Calcium and Contractility Measurement in Isolated Myocytes

IonOptix is proud to offer fast real-time, turnkey systems for recording myocyte calcium and contractility.  These are unique in offering simultaneous acquisition of fluorescence photometry with digital cell geometry measurements.

All individual components are designed and engineered to work as part of a complete and integrated workstation. This approach enables precise, synchronous data acquisition.  The systems are fully integrated and installed on-site, so that the researcher can be up to speed within days of delivery. More than a general fluorescence system, our systems enable investigators to acquire cell length and sarcomere spacing with their calcium data.

Systems are offered with either of our two excitation light sources: the HyperSwitch or the µStep. Single, dual excitation and dual emission photometry is offered to cover all possible fluorescence probes with acquisition rates up to 1000Hz. Photometry acquisition rates are dependent on the light source and probe.  Our MyoCam-S provides up to 1000Hz cell dimension measurements, including simultaneous cell and sarcomere length recording. Our Fluorescence System Interface also permits the simultaneous acquisition of up to 4 channels of 12-bit analog data at a default rate of 1000Hz.


We can interface our system with an existing microscope or supply the microscope as part of the system. To provide a complete system for physiological measurements we also supply a number of peripheral items including digital field stimulators, chambers and heaters. Follow the link to find more information on these components.


As with all of our systems, we stand behind our products. When we install our complete systems we use your preparations to help get you started as quickly as possible. And when you need assistance we offer unlimited phone and email support for the lifetime of your system. Download the system description below for more information.

Our mission is your success!
