Protect Your Investment: The Instron BioCoat

Do you perform mechanical testing with an Instron BioPuls Bath, a homemade bath, or with wet specimens? Medical devices and biomaterials are often tested in a bath of water or saline heated to 37 °C (body temperature) to replicate a more physiologically accurate environment. While this creates an accurate simulation, using liquid can pose a risk of damaging your Instron system, since many of the frame’s electronics are housed directly under the liquid-filled test space. More often than not, the risk usually comes from filling and emptying the bath.

Are You a Statistic?

According to the Center for Disease Control and Prevention, motor vehicle crashes are the leading cause of death in the US among people ages 5-34. About 6,400 adults are injured in motor vehicle accidents every day. Still, nearly 15% of us don’t buckle up for every trip we take in our cars.

Industry Update: Mechanical Testing of Stents and Stent Materials

Stents are a wonderful creation of modern medical engineering that aid physicians and surgeons in the treatment of heart disease. Conditions, such as smoking, diabetes, and high cholesterol help promote atherosclerosis, the build up of fatty plaque within arteries, which can ultimately lead to heart attack and stroke.

What is 21 CFR Part 11 and How Does it Affect Me?

Have you heard of 21 CFR Part 11? If not, it is a set of compliance requirements that allow for safe and secure storage and submission of electronic records for industries regulated by the US FDA. In other words, this is the FDAs procedure for quality control of electronic data. Any company storing electronic data that could be audited by the FDA must comply with this set of requirements. Although the FDA still permits paper-based data storage and submission, this approach can lead to higher costs, increased time to market, decreased quality, and challenges with information storage availability, retrieval and portability, as compared with electronic methods.

Hobas Pipe USA Installs Giant Custom-Built Instron Frame

HOBAS® Pipe USA, a producer and supplier of fiberglass-reinforced polymer mortar pipe systems, produces pipe and pipecoupling products in a wide range of sizes. Worldwide population growth has increased the demand for bigger water supply and sewage pipes. Consequently, the pipe diameter range was set to increase beyond the size capability of their current testing equipment. They needed a system that could test their full range of products and they turned to Instron for the solution. The resulting testing system was so big that it was installed out in the open and the test building was constructed around the frame.

Selecting a Pressure Transducer for Your Capillary Rheometer

It is common to refer to pressure transducers by their full-scale range in megapascals (1 MPa is 145 psi). The accuracy is 0.25% of the full scale of the pressure transducer. To obtain the highest quality data, the recommended minimum pressure is about 10 times the accuracy and the recommended maximum pressure is about 90% of the full-scale range.

A Very Deep Investment

The challenges of testing Fiber Reinforced Concrete (FRC) go well beyond what we would normally think of with respect to concrete testing. The difference lies in the fact that most of the valuable information from an FRC test comes after the concrete fails. The ability of FRC to resist crack growth after the initial crack is determined by measuring the toughness (typically area under the curve) of the sample as it is deflected well past the first crack. All of these tests must be run under servo-control and one of the more common tests must be run using the measured beam deflection as the servo feedback. This can be very challenging as the specimen goes from being very stiff to very compliant after the first crack.
