Leak testers
Computerized, dry-air leak-testing instruments are available for production-line applications. The M-1000 series of leak detectors can be used as self-contained single-station testers or integrated into automated assembly and test systems. The units measure leakage rates from 0.1 to 20 sccm. Using a vacuum-fluorescent display and lighted indicators, the M-1000 series instruments report test parameters, dynamic test results, statistics, and final accept or reject status. Test data can be stored and recalled for display, printout, or downloading to standard spreadsheets. Intertech Development Co., Villeurbanne, France.
Vision sensors
Vision sensors with dual processors can perform simultaneous, dedicated vision processing within a network configuration. The In-Sight 4000 series consists of an ultra-high-performance vision sensor offering fast frame rates and accelerated performance; a high-resolution version for the inspection of small objects; and a compact, remote head camera model suited for harsh industrial environments. Additional accessories include LED-based lighting modules, an Ethernet workstation, network gateway modules, and industrial camera enclosures. Cognex UK, Milton Keynes, UK.
Laboratory microscope
An upright compound microscope features infinitely corrected optics with bright field, phase contrast, dark ground, and polarizing contrast options. The instrument is designed for use in all biological applications. In addition to microscopes and related accessories, the company manufactures fibre-optic inspection instruments, microscopy accessories, precision motorized stages, motorized filter wheels, and custom optical systems. Prior Scientific Instruments Ltd., Fulbourn, Cambs, UK.
Medical device testing
A company specializes in physicochemical, analytical, mechanical, biological, microbiological, virological, and clinical investigations of medical devices. The firm conducts performance and safety tests on devices and packaging materials for research and development, regulatory approval, and quality control purposes. mdt medical device testing GmbH, Ochsenhausen, Germany.
Electrical safety tester
An electrical safety tester is capable of performing tests routinely required in the production of electronic medical products. The Guardian 6100 can be programmed from the front-panel keyboard or remotely via an IEEE-488 or optional RS-232 interface. The unit's internal memory can store up to 99 test setups, each of which may have 99 steps. The company offers a selection of accessories for the unit, including test leads, voltage adapters, printer interfaces, and line-isolation transformers. Quadtech Inc., Maynard, MA, USA.
Testing connector
A miniature connector automatically seals miniature tubing and tube components for testing. Medical device manufacturing applications for the FE miniconnector include component testing of valves, catheter tubing, and miniature pumps. Air pressure actuates an internal piston in the device to compress an elastomer seal, making an instant leakproof connection. The user inserts the test piece into the connector and actuates the pilot pressure to perform the test. The connector is an alternative to clamp-on and push-on models that do not adapt as easily to automated or production applications. It is suited for use with tubing from 0.8 to 77 mm OD. WEH GmbH, Illertissen, Germany.

Benchtop universal testing machines are suitable for performing tensile tests on a variety of materials, especially plastics. The S-series can be linked with Windows-based software for control, data acquisition, analysis, and reporting. All machines include a complete after-sale package, which encompasses calibration and maintenance services. Tinius Olsen Testing Machine Co., Willow Grove, PA, USA.
Strength-testing machines
Universal strength-testing machines may be used to test the strength of catheters, sutures, dressings, prosthetics, medical tubing, hypodermic tubes and needles, and packaging. The company's integrated, stand-alone testing systems are available as benchtop and floor models. A PC software package can simultaneously display test traces from all load cells and will carry out required calculations. The machines also have a long-term data storage and retrieval system. The Testometric Company, Ltd., Rochdale, Lancs, UK.
