To find a Certificate of Analysis, enter a valid catalog number (excluding the hyphen) and lot or control number (not the Manufacturing Lot number) below. If you need assistance, please see our Help section.
Note: If you have a kit, try looking up the Certificate of Analysis using the kit information as well as the information for the individual components. For example, for Precision Plus Protein™ Standards, we issue COAs according to the vial lot number (35xxxxxxx), not the kit lot number (31xxxxxxx).

All Bio-Rad products are guaranteed to meet the specifications listed in our catalog. Should a Bio-Rad branded product fail to meet specifications during its warranty period, it shall be repaired or replaced at Bio-Rad's discretion. Warranty periods are listed on quotations for specific products; however, instruments generally receive 1 year of warranty coverage from the date of shipment or installation. Instrument warranties do not include consumable parts, such as lamps, lasers, and platinum wire. Repairs have different warranty periods. Chemicals and other consumables are warranted through their expiration date, or for 1 year from shipment if no expiration date is indicated. Non-Bio-Rad branded products, such as computers and computer peripherals, are covered by the original equipment manufacturer's warranty. Warranties are not transferable from the original purchaser. Warranty coverage may be void if the product is moved outside of the country where the product was originally purchased. An optional extended warranty program is available. For information, call 1-800-4BIORAD, and select Inside Sales.
