The electronics company has hired Bank of America Merrill Lynch to sell the assets according to Reuters, which cited two financial sources familiar with the deal.
It said potential bidders were due to be provided with information within the next two weeks.
The news comes amid a resurgence for large bids on healthcare companies by private equity as the market continues to pick up following the financial crisis.
Yesterday it was reported that scientific equipment group Thermo Fisher had beaten a consortium of private equity firms to acquire testing equipment maker Life Technologies for nearly $13bn.
Reuters said the Life Technologies’ board met on Saturday to review three takeover offers and chose Thermo over Sigma-Aldrich and a consortium including Blackstone, Carlyle, KKR and Temasek.
Life and Thermo Fisher are negotiating a price close to $75 per share, valuing the business at almost $13bn according to a source.
