Abstract
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.
