Product Description
All plastic soft drink bottles start out as small PET "preforms" - or what we have labeled, crash proof test tubes for the classroom. In the factory these preforms are heated and blown into the well-known soft drink bottles we all know.
Each tube holds ±40 ml and is 14 cm tall.
They have numerous GREAT safe applications in the classroom, some of which are:
-
Collecting & storing liquids;
- Growing expanding spheres;
- Preparing a density column or wave simulator;
- Storing of sedimentation or sand layers;
- Germinating seeds using different mediums; etc.
The screw-on caps act as test tube stands too. Test tubes are supplied without caps. Order the caps separately in this shop. Simply search for the code: M39C
