Frequently Asked Questions — Carrier Free
What does Carrier Free mean?
Carrier Free indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.
Is Carrier Free the same as analytical or reagent grade?
No. Analytical and reagent grades are designed for laboratory measurement; industrial / specialty grades are designed for end-use performance. The specifications are tuned to the application rather than to general analytical chemistry.
What kind of documentation is provided?
Each lot ships with a Certificate of Analysis listing tested specifications relevant to the application. SDS, regulatory documentation and lot-specific data are available on request.
Can I order custom specifications or bulk quantities?
Yes. Bulk drums, lined packaging, custom specifications and recurring supply contracts are available through the Bulk & Custom Quote workflow. Custom specification work typically requires a technical conversation up front.
What pack sizes are available?
Industrial grades are typically offered in larger format — 1 kg, 5 kg, 25 kg drums, and larger upon request. Smaller R&D quantities are usually available; check the product page for current stock.
