With offices in the USA, Europe and Asia, IonOptix Corporation - aka IonOptix LLC., makes quality ratiometric fluorescence and cell dimensioning data acquisition systems. Used in investigations ranging from characterization of excitation-contraction coupling to engineering cardiac tissue, the firm's clients include preclinical cardiovascular researchers working with isolated cardiomyocytes, tissue and blood vessels. Offering a range of high quality products, systems include those used for measuring calcium and contractility in isolated cardiomyocytes and vessels. The firm's MyoStretcher has a revolutionary OptiForce transducer for measuring force in cardiomyocytes, and culture pacing solutions for electrical stimulation of cultured cells. The new MultiCell high-throughput system is designed for the rigors of safety pharmacology and drug discovery screening in pharmaceutical research as well as the thorough characterization of EC coupling required for basic academic research - enabling simpler, faster acquisition and analysis of calcium and contractility without sacrificing the data fidelity.
