Abstract

A device for testing a sample solution comprising a test chamber comprising a test component enclosed with air impermeable casing, a sample inlet distal from the test component capable of being connected to a sample solution and, in a test position, maintaining at higher altitude than the liquid level within the test chamber, a sealable air vent distal from the sample inlet capable of permitting air to exit the test chamber when a sample solution flows into the test chamber through the sample inlet and being closed by a sealing means and stopping sample inflow through the sample inlet when sufficient sample solution flows into the test chamber and before the liquid level within the test chamber reaches the level of the sample inlet. The device is useful for testing a portion of a sample solution without contaminating the remaining portion of the sample solution.
