Air-matrix digital microfluidics (DMF) apparatuses and methods of using them to prevent or limit evaporation and surface fouling of the DMF apparatus. In particular, described herein are air-matrix DMF apparatuses and methods of using them including thermally controllable regions with a wax material that may be used to selectively encapsulate a reaction droplet in the air gap of the apparatus; additional aqueous droplets may be combined with the encapsulated droplet even after separating from the wax, despite residual wax coating, by merging with an aqueous droplet having a coating of a secondary material (e.g., an oil or other hydrophobic material) that may remove the wax from the droplet and/or allow combining of the droplets.

Methods for forming arrays of droplets, and associated arrays of droplets, are generally provided.

Double-walled containment cells are described as may be used for storage, transport, and examination of a sample held within the cell by use of optical analysis techniques. A double-walled containment cell can include multiple types of windows that can be located as desired on the containment cells and thereby provide for optical access to a sample for multiple optical analysis techniques. Disclosed containment cells can be sized and designed for use with existing optical analysis systems, e.g., laser ablation, X-ray diffraction, spectral analysis (e.g., Raman spectroscopy, infrared spectroscopy, laser-induced breakdown spectroscopy, etc.), imaging analysis, etc.

A system for performing biological reactions is provided. The system includes a chip including a substrate and a plurality of reaction sites. The plurality of reaction sites are each configured to include a liquid sample of at most one nanoliter. Further, the system includes a control system configured to initiate biological reactions within the liquid samples. The system further includes a detection system configured to detect biological reactions on the chip. According to various embodiments, the chip includes at least 20000 reaction sites. In other embodiments, the chip includes at least 30000 reaction sites.

The invention relates to a method for tempering a plurality of capillaries, which are arranged on a carrier, wherein the carrier having a length, width and height receives the capillaries along the width of the carrier. The carrier has a recess in order to receive a tempering element so that the capillaries may be tempered in their central region by means of contact with the tempering element. According to the invention, the ends of the capillaries filled with samples are unsealed during tempering.

A test element for an assay includes: a cartridge having a housing which includes a priming pad capable of containing a liquid fluid, a wash port having an opening in the housing, and an opening for directly or indirectly applying a sample; and an assay device positioned within the cartridge in fluid communication with the wash port containing an analytical reagent.

The present invention is directed to a cap for a biochip storage well. The cap comprises a resilient sealant layer capable, under the application of pressure, of forming a vapour-proof seal with a line contact interface formation extending around the perimeter of a biochip storage well.

An assay assembly comprising the cap of the invention and a biochip storage is disclosed. Methods of sealing a biochip storage well using a cap of the invention are also disclosed.

A method of performing an optical measurement of an analyte in a processed biological sample using a cartridge is provided. The cartridge is operable for being spun around a rotational axis. The method comprises: placing the biological sample into a sample inlet; controlling the rotational rate of the cartridge to process a biological sample into the processed biological sample using a fluidic structure; controlling the rotational rate of the cartridge to allow the processed biological sample to flow from the measurement structure inlet to an absorbent structure via a chromatographic membrane, and performing an optical measurement of a detection zone on the chromatographic membrane with an optical instrument. An inlet air baffle reduces evaporation of the processed biological sample from the chromatographic membrane during rotation of the cartridge.

A method and apparatus for opening a reaction vessel having a body forming a volume for liquid, and a lid. In the method at least one reaction vessel is placed on a transport vehicle and the reaction vessel is positioned on the vehicle so that the vessel's rotation about its own axis is prevented. Then, the at least one reaction vessel is transferred on the vehicle and a guide rod, attached to the lid that is attached by a hinge to the reaction vessel, is pushed by the movement of the vehicle against a guide surface that forces the lid to turn on the hinge so that the lid is at least partially opened.
