WALTHAM — Thermo Fisher Scientific Inc. said it received antitrust approval for its $2.1 billion acquisition of laboratory equipment maker Dionex Corp., bringing it one step closer to completing the deal.
The scientific instrument maker said yesterday that it is seeking similar clearances under antitrust laws of other jurisdictions.
Last month Thermo Fisher said the transaction would expand its business in the Asia-Pacific region and help it do more business in industries such as environmental analysis, water testing, and food safety.
Waltham-based Thermo Fisher expects to close on the acquisition later in the first quarter.
Its stock shed 23 cents to $56.14, while shares of Sunnyvale, Calif.-based Dionex added 13 cents to $117.93.
