 We are pleased to report that we were pleasantly suprised with the number and quality of inquiries we received at the recent Quality Expo in Rosemont, IL. Given the current economic climate we went to the show with very low expectations but we found that while the number of visitors to the show was unmistakenly, and significantly, down over recent years, the interest and need for Tinius Olsen's equipment still remains solid. On our booth we had two bench machines, an H5kS and an H50kT, both tied to our new Horizon software and we found that most of our visitors were extremely interested in the capabilities and functionality of Horizon. |

 Crew Systems Corporation, a designer, developer and manufacturer of personal military life support equipment, has invested in another testing system from Tinius Olsen. With this new system Crew Systems staff will be testing, primarily, the strength and compressibility of various materials used in upper torso protection for military pilots. Having identified a need for another testing machine, Crew Systems’ Quality Manager, Tom Matkosky, made inquiries with many different suppliers and investigated the full range of equipment and capabilities of all these manufacturers and quickly settled on Tinius Olsen as their supplier of choice. “The entire staff at Tinius Olsen, from sales to servicing, were quick to respond to all of my inquiries and, I felt, the only supplier who not only actually listened to my needs and made sensible testing solution suggestions, but also worked with me and my budgetary constraints” says Matkosky. “Lives depend on the integrity of our products, so equipment that accurately measures the quality of our products is of primary importance to us, and, of course, our customers.” continues Matkosky, “I am extremely confident both in the capabilities of our new testing system, and with the top-grade support I get from Tinius, and because of this I’m equally confident we can continue to provide the product quality and integrity vital to our customers’ needs.” |

 Tinius Olsen proudly introduces a new moisture analyzer, the Hydrotracer, to the Americas market. This new analyzer is designed as a low cost alternative to existing equipment by using a chemical analysis rather than a heat and weight loss or microwave techniques. The key here is that our new system does not require any special chemical waste disposal, using small amounts of environmentally safe reagent to give repeatably accurate results.
The principle of operation is simple - the sample is heated to a pre-determined temperature such that any water in the sample evaporates. All the water vapor reacts with the calcium hydride reagent to release hydrogen; sensors measure the concentration of hydrogen, which is directly proportional to the moisture content of the reactor chamber. Comparable in accuracy and repeatability to more familar techniques, the Hydrotracer has a relative measuring range of 0.0005% to 5% moisture content and requires no special disposal of the final calcium hydroxide salt. The Hydrotracer is a perfect with Tinius Olsen's product line of testing equipment specifically designed for polymers, which includes equipment to measure melt index, impact strength (Charpy and Izod), stiffness, deflection temperature under load and Vicat penetration, tensile strength, tear strength, peel strength, compression set, puncture or burst strength, and many more. |

 One of the most widely used medical devices is the contact lens worn by millions of people daily.
The material science and technology in such a small device is amazing in the form of soft and hard lens with varying degrees of air permeability. Performing a strength and elastic stretch test on such a device is challenging, the lens must be held to prevent slippage during the test but not to cause fracture or damage, ambient conditions need to be managed simulating conditions of use. Another important test performed on contact lenses is a tear test, simulating someone rubbing their eyes while they are wearing lenses. This too requires special grips that can prevent slippage but still not damage the sample or induce a premature break or tear. Tinius Olsen has the expertise having successfully supplied strength test systems to contact lens manufacturers. |

 Impact testers are among the first instruments that plastics compounders, extruders, and molders consider when outfitting a lab. Historically, the choice between traditional falling-weight and pendulum impact testers seemed relatively simple. It was determined by the material, end-use application requirements, and the customer's preference for a particular type of test data.
