[0002] Test tubes are commonly used instruments in chemical laboratories. They are used as reaction containers for small amounts of reagents and are used at room temperature or when heated (they should be preheated before heating, otherwise the test tubes are prone to bursting). Test tubes are divided into ordinary test tubes, support test tubes, centrifugal test tubes, etc.

[0003] The Chinese patent authorization announcement number CN 215089520 U, the authorization announcement date December 10, 2021, provides a test tube cleaning device, including multiple brush rods parallel to each other and distributed in a circular array, a screw rod arranged in the center of the multiple brush rods and parallel to the brush rods, a driving device for driving the multiple brush rods to rotate with the screw rod as the central axis, and an adjusting device for driving the multiple brush rods to move closer / away from each other; a brush rod surface is provided with bristles.
