Tube preparation rod

Methacrylate rod, 8 cm long and 1 cm in diameter, for pushing the cotton in test tubes.

Preparing test tubes for queens or colonies is a simple process. You simply need to fill two-thirds of the test tube with water and insert a cotton plug that makes contact with the water, keeping it moist and providing a source of water and humidity for the queens or colonies.

It is important that both your hands and the instrument used to push the cotton are clean, so as not to contaminate the water or the cotton. This rod allows you to push the cotton into place when preparing test tubes—ensuring maximum cleanliness—as often as needed, since it is easy to wash.
