Abstract: A transport device unit for a transport device assembled using a plurality of transport device units is presented. The transport device unit comprises a base plate module with a base plate for fixing the transport device unit to a support frame, an actuator module with a plurality of electro-magnetic actuators, where the actuator module is supported by the base plate module, and a driving surface module with a driving surface element, where the driving surface element is arranged above the actuator module covering the actuators and configured to carry sample container carriers. A transport device, a system for at least partially disassembling the transport device, and a laboratory sample distribution system comprising a transport device are also presented. In addition, a laboratory automation system comprising a laboratory sample distribution system is also presented.

Abstract: A method is provided for producing polyurethane-based cores and moulds, using a mixture of particle-formed material such as sand, a bonding agent containing a polyisocyanate compund and a polyhydroxy compound and if necessary a solvent, after which the mixture is shaped to a desired form and hardened by means of a catalyst, wherein the polyhydroxyl compound consists of one or more aliphatic or aromatic polyethers, together with a hydroxyl compound for initiating the catalyzation, which hydroxy compound consists of an aromatic compound with at least two OH groups which directly, or via a methalene group, are linked to a carbon atom in the aromatic nucleus.
