Learn how the SI-BAM21-LC optical force transducer amplier works with the rest of the SI-H line.

Eliminating the Resonance Frequency with the Anti-Oscillation Unit

Posted: Thursday, February 13, 2014

Learn how the anti-oscillation unit is used to eliminate symphonic resonance during muscle physiology experimentation.

A Typical Constant Load Experiment

Posted: Thursday, February 13, 2014

The SI-COLUB constant load module lets you maintain a constant force, muscle length or sarcomere length rather than keep the total length of the preparation constant during an isometric contraction. Read more here to understand how the SI-H constant load module is programed for muscle physiology experiments.

Constant Load Modes Available for Muscle Physiology Experimentation

Learn about the three different modes of the SI-H Constant Load module: Constant Load, External Loop and Bypass modes.

Measuring the Relationship between Force, Energy Consumption and Calcium Concentrations in Muscle Fibers using WPI-SIH Research Systems

Posted: Wednesday, February 12, 2014

Historically, a light source, filter wheel and photomultiplier were used to excite the dye at the proper wavelength. Now, using LED modules, we have much greater control over the measurement cycle. You can set the length of time each LED fires and establish the firing sequence. In addition, you can define the intensity of the LED signals, determine the number of readings used to calculate the rolling average of the ratio displayed, and set the photomultiplier filter frequency.

SI-CTS200 has a Rotating Cuvette

Posted: Wednesday, February 12, 2014

The SI-CTS200 system utilizes a unique rotating bath to dramatically improve experimental throughput. The rotating bath is designed to orient cells in the XY plane so that no physical manipulation of the position of the cell itself is required prior to capture by the grabbing devices attached to the force sensor and linear actuator.
