Häufig gestellte Fragen
What is the purity of this product, and how is it determined?
This product is supplied at ≥95% purity, determined by SDS-PAGE. Lot-specific values are stated on the Certificate of Analysis.
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.
What does Recombinant mean?
Recombinant is a defined analytical purity tier suitable for workflows requiring a specific validated property. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Recombinant is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.
How should this product be stored?
Store at ?20 °C. Avoid repeated freeze–thaw cycles. Aliquot into single-use volumes before freezing.
How is this product shipped?
This product ships in an insulated container with ice pads. Unpack on arrival and transfer it to the storage condition stated above.
What documentation is provided?
Available product documentation, including Certificates of Analysis (COA), Safety Data Sheets (SDS), and specification sheets, is shown in the product document area. Document availability and access follow the current site policy.
