Abstract: A rack for holding assay tips with improved stacking is provided. The rack has guiding elements arranged near opposing edges of at least two substantially orthogonal side walls of the peripheral wall of the rack configured to provide an early alignment of the rack with a similar rack, such that assay tips received in the rack nest into the assay tips received in the similar rack when the racks are stacked.

Abstract: The invention relates to a homogeneous, non-dried, melt-extruded thermoplastic compound containing 30-60% by weight dry substance of native or chemically modified starch, maximum 11% by weight dry substance of at least one other biopolymer selected from the group consisting of carrageenan or a different polysaccharide or a protein, 20-45% by weight dry substance of at least one softener and a maximum of 20% by weight water. Said compound can be used, advantageously, to produce molded bodies such as soft capsules with increased impact resistance.

Abstract: The curable casting compound comprises an epoxy resin having at least one aminoglycidyl group in the molecule, a curative, and a fluorosurfactant. In the manufacture of products based on this casting compound, the shaping and curing operation can be shortened considerably.
