Disposable digestion tubes, also called DigiTUBEs, are made of virgin polypropylene specifically designed for use in the DigiPREP or other graphite block digestion systems. These tubes come with or without a screw cap and can also be used in combination with a polypropylene watch ‘glass’.

Particles that remain after digestion must be filtered out of the solution before the solution is analysed with the AAS, ICP-OES or ICP-MS. This can be done with disposable DigiFILTERs.
