Abstract:
A rotor cover attach and release apparatus (10) for use with a centrifuge. The apparatus includes a knob (17), a cover (20) and housing that are both affixed to the knob. The apparatus also includes an adapter (22) that is connected to the housing along with a plunger (14)that is disposed within the knob and housing. In addition, the apparatus has a first moveable element (18) that is retained within a passage (28) located on the housing and a biasing element (24) located within the housing.
Abstract:
A compressor is controlled by generating and storing a compressor operation log. In addition, a compressor operation is selected from the compressor operation log in response to a sensor failure. Furthermore, the compressor is modulated according to the selected compressor operation in response to the sensor failure.
Abstract:
A microplate assembly comprising a multi-well microplate and a plurality of reagent wells proximal the multi-wells. The microplate includes a frame that houses a plurality of open wells in a rectangular array. Reagent wells mounted within the microplate to react with the contents of the open wells during centrifugation. The open wells function as a vessel for liquid samples that occupy predetermined spaces within the interior volumes. Each liquid sample remains within its predetermined space for all orientations of the microplate assembly.
Abstract:
An embodiment of the invention has a side panel with integrated shelving members and integrated locating members, both folded from the side panel. One method of fabricating the shelving members involves cutting a template of the shelving members and locating members onto the side panel and then folding the cut portions of the side panel to form shelving members and locating members.
Abstract:
Methods and apparatus for a refrigeration heat exchanger section useful in circulating a substantially non-CFC refrigerant mixture which comprises: a compressor means, an auxiliary condenser, a first condenser, a second condenser, a third condenser, a subcooler and a liquid/gas separator, wherein a cubcooled refrigerant liquid mixture taken as bottoms from the liquid/gas separator is distributed and expanded by a first expansion means and a second expansion means to form first and second expanded streams, respectively, such that the first expanded stream is returned to the auxiliary condenser and compressor in order to avoid overheating of the compressor.
Abstract:
Methods and apparatus for sterilization of laboratory equipment, which are particularly suited for sterilization of internal passages of a centrifuge centrate gate assembly.

Abstract:
An apparatus and method for displaying interaction or an appliance, such as an incubator, provides a display module having a display face angled relative to the vertical plane. The display face can be angled upwardly or downwardly to face the line of sight of a user.
Abstract:
Methods and apparatus for a two chamber freezer whereby both chambers (22, 24) can be maintained at a substantially constant ultra-low temperature, such as within the range of about -40° C to -80° C. Short term items may be stored in and accessed by the upper door (7, 10) from an upper chamber (22) while long term items may be stored in and accessed by the lower door (8, 9) in the lower chamber (24). The upper and lower chambers (22, 24) are thermodynamically independent of each other thereby reducing the power usage of the freezer.
