About IsotopeSDS
IsotopeSDS is an independent index of supplier-published isotope and chemical safety data sheets. It is not the document manufacturer or a certification service.
What this library contains
434 active product records and 1141 retained PDF files, including supplier filename aliases and records held for mismatch review. The current catalog uses Neonest AB / BuyIsotope source documents in English.
How to choose a document
- Match the chemical, isotope, physical form and supplier.
- Read the scope and any mismatch notes.
- Check the revision date in the original PDF with the supplier.
- Confirm enrichment and batch applicability; these are not established by most element-family SDS files.
PDF and Word provenance
Original PDFs are stored unchanged with a SHA-256 checksum. Word downloads are page-image conversions of those PDFs. They preserve diagrams and page layout but are not editable-text or supplier-issued Word originals. Extracted web text is provided for search and accessibility; the source PDF governs.
Review policy
Source discrepancies are clearly marked and excluded from active search results and indexing. Automated source checks record changes for review; they do not silently replace published safety documents.
