Abstract: The invention relates to an object storage station having a front area for loading the objects, a back, and two sidewalls arranged on opposite sides, and having object holding rails with support surfaces that are arranged in pairs on opposite sides and extend substantially horizontally along the sidewalls in the interior of the object storage station. The invention is characterized in that the sidewalls have a plurality of identical, horizontally extending openings, which are arranged one above the other in the two sidewalls in identical number and position and always spaced at an identical distance from adjacent openings. The number of the openings in each sidewall corresponds to the number of the object holding rails of the sidewall and each of the openings has the same distance from the respectively closest object holding rail. The invention furthermore relates to a detachable mounting of the holding rails.

Abstract: Controlling the torque of a motor by driving a centrifuge rotor connected to the motor; increasing a motor torque of the motor to a specified level; detecting revolutions per minute of the centrifuge rotor; adjusting the motor torque based on detected revolutions per minute; decreasing the motor torque to a constant torque over a range of revolutions per minute; and increasing the motor torque when the detected revolutions per minute are outside of the range.

Abstract: An apparatus and method is provided to evacuate liquids from a water jacket of an enclosed clamber. An electronic valve, such as a solenoid can be actuated remotely to open and allow liquids to evacuate. A controller can also be used to actuate the solenoid or at a period of time or at an event.

Abstract: A centrifuge bucket, for holding a first article, further comprises a compartment for holding a second article, and an arrangement for securing the compartment to an outer surface of the centrifuge bucket.

Abstract: Methods and apparatus for a centrifuge control system, which are particularly suited for pre-calibrating temperature sensors.

Abstract: An apparatus and method for compensating gas loss in an incubator. A transducer can be used to monitor the gas pressure of various gases that flow into the incubator. By knowing the correct pressure that flows into the chamber, a faster and more accurate compensation can be done during enhancement or depletion of the gases in the incubator.

Abstract: A method and apparatus for a centrifuge energy management system prevents the energy level of a rotor from exceeding a predetermined containment limit for the centrifuge by monitoring the energy level and either terminating a run operation of the centrifuge if it surpasses the containment limit or reducing the rotational speed of the rotor.

Abstract: There is provided a method for limiting an operating speed of a rotor installed in a centrifuge system. The method includes the steps of (a) determining whether an actual change in energy required to accelerate the rotor from a first speed to a second speed is within a predetermined range of an expected change in energy required to accelerate the rotor from the first speed to the second speed, and (b) limiting the operating speed when the actual change in energy is not within the predetermined range of the expected change in energy.

Abstract: A high torque/high speed brushless DC motor system for controlling both the speed and torque of the motor including a rotor and a stator, the stator of the motor including a first, second and third winding. The system further includes means for sensing the position of the rotor and means for selectively configuring the first, second and third windings of the stator in a wye connection when the speed of the motor is less than a predetermined value and configuring the windings in a delta connection when the speed of the motor is greater than the predetermined value.

Abstract: A method and apparatus for securing a rotor to a drive cone in a centrifuge includes positioning a rotor upon a drive cone and providing a nut movable in an axial direction in the drive cone. A screw passing through a region of the rotor engages the nut, and a spring is located between a surface of the nut and a surface of the drive cone. By tightening the screw into the nut, the nut moves in an axial direction to compress the spring between the surface of the nut and the surface of the drive cone. The arrangement of the screw, nut, and spring prevents a loosening of the screw from the nut during operation of the centrifuge.

Abstract: An apparatus for notifying a user which gas tank(s) to connect to an enclosed chamber such as an incubator. The user inputs the desired setpoints for gasses such as O2 and CO2, and the corresponding gas level is determined. The determined gas level is compared with the setpoint of the gas and can display, which gas tank(s) should be hooked up to chamber.

Abstract: A lid holder for use in centrifuge systems, particularly suited for rotor lids. A lid holder including a lid support and a lid receiving end for holding a centrifuge rotor lid on a centrifuge that may not have a hinged door. A method for securing a centrifuge rotor lid to a centrifuge that may not have a hinged door.

Abstract: In a centrifuge comprising a drive shaft assembly, a diaphragm disposed about the drive shaft assembly reduces noise and vibration. The diaphragm permits the drive shaft assembly to pivot off a vertical axis while substantially limiting horizontal displacement thereof. Also, where a centrifuge includes a rotor shaft and a drive shaft, a member situated between the rotor shaft and the drive shaft substantially limits vertical displacement of the rotor shaft while allowing angular deflection of the rotor shaft with respect to the drive shaft.

Abstract: A centrifuge rotor cover attachment and release apparatus for automatic attachment and quick release. The apparatus has a knob with a bore extending therethrough with a cover connected to the knob. The apparatus additionally includes a housing having a passage. The housing is connected to the knob along. The apparatus additionally includes an adapter and plunger. The apparatus further includes a pair of biasing members, a slider member, and a moveable element.

Abstract: A method and apparatus is disclosed for setting energy saver sleep modes for use in a centrifuge systems. The centrifuge system contains an energy saver touch screen control which can be either manually set or automatically set to turn the centrifuge on or off at predetermined times. This allows the centrifuge system to be readily available to a user, resulting in lower wear and tear being placed on the major systems of the centrifuge and waste less energy.
