A centrifuge, especially a flow-through centrifuge free of rotating seals, for centrifuging biological fluids has a stand on which a frame (1) is rotatably mounted. A centrifuge chamber (3) is rotatab
If you have an idea, feel free to contact us and let us know. There are all sorts of pieces of equipment we are thinking about, but for now, this basic set is something good to focus on getting done and fine-tuning before broadening our collection....
FIG. 2 is a partial cross-sectional configuration diagram of an oil diffusion pump of the centrifuge; FIG. 3 is a cross-sectional diagram illustrating arrangement of a heater and a thermistor and a position of an oil surface inside a boiler in the oil diffusion pump; ...
According to the block diagram shown in FIG. 1, a motor 10 of the centrifuge (not shown) is driven by a motor drive unit 15, which receives the control signal that defines the desired motion of the centrifuge. In the control method, pulses of an angle sensor 11 coupled to the motor ...
A pressure plate in the form of a body of material, such as a metal plate, having a predetermined mass is slideably disposed in the radial direction between the first bag and the center of rotation of the rotor. This pressure plate is suspended so that it is free to move radially agains...
(notwithstanding air is free), they allow for extremely fast drilling by blowing the drilled solids out of the well and allowing the drill bit to remain clear of debris. However, they are seldom used because the presence of formation liquids causes “air drilling” to immediately stop working....
