The 315D and 322D High-Speed Length Controllers gives physiologists the ability to control and measure length of single cells, fibers and whole muscle with ease. Highly sensitive motors allow complete automated control of length of a vast number of biological specimens such as skeletal, cardiac and smooth muscle, connective tissue, and compliant tissue.
These motors provide a range of length control and response times uniquely suited to the needs of the researcher. Our fastest model, the 315D, provides a step change of length in 350µs and a length frequency response up to 1.7 kHz. All models allow the researcher to resolve length changes as small as 1 micron. All models have less than 0.01 micron/mN isometric compliance. With tensile limits of 100mN (315D) and 200mN (322D), respectively, our high-speed length controllers have more than enough force for any tissue sample.
The front panel manual length control allows the researcher to set the steady-state arm position. In addition, circuit design prevents the motor from being operated beyond its safe limits.
