fluid to enter and exit said body; a vessel for the storage of samples taken from said fluid; check valve means located in said vessel to selectively enable the entry of fluid from said passage into said vessel; an adapter for detachably mounting said vessel on said body, said adapter having a face exposed to said passage; a resilient member located in said bore having a face with a cavity therein exposed to said passage; a hollow sleeve confining said resilient member; means to break a vacuum between said face of said adapter and said face of said resilient member; and means for relatively moving said face of said resilient member in said passage toward said face of said adapter and into contact with the vacuum breaking means for trapping a sample of fluid in said cavity, said moving means resiliently collapsing said cavity which pumps sample past said check valve means and into said vessel.

Claim 9

An integrated pump and sample vessel comprising: a body with a longitudinal bore therethrough; a passage in said body allowing fluid to enter and exit said body; a vessel for the storage of samples taken from said fluid; check valve means located in said vessel to selectively enable the entry of fluid from said passage into said vessel; an adapter for detachably mounting said vessel on said body, said adapter having a face exposed to said passage; a resilient member located in said bore having a face with a cavity therein exposed to said passage; a hollow sleeve confining said resilient member; means to break a vacuum between said face of said adapter and said face of said resilient member; and means for relatively moving said face of said resilient member in said passage toward said face of said adapter and into contact with the vacuum breaking means for trapping a sample of fluid in said cavity, said moving means resiliently collapsing said cavity which pumps sample past said check valve means and into said vessel.

Claim 10

The apparatus of claim 7 including means to relieve over pressures in said vessel.

Claim 11

The apparatus of claim 8 including means to measure pressure in said vessel.

Claim 12

The apparatus of claim 7 including a piston located in said vessel which divides said vessel into two separate chambers.

Claim 13

The apparatus of claim 10 wherein, said piston has a conical protrusion therefrom which fits into a conical depression in said vessel.

Claim 14

The apparatus of claim 11 including: means to track said piston moving in said vessel; and means to display on the exterior of said vessel the moving location of said piston.

Claim 15

A sampling system comprising: a. a detachable sample vessel including; (i) an elongate tube having a first end cap and a second end cap defining a sample storage chamber; (ii) said first end cap of said tube having a cylindrical neck extending therefrom, said neck having a smaller diameter than said tube and said neck having a pocket formed therein; (iii) check valve means contained in a removable pod, said pod contoured to fit into said pocket of said first end cap, to selectively enable the entry of a fluid into said sample storage chamber; (iv) restraining means detachably mounting on said neck of said first end cap of said tube to restrain said pod in said pocket, said restraining means having a face thereon; b. a pump including; (i) a body with a longitudinal bore therethrough; (ii) a passage in said body allowing said fluid to enter and exit said body; (iii) a resilient member located in said bore having a face with a cavity therein exposed to said passage; (iv) a hollow sleeve to confine said resilient member; and (v) means for relatively moving said face of said resilient member towards said face of said restraining means for trappaing a sample of fluid in said cavity, said moving means resiliently collapsing said cavity which pumps said sample past said check valve means and into said sample storage chamber; and (c) means for detachably mounting said sample vessel on said pump to expose said face of said restraining means to said passage.

Claim 16

A sampling system comprising: a. a detachable sample vessel including; (i) an elongate tube having a first end cap and a second end cap defining a sample storage chamber; (ii) said first end cap of said tube having a cylindrical neck extending therefrom, said neck having a smaller diameter than said tube and said neck having a pocket formed therein; (iii) check valve means contained in a removable pod, said pod contoured to fit into said pocket of said first end cap, to selectively enable the entry of a fluid into said sample storage chamber; (iv) restraining means detachably mounting on said neck of said first end cap of said tube to restrain said pod in said pocket, said restraining means having a face thereon; b. a pump including; (i) a body with a longitudinal bore therethrough; (ii) a passage in said body allowing said fluid to enter and exit said body; (iii) a resilient member located in said bore having a face with a cavity therein exposed to said passage; (iv) a hollow sleeve to confine said resilient member; and (v) means for relatively moving said face of said resilient member towards said face of said restraining means for trappaing a sample of fluid in said cavity, said moving means resiliently collapsing said cavity which pumps said sample past said check valve means and into said sample storage chamber; and (c) means for detachably mounting said sample vessel on said pump to expose said face of said restraining means to said passage.
