Thermal cycling apparatus for polymerase chain reaction (PCR) of nucleic acid is provided. Bath media in a first bath and a second bath are maintainable at two different temperatures. A transfer means allows the reactor to be in the two baths in a plurality of thermal cycles to alternately attain a predetermined high target temperature Tand a predetermined low target temperature T. A florescent imaging means images the reaction material during the thermal cycling. A powder-cleaning device mechanically removes particles of powder that adhere to the reactor, when powder is the bath medium in use in at least one of the baths.

Apparatus for polymerase chain reaction of nucleic acid

A method and an apparatus for thermal processing of nucleic acid in a thermal profile. The method employs at least a first bath and a second bath, the method further employing a reactor holder for holding reactor(s) accommodating reaction material containing the nucleic acid. The method includes maintaining bath mediums in the baths at two different temperatures; and alternately allowing the reactor(s) to be in the two baths in a plurality of thermal cycles to alternately attain a predetermined high target temperature T, and a predetermined low target temperature T, wherein the bath medium in at least one of the baths is a high thermal conductivity powder.

Rapid thermal cycling for sample analyses and processing

This invention relates to a multilayer filter. The filter comprises at least a first layer comprising a plurality of openings and at least a second permeable layer overlaying the first layer and reducing the size of the openings. The filter may further comprise one or more successive layers overlaying the second layer, wherein each layer further successively reduces the size of the openings. The filter may be used for separation of particles from fluid or gas. There is also provided a method for fabricating a multilayer filter.

Multilayer filter

The present invention relates to a membrane filter comprising a plurality of pores of substantially the same size. The membrane filter may be supported by at least one support (e.g. in the form of a support grid) and is able to handle a large flux and pressure in use. The invention also relates to a method of fabrication of such a filter membrane using a solvable mold.

Filter

The present invention relates to an apparatus comprising a substrate having at least one assay station. The at least one assay station has at least a first assay station channel and at least a second assay station channel and the first and second assay station channels each separately being in communication with the at least one assay station. The apparatus has an arrangement of at least first and second multipurpose channels in communication with the first and second assay station channels, respectively. The first multipurpose channel and first assay station channel have internal surface characteristics conducive to conduction of a sample solution therethrough. There is at least one sample fluid inlet in communication with the at least first multipurpose channel, and at least one isolation-medium inlet in communication with the at least first and second multipurpose channels. The at least one second multipurpose channel has an internal surface portion non-conducive to conduction of said sample solution.
