To properly conduct your tests with liquid or powder witnesses, compounds (soils, leaves), organic materials, etc., or witness words, saliva-impregnated cotton, blood witnesses, we offer blown glass test tubes that seal hermetically with a cap.

You can thus create sets of permanent witnesses, identified by a label on the glass tube.
-
If you reuse a test tube, clean it with soapy water and pass a small piece of sulfur mounted on a thin rod (or pencil) inside the tube.
