Abstract: This document describes an advanced laboratory platform rocker. An electronic circuit controls the rotation of the shaft of a motor. The shaft is coupled to the platform, such that the angular position of the platform is controllable, as a function of time, enabling non-periodic and non-steady motion. The rotation of the platform can be used to perform other functions, such as initiating the dispensing of liquid into a tray on the platform, and dispersing of liquid from a tray on the platform.

Abstract: This invention describes an advanced cooling system for a laboratory instrument to maintain laboratory samples at a predetermined temperature. The advanced cooling system uses an algorithm that incorporates information from at least one sensor and other operational parameters including thermal effects from the operation of the instrument.

Abstract: This document describes a capping-decapping device for screw-capped tubes or vessels. Caps of screw-capped vessels are inserted into an inverted channel. A high-traction surface and a low-friction surface comprise opposite walls. The cap unscrews as it is pushed forward, and is held in the device once unscrewed. The vessel can be recapped by pulling the cap back toward the user. Additional features of the device may be added to improve usability, such as making it easier to open caps of varying diameters or to detect the presence of a cap in the device.

Abstract: A centrifuge having two arcuate slots to receive resilient, bendable mounting flanges that each carry a plurality of test tubes in side by side relation. The resilience of the mounting flanges enables them to flex and assume either the curvature of the slot, or a linear configuration enabling the flanges to be suspended in a flat condition, such as on a test rack. The arrays of test tubes is attached to the flanges via living hinges that enable the flexing to occur. The advantages are that simplified identification of individual test tubes, as well as reduced likelihood of intermixing of spillage are realized.

Abstract: A system including a flexible, removable tube holder that flexes to fit either a straight rack or a centrifuge rotor slot. The system provides for the elimination of manual recording of the individual tubes, and provides for the transference of the tubes from the rack to the centrifuge and back, as a group.

Abstract: The present invention includes a system and method for the management of specimens ordinarily manipulated via tubes. The invention may include a flexible, removable tube holder that is linear when placed in a rack and curved when placed into a centrifuge rotor. The system provides for the elimination of manual recording of the individual tubes, and also provides for the transference of the tubes from the rack to the centrifuge and back in a group.

Abstract: The aim of the present invention is to provide a method of liquid flow control to an agitating instrument for mixing in a reaction vessel two or more substances of which at least one is a liquid phase. The vessel preferably comprises a container having an open upper end which may be advantageously surrounded by a rim, and a closed bottom end. The mixing device most preferably comprises a support plate upon which the vessel is placed. The flow control system dispenses and withdraws liquids from the reaction vessel. A control system can be integrated to dispense and withdraw liquids on a predetermined schedule, thereby automating otherwise tedious procedures.
