Test Tube For Easy Enumeration And Cultivation Of Anaerobic And Facultatively Anaerobic Microorganisms
US Patent:

Filed:
Feb 7, 1977
Appl. No.:
5/766220

Abstract:
A test tube having an inner tube that allows one to insert a bar to create a dark background is described. This system is actually an ordinary or screw-capped test tube with a smaller sized test tube inverted and fused to the bottom. The design permits a thin layer of any agar medium to solidify around the inside edge of the larger tube. The colonies developed in the agar can then be easily counted by creating a dark background by inserting a dark colored rod through the opening of the inner tube.
Alternatively, a permanently dark-colored inner tube can be inverted and fused to the bottom of the outer tube. In this case, it is not necessary to insert a rod to create a dark background and the enumeration of microbial colonies is as easy as the method described above.
