Business Combinations [Abstract]
Business Combination Disclosure [Text Block]	2.ACQUISITIONS In January 2013, we acquired 100% of the outstanding shares of AbD Serotec, a division of MorphoSys AG, for total consideration of $62.2 million (net of cash received of $7.3 million). This acquisition was accounted for as a business combination as AbD Serotec represented an integrated set of activities and assets that was capable of being conducted and managed for the purpose of providing a return and therefore constitutes a business in accordance with GAAP. The amount of acquisition-related costs was minimal as Bio-Rad primarily represented itself during the acquisition process. This business acquisition is included in our Life Science segment's results of operations from the acquisition date. We believe that with AbD Serotec's comprehensive catalog of antibodies, we are able to offer our customers total assay solutions that can be validated on many of our research platforms for western blotting, multiplex protein expression, ELISA and cell sorting. The final fair values of the net assets acquired consist of definite-lived intangible assets of $44.0 million, goodwill of $14.9 million and net tangible assets of $3.3 million. A portion of the goodwill recorded may be deductible for income tax purposes.
