Frequently asked questions

Our catalog is intended for qualified laboratory research. These materials are not for human or animal consumption or administration. Product descriptions provide research context, not treatment recommendations or instructions for personal use.

Mass (mg) and volume (mL) describe the listed size of a product. Quantity is the number of units added to your cart. Open a product page to see its available sizes; the size selection and quantity are separate controls.

Storage requirements depend on the compound and its form. Follow any storage guidance provided for the specific material. Do not assume that the same temperature or handling conditions apply to every item in the catalog.

We do not currently publish verified shelf-life information for every product. Do not infer an expiry date from general online guidance. Contact us to ask what product-specific information is available.
