DURAN® Test Tube
Test tube are used for simple esperoments, in particular for qualitative chemical analyses. These are available in a variety of sizes.
Test tube sizes are only roughly matched to a particular capacity. The exact capacity does not matter. There is, therfore, no need for any indication of capacity or calibration. The crucial factor when carrying out test tube experiments is generally the change of that occurs to the contents, e.g. any change in colour.
DURAN® test tubes are available with or without beaded rim. If the contents are frequently poured out or shaken, it is advisable to use test tubes with beaded rim.
