Erbium –  high precision density-standard cube 10x10x10mm NEW!
Hand Made in Austria – Shiny & oxide free surface

There are a lot of cheap counterfeits in the web where you can get metal cubes for a few Euros but you choose whether you get just a piece of metal in cube form or a density standard for scientifical or educational use. Therefore we offer 3 versions:

• Standard (cheaper but uncalibrated to weight or size +- 0.15mm) or
• calibrated to weight (+- 0.05g + printed certificate )
• calibrated to size (+- 0.05mm + printed certificate).

Select the version you need. Please note that calibration to weight means, that the cube can be up to 0.15mm bigger, because theoretical density is technically not achievable.
