Tired of not being able to extract the cottons from the bottom of used test tubes?
With this hook you will be able to extract even the most embedded cottons. You just have to insert the hook, screw it into the cotton and pull carefully so as not to scratch the walls of the tube.
Perfect for extracting cottons in 16mm tubes.
Hook measurement: 18 cm
