A device made of non-contaminating inert material for taking and preserving a fluid sample containing volatile substances for analysis having a tubular body with gas tight valves at opposite end portions which are opened to allow fluid to pass into and out of a chamber and closed to seal off the escape of and preserve a fluid sample therein during transfer to a laboratory for analysis. Opposite end portions of the tubular body are adapted for attachment of a lower one-way inlet check valve unit and an upper outlet extension unit thereto used with a supporting line or rod to lower and raise the device into and out of a body of fluid and thereby take a fluid sample thereof for analysis. Closing of the valves traps fluid and seals off the sample taken into the chamber between the valves and is removed therefrom by piercing a septum located adjacent the chamber and between the valves by suitable means including a hypodermic needle.

This invention pertains to a tamper-proof sealing cap for a syringe. The cap is made of a partially rubber-like flexible material so that it may be partially deformed from its preselected shape. At least one of its members is preformed into a shape which prevents the re-insertion of the syringe after it has been removed.

A universal sampling device for retrieving samples of high and low viscosity substances at various depths and from specific portions of contained bodies of materials without being completely submerged therein, is disclosed. The sampling device is made of chemically inert material, has manually operable inlet and outlet vent valve means attached to opposite inlet and outlet ends of a relatively long tube into which the sample enters upon opening of the inlet and outlet valve means at the desired point in the substance to be tested. Means are provided for manually closing and opening of the inlet valve means such as pushing and pulling a valve stem by hand into sealingly engagement with an inlet valve body. Another method attaches a valve stem to an adjustable valve control rod extending upwardly through the tube and outlet valve means. Closing of the inlet valve means can be attained by pushing the device and valve stem against a bottom or side wall containing the substance until the inlet valve stem snaps closed prior to withdrawal of the device and sample therein.
