Quality control

The SteriPlast® sample scoop made of polystyrene is produced and assembled in our clean room of class 7 (10,000, except for the 1000 ml scoop), individually packaged for disposable use and then sterilised by gamma rays. The sample scoop is ideal for powders, granulates and pastes. The scoop with transparent cover can be closed immediately after sampling and the sterility and exclusion of contamination can therefore be safeguarded. Ergonomics were particularly important to us for the design of the sample scoop. The scoop stands horizontally due to the special handle design and the slightly angled front edge and can therefore be put down without the sample material trickling out.

The intrinsic quality of the various components, sub-assemblies and software is checked at each stage of design and manufacturing. During the pre-validation phases, performance, durability, and efficiency goals are meticulously assessed and cross-checked with the obligations defined in the specifications. These efficiency targets are cross-referenced and verified with our customer upon commissioning of the equipment, following the implementation of a duly developed validation protocol.

Particular Challenges of the Application: By tactile equipment, determination of the deepest point on a rough metal surface is neither simple or precise. As a consequence, often either too much material is removed, or the surface is still covered with defects which have to be eliminated by a following milling cycle. The equipment is arranged in parallel, so that the complete width of the slabs is covered. The sensors are calibrated to a common coordinate system and mounted on a movable gantry. Before measurement, the slabs are fixed in place. The scanners mounted on the gantry are guided over the measuring object, driven by an electric motor. The point cloud recorded by the four scanners is consolidated in a PC by means of the QuellTech image processing software which calculates the difference between highest and lowest point of the corresponding surface and compensates for possible inclination of the slab (detrending).
