Description
Plug for Drosophila cultivation tubes is a polyurethane foam stopper with Ø 50 mm diameter, designed to close larger fly culture tubes used in Drosophila rearing. The foam (PU) matrix permits air exchange necessary for healthy cultures while helping retain adults and protect medium from unwanted ingress. A pack of 100 unit(s) supplies busy insectaries, screening projects and teaching laboratories that process many vials per week. The 50 mm format suits wide-neck cultivation tubes where a broader plug face is required for a reliable seal. Casual reference to manufacturer Carl ROTH places the item within established labware lines for microbiology, molecular biology and cell-culture support. Uniform foam density and cut diameter promote consistent insertion force and repeatable handling during flipping, scoring and stock maintenance. These plugs complement culture-vial workflows by offering a simple, lightweight closure option that is easy to stock and replace. Specifying both material and diameter in ordering documentation reduces mismatch with tube inventories already in use.
This article is part of Test tubes, in Tubes & vials.

Questions about Plug for Drosophila cultivation tubes, Foam (PU), Ø 50 mm, 100 unit(s)
What is this article?
Plug for Drosophila cultivation tubes, Foam (PU), Ø 50 mm, 100 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Test tubes, inside Tubes & vials, in Labware.
A test tube is the open cylindrical vessel for a small liquid, in borosilicate glass or in plastic. Rimmed and rimless mouths differ. The size is diameter by length. It is not graduated for a result, and a glass tube that will be centrifuged has a force limit.
A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
