  • Patent number: 10844341
    Abstract: A bioreactor outlet air conditioning system (10) has a bioreactor vessel (100) and a heat exchanger. The heat exchanger has a fluid flow path (196) from a headspace (108) in the vessel for venting air from the vessel, and a temperature control element (300) in thermal contact with the fluid flow path (196). The fluid flow path (196) may be defined by a disposable portion of the bioreactor vessel (100). A method of controlling evaporation within a bioreactor vessel (100), dependent on the required evaporation rate, adjusts the temperature of the temperature control element (300) to control the rate of evaporation of the liquid media (106) from the vessel (100), and may include monitoring fluids in the fluid flow path (196) to detect at least water content of the fluids exiting the vessel to adjust the temperature and control the rate of evaporation dependent on the detected water content levels.

  • Patent number: 10596663
    Abstract: The present disclosure relates to a method for high precision laser processing of sapphire with submicron-order section plane using a picosecond-order pulse laser which has high transmittance wavelength to sapphire. The laser triggers ultrafine phase transformation points or electronic state removal points from a lower surface of sapphire. After elevating focal points, a trace which is parallel to laser incident direction is formed. Under a chemical corrosion environment, points of the laser trace are arranged to intersect with other another according to the cutting route to form the corresponding phase transformation region and electronic state removal region. At the same time, by utilizing the catalysis effect of microthermal effect of picosecond laser on chemical corrosion, separation of the sapphire sample along the processing path is obtained.

  • Patent number: 9494465
    Abstract: A Raman spectroscopic apparatus analyzes a substance under analysis and includes a light source that emits light of a first wavelength, an optical device that adsorbs the substance under analysis and is irradiated with the light of the first wavelength, and an optical detector that receives light radiated from the optical device. The optical device includes a first structural member that generates charge transfer resonance in response to the light of the first wavelength and a second structural member that is less than or equal to 5 nm from the first structural member and generates surface plasmon resonance in response to the light of the first wavelength. The first structural member is made of a metal or a semiconductor, and the second structural member is made of a metal different from the material of the first structural member.

  • Patent number: 9217703
    Abstract: A photoacoustic flow cytometry (PAFC) device for the in vivo detection of cells circulating in blood or lymphatic vessels is described. Ultrasound transducers attached to the skin of an organism detect the photoacoustic ultrasound waves emitted by target objects in response to their illumination by at least one pulse of laser energy delivered using at least one wavelength. The wavelengths of the laser light pulse may be varied to optimize the absorption of the laser energy by the target object. Target objects detected by the device may be unlabelled biological cells or cell products, contrast agents, or biological cells labeled with one or more contrast agents.

  • Publication number: 20150147804
    Abstract: The present invention relates to a biochemical analysis cartridge having improved operability. More particularly, the present invention provides a biochemical analysis cartridge including an insertion-type sample cartridge and a reaction cartridge receiving the insertion-type sample cartridge, in which,as the sample cartridge is inserted into the reaction cartridge,a reaction solution chamber moves toward a broken part of a covertape so as to automatically supply the reaction solution stored in the chamber. The biochemical analysis cartridge having improved operability according to the present invention can induce the mixing between a sample and a reaction solution by simply inserting them into the reaction cartridge and a reaction thereafter, thereby minimizing the process of a measurer to intervene in the assay, and subsequently improving user convenience and operability.
