In lab we have Struers Tegrapol-21 grinding and polishing machine. I use it for sample preparation. Usually I put 6 samples at once and prepare them with sample holder. However today I need to prepare 3 samples. I checked brochure and it's not clear. Manual wasn't helping either.
I'm trying to understand why do I use two different type of holders. Ease of loading is an issue however I'm looking to learn is there a difference in grinding/polishing performance. Why and when I should choose one over the other?
Here is photo of single holder (left), sample holder(right) and Tegrapol-21.
- Can I use sample holder for 3 samples?
- Can I use single holder for 3 samples?
- If both of them is possible which one is preferred?
