Sensor container for mounting a temperature sensor, and associated refrigerator
A refrigerator for storing products includes a sensor container configured to position at least one temperature sensor within a refrigerated interior in a cabinet of the refrigerator. The sensor container includes a main body portion enclosing a hollow interior space configured to receive a ballast liquid, and a plurality of dry wells which each extend generally horizontally between a closed end within the hollow interior space and an open end.

The temperature measurements therefore approximate the thermal response of products (such as blood) stored in the cabinet without necessitating submersible sensors or a risk of liquid leaks. The temperature measurements may be sent to elements such as a chart recorder, and a display and alarm device associated with the refrigerator.

Reagent wells mounted within the microplate to react with the contents of the open wells during a g-force acting upon the microplate. 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.

An attachment and release apparatus for attaching a rotor to a centrifuge drive assembly and for attaching a cover to the rotor. The apparatus includes a knob, a cover wherein the knob has a plunger disposed therein. The apparatus also includes an adapter having detents and a drive spindle having detents. In addition, the apparatus has at least one adapter moveable element retained within a passage located on the knob and least one drive spindle moveable element retained within an additional passage located on the knob. The apparatus also includes a biasing element disposed around one end of the plunger.
In a user interface to select a desired rotor from a set of rotors corresponding to compatible rotors for use in a centrifuge device, a home menu is utilized to access a previously selected rotor and an add menu is utilized to add the desired rotor in response to the desired rotor being absent from the home menu. In addition, the add menu includes the set of rotors.
