Verder Group expanded the portfolio of its Scientific Division in the business segment of sample preparation of solids by acquiring ATM, a leading manufacturer of machines for metallographic applications. The instruments are used both in industrial processes and research to prepare solid bodies of metal or compound materials, usually followed by microscopic analysis. ATM’s headquarters are located in Mammelzen, Germany, where it employs 150 staff. ATM’s product range perfectly complements the offerings of Retsch, a leading manufacturer of laboratory mills for sample preparation and also part of the Verder Group.
