  • Testing Medical Devices and Package Integrity
    or system to locate leaks or to measure how much leakage will. occur over a certain period of time " [2]. Extending this definition, C.N. Sherlock, author. of the Nondestructive Testing Handbook lists three basic reasons for leak testing: To prevent material leakage loss, which interferes with system
  • Medical Device Link . Electrical Testing and Environmental Screening of Hybrid Microelectronic Devices
    leak detector, which measures the rate at which the helium is escaping from the package. A maximum allowable rate has been established that determines whether a part is passing. Gross leak testing repeats the eight-hour pressurization, replacing the helium with an inert liquid. The part
  • Highly Corrosive Media - Problem Solved
    be absolutely dry and leak free. In partnership with their engineers, Rotary Systems designed a flange mounted inline rotary union made out of corrosion resistant Hastelloy C276, Rotary's proprietary seals and, o-ring backers specified for hydrochloric acid. Special care was used in assembly, testing
  • Medical Device Link .
    the location of thin channel leaks. It features retrievable validation data and a graphic display. 143 California St., Newton, MA 02458. Featuring an oil-free diaphragm and molecular drag pump, a portable helium leak detector works in cleanrooms, pharmaceutical manufacturing facilities, and other
  • Medical Device Link .
    with nitrogen when loading a package to displace the ambient helium and to vent the chamber at the conclusion of the leak test.6 The turbo pump system removes the accumulated helium at the end of the test interval through valve D in preparation for the next test. Determining Leak Rate. Gross leaks ( >=1.0
  • Medical Device Link .
    not represent a true leak. HISTORY Historically, leak-testing of containment parts has involved some form of wet-bubble testing. The goal is simply to determine whether or not a part leaks. To do so, an operator pressurizes the part, submerges it in water, and then watches for a stream
  • Medical Device Link . Showstoppers
    in the pharmaceutical and medical industries. The sensitivity of the gas spectrometer permits the testing of packaged products with seal requirements ranging from gross leaks to ultrafine leaks, and an oil-free pump reduces the risk of inaccuracies from oil vapours. Jeffrey Morrow-Lucas, vice president of Leak
  • Medical Device Link .
    . "We fill a pouch (typically made of any combination of foil materials) with a 5% hydrogen mixture and nitrogen, and then we use a highly sensitive probe that gives us a quantitative measurement and the location of any leak. This type of testing is used on pouches designed for very critical
  • Connection and Joining Technologies for Sandvik SAF 2507 (R) (.pdf)
    resistance, and pressure advantages over 316L, 6 % molybdenum, and other conventional stainless steels due to controlled ferrite content, high nitrogen content, and smaller grain size. Connection and Joining Technologies for Sandvik SAF 2507�, High Performance, (MS-06-18-E, R1). Connection and Joining
  • Medical Device Link .
    . The device measures 4 x 8.5 x 19 in., weighs 18 lb, and accommodates 8.5 in. of travel. The durable tester is designed for many years of use in laboratory and industrial environments. Leak testers attain heightened sensitivity levels. A turnkey inspection system with micrometer-level testing
