Slant Test Tube Rack

The Slant Test Tube Rack has two degrees of slant for a pair of uses. One side has a five-degree slant which produces a large surface area ideal for aerobic cultures. The other side has a 20-degree slant which creates a smaller surface area. It is intended for anaerobic cultures and reduces the drying out of the test medium during storage. Medium-filled tubes are autoclaved in the upright position and then tilted to the desired angle while still hot. The rack can be submersed in a water bath or used for incubating tissue cultures. The rack comes in a 13mm to 16mm test tube size or a 16mm to 20mm tube size. Each rack has 40 places (4 x 10), which are numbered and lettered for added convenience. Measures 10-1/2 x 6 x 5-1/8" (267 x 152 x 130cm).
