How To Prevent Test Tubes Break When Placed In A Test Tube Rack?
(1)Hold the test tube securely by the base or neck, and gently place it in the rack. Avoid tapping or jostling the tube against the rack, as this can cause it to break.
(2)Make sure the test tube is the right size for the rack. If a tube is too small, it may wobble and break. If it is too large, it may get stuck in the rack and break when you try to remove it.
(3)Use a test tube rack with rubber grips or inserts. These can help cushion the test tube and prevent it from slipping or breaking.
(4)If the test tube rack does not have rubber grips or inserts, you can add a layer of padding by placing a folded paper towel or piece of foam beneath the tubes.
(5)When removing test tubes from the rack, grasp them firmly and lift them straight up, rather than twisting or pulling them out at an angle. This will help prevent them from getting stuck or breaking.
