Abstract:
The invention is a combination of a Durham tube and traditional chemistry test tube, with the Durham tube affixed upside down in the interior of a test tube. The Durham tube is secured so it does not move around, by constructing the test tube and Durham tube in one piece, or using a clip to keep it from moving.
