Abstract: Oven enclosure with microwave functionality, in which, at a short distance from an enclosure bottom panel, support elements are provided for accommodating a microwave-permeable base plate serving as a food holder.

Abstract: This invention relates to a broiling oven encompassing a) at least one cooking chamber (1), b) at least one microwave operating mode for cooking foods by means of microwaves and at least one thermal operating mode for cooking food by means of thermal radiation, with both cooking modes being selectable in alternative fashion or jointly, and c) at least one door (2) for closing off at least one access opening of the cooking chamber, said door featuring c1) at least one microwave shielding device (4) for preventing or reducing microwave leakage from the cooking chamber (1) when the door (2) is closed, and c2) a microwave-permeable shield (6) that is heat-resistant especially to the temperatures generated in the thermal operating mode, that essentially consists of glass or a glass-ceramic material and that covers the microwave shielding device (4), with the door (2) closed, on an inside surface of the door which in the closed state of the door (2) faces at least in part the cooking chamber (1), relative to

Abstract: An automatic pipetter utilizing a syringe having several openings at its end. A different tubing segment connects with each of these openings and extends into different vials of liquids. Of these vials, one contains a buffer solution generally used in appreciably greater quantities than the others. Another vial receives the liquids from the syringe. As a stepping motor partially withdraws the piston from the syringe, a tube leading to a vial with unmeasured liquid is open. When the stepping motor reinserts the plunger into to the syringe, the tube leading to the receiving vial becomes open while the other tubes remain closed. The tubing segments extending between the syringe and the vials include three sections. The section closest to the syringe, formed from polyimide, undergoes a minimal change in its volume notwithstanding the negative and positive partial pressures exerted by the piston.
