Methacrylate rod 8 cm long and 1 cm in diameter to push the cotton out of the test tubes.
The preparation of test tubes for queens or colonies is a simple process. Simply fill the test tube two-thirds full with water and insert a cotton ball that comes into contact with the water to keep it moist and provide a source of water and moisture for the queens or colonies.
It is important that both our hands and the instrument with which the cotton is pushed are clean so as not to contaminate either the water or the cotton. This rod will allow you to push the cotton when preparing the test tubes with the greatest guarantees of cleanliness as many times as you need, since it can be washed easily.
