Abstract: Fabrication of a microfluidic multi-temperature reaction device (MMR) and the design and fabrication of the equipment to drive various molecular biological methods on the device are provided. The device can be applicable, for example, to nucleic acid (DNA, RNA, cDNA, etc) amplification, cell lysis, reverse transcription and other enzymatic temperature sensitive and also temperature cycling reactions.

Abstract: Various embodiments of the present disclosure generally relate to molecular biological protocols, equipment and reagents for the extraction and fractionation of DNA molecules, from whole or lysed samples, in a single flow-through device.

Abstract: A pipette component for use in performing an experimental procedure with a fluid sample and a pipette, the pipette component including: a pipette interface configured to engage sealingly and separably with a body of the pipette; a tip interface configured to engage sealingly and separably with a replaceable tip; and an experiment region configured to receive at least part of the fluid sample by operation of the pipette, and configured to perform at least part of the experimental procedure in the experiment region using the at least part of the fluid sample.

Abstract: A telescopic captive fastener has a knob, a ferrule, a spring, and at least one sleeve. The sleeve extends telescopically between the ferrule and the knob.

Abstract: A captive screw including a screw and a ferrule is disclosed. One end of the ferrule is adapted for engagement to a hole in a panel to be secured by the captive screw. The screw has an annular flange that is captured within the bore of the ferrule. The screw has a shaft with a threaded portion. The threaded portion of the screw shaft can be made to extend from the ferrule to varying amounts as the screw is moved relative to the ferrule between extended and retracted positions. An optional spring may be provided in the ferrule to bias the screw toward the retracted position.
