Test Tube Holder
A test tube holder is useful for holding a test tube which is too hot to handle.

Test Tube BrushesTest tube brushes are used to clean test tubes and graduated cylinders.
Forcing a large brush into a small test tube will often break the tube.

Test Tube Racks
Test tube racks are for holding and organizing test tubes on the laboratory counter. Plastic racks may melt in contact with very hot test tubes.

Rubber StoppersRubber stoppers are used to close containers to avoid spillage or contamination.
Containers should never be heated when there is a stopper in place.
