Using proprietary ElectroForce controls and linear motor technology, the DuraPulse™ Heart Valve Test (HVT) instrument achieves smooth waveform fidelity and precise control for accelerated heart valve durability testing. Automatic feedback control and independent test chambers ensure that established test conditions are maintained throughout the test. The DuraPulse HVT instrument provides testing to the ISO 5840 standard for heart valve durability assessment.
DetailsNew Castle, Delaware, USA. March 29, 2017 – TA Instruments is pleased to announce three recipients of the “Distinguished Young Rheologist” award: Dr. Simon Haward, Research Associate at Okinawa Institute of Science and Technology, Dr. Quan Chen, Associate Professor of Chemical Engineering at the Changchun Institute of Applied Chemistry, and Dr. Takashi Uneyama, Associate Professor…
DetailsOverview The TA Instruments Hands-on Training Courses are paid courses taught in-person in the lab in front of the instruments. Class size is limited to ensure an ideal learning environment. Topics include basic theory, instrument and software operation, calibration, and applications. All courses are fee-based. These courses are currently available for the Discovery 25/250/2500 DSC…
DetailsGerald Fuller – Interfacial Rheology OVERVIEW Interfacial rheology dominates the behavior of many complex fluid systems. Whether the system is characterized by a fluid-fluid interface or fluid-air interface, these characteristics influence the behavior of biological systems, oil recovery, personal care products, food and more. Learn about the basic forces that drive interfacial dynamics and stability,…
DetailsA lignite coal sample and several petroleum coke samples have been gasified in the new Discovery HP-TGA 75 and 7500 instruments using carbon dioxide and steam as gasifying agents. The evolved gas atmosphere was analyzed with online mass spectrometry to detect the generated syngas components.
DetailsOVERVIEW Large amplitude oscillatory shear (LAOS) is used increasingly as a tool to measure the nonlinear viscoelastic responses of soft solids and complex fluids. For many material systems the common practice of reporting only “viscoelastic moduli” (typically corresponding to the first harmonic Fourier coefficients G’1(w), G”1(w)) is insufficient and/or misleading in describing the nonlinear phenomena.…
