Toxic Substances in Our Daily Life
28 Nov 2014Due to the huge diversity of plastics, the requirements for sample preparation can vary greatly. In this application note, the RETSCH SM 300 cutting mill, ZM 200 centrifugal mill and CryoMill are used to grind a range of plastics, including soft and elastic plastics. The prepared samples can then be subsequently analyzed for PAH and plasticizers.

Shakers, Stirrers and MixersShakers, stirrers and mixers are used for mixing liquids and solids for laboratory applications. There is a wide range of laboratory mixing equipment available, including magnetic stirrers, orbital shakers, linear shakers, microplate shakers, 3D gyratory rockers, rotators & vortexers. Additional platforms and clamps can also be attached to shakers to increase capacity. Find the best shakers, stirrers and mixers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Mechanical TestingMechanical testing explores the elastic and inelastic nature of a material when force is applied. A mechanical test shows whether a material is suitable for its intended application by measuring hardness, tensile strength, elongation, elasticity, and fatigue limit.GrindingPolymersPolymers are large molecules made up of many repeat units. Natural polymers such as DNA and proteins are essential to life, whereas synthetic polymers such as polystyrene and polyethylene are used widely due to their functionality. Typical techniques for analysis include GPC, SEC, DSC, FT-IR and NMR.Sample ProcessingSample processing is required to prepare samples prior to analysis. Technologies used for sample processing include homogenizers, grinders, mills and mixers.
