ABSTRACT:
A biological testing device comprising a container and plug is disclosed. The container in combination with the plug makes it possible to test a bacterial suspension with a number of different reagents simultaneously. The container which is open at one end has a plurality of microtubes arranged around its lower inside periphery. The plug which fits within the opening of the container distributes the bacterial suspension in substantially equal amounts to each of the microtubes having different testing reagents. A compression compensator adapted for use with the biological testing device is also disclosed. The compensator comprises a chamber which is in communication with the interior of the container when the plug is in place therein. The chamber contains a disc therein which can move in the manner of a piston to increase the volume of the chamber and thereby receive any gas or vapor vented from the testing device during use.
