Abstract: Methods and devices for preparing a biological sample for analysis are described. The biological sample from an organism has at least macromolecule having a primary structure that naturally degrades after the sample is removed from the organism. The method includes causing the biological sample to adopt a shape to permit rapid and uniform heating. The shaped sample is then rapidly and uniformly heated, thereby altering a secondary structure of the macromolecule while preserving its primary structure.

Abstract: Mixing device for handling of a cement product, comprising a carryable mixing unit for mixing of powder and water, a feeder unit for feeding in powder to the mixing unit and a flexible tube packet connecting the mixing unit to the feeder unit, wherein the mixing unit comprises a receiver part for powder, dosing equipment for powder, dosing equipment for water, a mixer for mixing of powder and water and an outlet pump for feeding out the finished mixed cement product. An advantage of the invention is that the mixing unit can be carried by one person, which simplifies the handling of the mixing unit. A further advantage is that dosing and mixing of a cement product takes place automatically. The mixing of the cement product thus may take place continually.

Abstract: An apparatus for injection molding or forming of work pieces, including closed profile work pieces, is provided that is less expensive and requires less space than known press apparatus. The apparatus locks a molding tool assembled from two or more tool pieces to define the shape of a molded or formed product using a frame, and one or more presses. The frame defines an interior space extending from a first end of the frame to an opposed second end of the frame for receiving a molding tool. The presses are placed within the frame and act in concert with the frame to apply pressure to a molding tool. The interior space is large enough to receive an assembled molding tool into the interior space of the frame, while not permitting removal of the tool pieces from the product within the interior space.

Abstract: The invention refers to a method for cleaning and sterilizing instruments within dental care, and incorporating the following partial steps, separately partly known in themselves, a) that the instrument, which is to be cleaned and sterilized is positioned in a treatment chamber, which is closed, b) that the instrument in the treatment chamber is washed with a washing medium, thus that all organic material in the form of internal, as well as any external deposits and coatings are removed, c) that the washing medium is discharged, d) that the instrument is sterilized during a time, which is short as compared to conventional sterilization, e) that the instrument is brought to take up a temperature appropriate for use, and f) that the instrument is lubricated if so needed, whereupon the instrument is ready for removal from treatment chamber for use.
