摘要:
A vessel for use in a chemical, biological or biochemical reaction and having an electrically conductive coating which has been applied in fluid form whereby the vessel contents can be heated. Method and apparatus for coating the vessel and method and apparatus employing the vessel.
摘要:
Disclosed is a method of detecting a plurality of analytes in a sample comprising: selecting one or more primers, labelling each primer with a different dye, and placing in a reaction vessel; adding a sample to be analysed; subjecting sample to a multiplication process,- separating the amplicons according to size; quantifiying the sizes present and determining the colour of each size; comparing the resulting quantification and colours with known data to determine the nature of the amplicons. Also disclosed is an apparatus for carrying out said method.
摘要:
A vessel cup assembly (300) for receiving a chemical and/or biological reaction process vessel containing reactants and processing the reaction therein and comprising: a reaction vessel receiving portion; a heater portion (301); and a cooling portion (302); and wherein the assembly is of integral construction.
摘要:
Apparatus for biological or chemical reactions, in particular PCR, and comprising a heat removal module adapted to receive snugly a reaction vessel in such a manner as to create good thermal conductivity contact between the module and the vessel, the module being formed of a thermally conductive material having therein a channel adapted for the flow of a coolant liquid. Preferably it is constructed to receive an array of 96n microtitre wells formed of electrically conductive plastics (ecp) lined with an electrically insulative material.
摘要:
A thermal cycling apparatus and process wherein at least one reaction vessel is associated with a thermo-electric cooler (TEC) device, such as a peltier cell, arranged to provide both heating and cooling of the reaction vessel. One side of the TEC is associated with the said at least one reaction vessel and the other side is arranged in use to be maintained at a temperature intermediate the highest temperature and the lowest temperature used in the thermal cycling operation. Electric current is supplied to the TEC in one direction whereby the said one side becomes hotter than the said other side and then in the other direction whereby the said one side becomes cooler than the said other side.
摘要:
A process for the disruption of a biological cell comprising freezing, boiling or perhaps alternately freezing and boiling the material containing the biological cell using a thermoelectric cell a base face whereof is contiguous with a heat sink/source held at a substantially constant temperature and a working face. Apparatus for carrying out the disruption process comprises a peltier cell a base face of which is flexibly attached to a heat sink arranged to be kept at a constant temperature of around 50°C and a working face of which is contiguous with a reaction vessel or a reaction vessel holder. Reversal of the voltage in the peltier cell enables the working face alternately to reach below freezing and above boiling temperatures, and/or with use of a resistive wire on the vessel holder for heating with the TEC used purely for cooling The peltier cell base face is constructed of materials which tend to inhibit disintegration of the peltier cell brought about by expansion and contraction under heat.
摘要:
A nucleic acid amplification (NAA) reaction vessel comprising: two opposing major walls; a minor wall system attaching the major walls and thus defining a reaction chamber having a base, the major and minor walls being formed of a thermally conductive material; an inlet port permitting the introduction of fluid into the reaction vessel; a cap arranged for sealing the inlet port; and a light transmissive window at the base of the vessel reaction chamber; the vessel having a capacity greater than 100 microlitres. Process and apparatus employing the vessel are also described.
