2023 G-Probe test material availability
We are expecting to dispatch the test materials for the 2023 G-Probe Rounds 27 and 28 in late March/ early April.
The test materials will be a basanite glass (Round 27) and a nanoparticulate powder pellet of a fossil coral (Round 28).
Both the G-Probe 26a report for the basalt glass, KBa-1G,
and the G-Probe 26b report for the basalt nano-pellet KBa-1NP,
the test materials for 2022, are available for download.
