    with a four-port cross-structure. The channels are filled with buffer (black) and a red dye. Left (a), the voltage applied is high at the upper port and low at the bottom port, causing the buffer and dye to move from top to bottom and fill the intersection. Right (b), the applied voltage is high on the right

    . Wilco developed the LFC test method and is applying for a patent. Company officials describe LFC technology as a significant advance in leak detection. "We recognized that the available tests all involved a compromise, particularly the blue-dye test, which is messy and unwieldy," says sales

    and the project 's manager. "It doesn 't use any chemicals, reagents, or fluorescent probes, so there 's no need to modify the cell or incubate it with a dye. We take the cell in its physiological condition and make the light measurement in a very short period of time. ". With electrical-to-optical
  • Medical Device Link .
    HERMETICITY Hermeticity is commonly measured by dye-penetrant, bubble-emission, pressure-decay, microbial-ingress, radioactive, and mass spectrometer systems. All of these techniques are commercially available and can be used to detect leaks. Some like the bubble and dye methods can pinpoint
  • Medical Device Link . Compatibility of Medical Devices and Materials with Low-Temperature Hydrogen Peroxide Gas Plasma A new sterilization technique safely treated about 95% of the materials tested in an average of 75 minutes.
    and then sealing the dye in the porous anodized oxide layer that is electrochemically grown on the aluminum, the part is immersed in a second electrolysis tank following initial clear anodization. The second electrolysis tank typically contains specific metal salts, such as stannous sulfate, for coloring.7

    . Electric current sent through a gel pulls the DNA fragments along, and different fragment sizes can then be separated by the speed of movement into visible groups. The fragments that are tagged with a visible dye can be finally distinguished with a closely located miniaturized spectrometer. CONCLUSION
