Design files, bill of materials and validation data for a frugal APCVD reactor for MWCNT synthesis

This Zenodo record archives the open-hardware documentation and validation dataset for a benchtop atmospheric-pressure CVD (APCVD) tubular reactor operated with Ar/C₂H₂. The package includes a tagged process flow diagram (Figure_1.png), a designator-based bill of materials with as-built and replication cost scenarios (bom_v1.xlsx; bom_designators_v1.pdf), operating SOPs (sops_v1.pdf), and the gravimetric run log supporting the repeatability results (runlog_gravimetry_v1.xlsx), together with citation and licensing metadata (README.md, CITATION.cff, LICENSES_README.md, CC-BY-4.0.txt).
