Apparatus for measuring gas exchange
First Claim
1. A high precision low cost manometer for measuring gas exchange comprising:
- a container having a port for holding a liquid medium and a reactant that interacts with said liquid medium to produce a change in gas levels within said container;
a removable stopper for insertion into said port creating an airtight seal;
a tube extending through said stopper into said container having a distal end for being submerged in said liquid medium;
said tube adapted for receiving said liquid medium and monitoring a change in the level of said liquid medium within said container as a result of gas exchange;
a controller extending through said stopper into said container for setting said liquid medium at a level within said tube; and
,wherein said controller is operable to direct the liquid medium into said tube to a desired level so that a change in gas levels caused by the interaction of said reactant with said liquid medium can be monitored through a change in the level of the liquid medium within said tube.

Abstract
A container having a port for holding a liquid medium and a reactant that interact to produce a change in gas levels within the container. A removable stopper for insertion into the port creating an airtight seal. A tube extending through the stopper into the container having a distal end for being submerged in the liquid medium for receiving the liquid medium and monitoring a change in the level of the liquid medium within the container. A controller is provided extending through the stopper into the container for setting the liquid medium at a level within the tube, wherein the controller is operable to direct the liquid medium into the tube to a desired level so that a change in gas levels caused by the interaction of the reactant with the liquid medium can be monitored through a change in the level of the liquid medium within the tube.

16. A method for measuring gas exchange comprising the steps of:
-
providing a container having an open port for accessing said container; inserting a liquid medium into said container; inserting a reactant into said container for interacting with said liquid medium to produce a change in gas levels within said container; providing a removable stopper carrying an elongated tube and a controller for insertion into said port creating an airtight seal; inserting said stopper carrying said tube and said controller into said port so that a distal end of said tube is submerged in said liquid medium and said controller is in fluid communication with said container; and
,operating said controller to direct said liquid medium into said tube to set the liquid medium at a desired level within said tube so that a change in gas levels within said container caused by the interaction of said reactant with said liquid medium results in a change in the liquid medium level within said tube to indicate gas exchange. - View Dependent Claims (17, 18, 19, 20)

21. An apparatus for measuring gas exchange comprising:
-
a stopper for use with a container having a liquid medium and a reactant for creating gas exchange, said stopper being adapted to be removably inserted into a port of said container to create an airtight seal with said container; a tube carried by said stopper for extending into said container to receive said liquid medium and monitor a change in the level of said liquid medium within said container as a result of gas exchange when said stopper is inserted into said port; and
,a controller carried by said stopper for extending into said container to set the level of said liquid medium within said tube when said stopper is inserted into said port, and allowing for the level of said liquid medium within said tube to be reset without exposing an interior of said container to ambient air so that a change in gas levels within said container can be monitored. - View Dependent Claims (22, 23, 24)
