On 7 December 2017, the Laboratory division acquired Rohasys B.V.

It is performing as expected and creating interest amongst the Laboratory division's customers.

On 28 February 2018, the Aerospace and Industrial division acquired the goodwill, business and trading assets of Keystone Filter ("Keystone") for cash. Keystone designs and manufactures a range of filter cartridges and housings for the food and beverage, drinking water, and chemical process markets in the US.
