Astimex standard mount MINM25-53

Standards

The Microprobe Lab has an extensive set of analytical standards, both from commercial sources and developed in house.

Commercial standards

The lab has three broad-application standard mounts fabricated by Astimex Scientific Limited. Links provide details on the contents of each standard.
