    Abstract: To heat a flowing liquid, an apparatus includes a heater block assembly having a heater block made of thermally conductive material. The heater block assembly has a tube inlet, a tube outlet, and a tube path between the tube inlet and tube outlet. Tubing extends through the tube path from the tube inlet to the tube outlet. The tubing is in thermal communication with the heater block. A heater cartridge, in thermal communication with the heater block, is configured to provide heat to the heater block for transfer to liquid flowing through the tubing between the tube inlet and the tube outlet of the heater block assembly. Circuitry is in electrical communication with the heater cartridge to control a temperature of the heater block by controlling operation of the heater cartridge.

    Abstract: Exemplary embodiments are directed to modular solenoid valve kits and associated methods, generally involving a valve body that includes a plurality of actuator section components and a plurality of head section components. The plurality of actuator section components includes a drive solenoid, a solenoid return spring, a stroke calibration collar and an actuator-to-head calibration collar. The plurality of head section components includes a needle, a stem return spring, a seal and a seat. The plurality of actuator section components and head section components are adapted to be interchanged to create a pull-through normally open valve, a pull-through normally closed valve, a push-in normally open valve and a push-in normally closed valve. That is, the kits and methods allow for modification of one valve type (e.g., a pull-through normally open valve, a pull-through normally closed valve, a push-in normally open valve and a push-in normally closed valve) into a different type.

    Abstract: An apparatus for use in a liquid chromatography system includes a chromatography port and a tubing assembly having a chromatography tube coupled at one end to the chromatography port. The end of the tube has an end face covered with a corrosion-resistant material, for example, gold. The corrosion-resistant nature of the material protects the end of the tube from corrosion or erosion, which improves the quality and reliability of a seal between the end face of the tube and a sealing surface of the port. Alternatively, or in addition to covering the end face of the tube with the corrosion-resistant material, a gasket covered with or made of the corrosion-resistant material can be disposed between the end face of the tube and the port. This gasket extends the reach of the tube to facilitate bottoming out the tube within the port.
