Tools & Calculators
Free online tools for metallographic sample preparation: grit conversions, ASTM E112 grain sizing, polishing-time and resin-volume calculators, mold compatibility checks, and etchant selection.
Calculators
3 toolsGrit Size Converter
Convert between FEPA (P-Grade), ANSI, JIS, and micron measurements. Covers P12 through P5000 plus diamond and colloidal silica final-polish sizes.
Grain Size Calculator
Calculate ASTM grain size numbers per ASTM E112. Supports intercept and planimetric methods, and converts between G and mean diameter in µm or mm.
Mounting Material Calculator
Resin volume and weight for compression or castable mounting, density-corrected for phenolic, epoxy, acrylic, polyester and conductive resins. Built-in safety margin.
Reference
2 toolsSample / Mold Compatibility Checker
Enter rectangular or cylindrical sample dimensions and see which standard imperial or metric mounting molds will fit with adequate edge-retention clearance.
Lab Builder
Build an equipment and consumable list from your sample types, throughput, and workflow. For new lab setups or capability expansions.
