AI Technical Summary

Problems solved by technology

However, such microtiter plates and / or PCR plates are relatively large and heavy, e.g., having a footprint of approximately 14 inches by 14 inches or more; relatively expensive; and complex to operate since speed and run times must be programmed ;has a relatively long processing time, as large indexing rotors take 20 to 40 seconds to come up to speed, require the same amount of time to decelerate to a stop, and require considerable safety features, such as a cover locking system

Embodiment Construction

[0016] figure 1 A cross-sectional view of a conventional microtiter / PCR plate centrifuge 100 is shown with a generally oppositely positioned tray 110 (position A) attached to a rotor arm 125 via a universal or articulating joint 120 . As an input voltage (not shown) is applied to the motor unit 130 to rotate the arm 125 to a desired speed, the horizontal tray 110 swings out to a substantially vertical position (position B). In this vertical position, any PCR plates (not shown) positioned in tray 110 are also positioned vertically, and centrifugal force forces solid material within the PCR plates to the bottom of the vials within the PCR plates.

[0017] figure 2 A perspective view of an exemplary embodiment of a microtiter / PCR plate centrifuge 200 in accordance with the principles of the present invention is shown. In the exemplary embodiment, top turnplate 210 (ie, rotor) includes at least one set of generally oppositely positioned slots 220 . Slot 220 represents an openi...

Abstract

A microtiter plate centrifuge is disclosed. A centrifuge comprising: a motor assembly; a shaft extending perpendicularly from the motor assembly; a rotor assembly attached to the shaft, the rotor assembly including at least two slots positioned symmetrically with respect to the shaft; and a channel corresponding to the slots for each slot in the . Channels extending from the rotor assembly are adapted to hold the microtiter plate in a vertical position. Also included is a base plate that engages brake pads that, when engaged, create sufficient friction to stop rotation of the rotor assembly.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 12 / 317,880, filed December 30, 2008, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to the field of centrifuge medical devices, and more particularly to microtiter plate centrifuges. Background technique [0004] Methods for separating solid components from fluids are well known in the medical field, for example. In application, vials are placed in centrifuge sleeves and spun at various speeds. Centrifugal force created by spinning the vial causes heavier particles within the vial to be forced to the outer rim or lower portion of the vial. [0005] In another type of centrifuge, to rotate the microtiter and / or PCR plate, the microtiter and / or PCR plate is placed horizontally in a swing-out tray and then rotated to a substantially vertical position. A PCR plate represents a specific ...
