1. Perfusion cuvette system PER1:
The perfusion of the cuvette is brought about by a roller pump
The cuvette has a volume depending on the desired preparation length:
For up to 32mm long preparations 1.5ml
For up to 6mm long preparation 0.5ml
2.Temperature Control between 37°C and 42°C
A complete solution change is performed within approximately 5s. A pre-warming loop adapts the temperature of the injected solution to the temperature of cuvette system.
The regulator unit for the temperature control adjustable between 30°C and 42°C is integrated into the Force Transducer Bridge Amplifier BAM11.
3.Force transducer for the Muscle Tester
KG4 range 0 – 50 mN, resolution 0.3 mN; Papillary muscle, trabeculae ;small skeletal muscle, muscle rings
4. Stimulator STIM
The stimulator STIM can be operated independently from any software as a “stand alone” instrument
single and repetitive stimulation
repetition stimulation frequency 100Hz-0.01Hz
external trigger input and output
delay between trigger and stimulation 5ms-500ms
duration of the stimulus 0.1ms-10ms
amplitude of the stimulus 0-30V (bipolar) 0- 60V (monopolar)
optional negative mirror stimulus following the positive stimulus
gate-able output for defined duration titanic contractions
instrument can be controlled by the program MUSCLEDATA
output is isolated from ground
5. Field electrodes for the Muscle Tester FIEL
6. Sarcomere Length Detection set SARCSC
The Laser diffraction is evoked by a 5mW Laser diode
The diffraction pattern is analyzed with a screen.
(A one dimensional camera for the analysis of the lser diffraction pattern is available)
7. Data Acquisition System DAS
The data acquisition system DAS is a muscle specific system acquiring and evaluating the acquired data.
The system contains a chart recorder part acquiring continuously data and an oscilloscope part acquiring data after trigger pulse. Both systems run at the same time.
The system controls the Length Control unit LCCU, the Constant Load unit COLU and/or the Vibration unit VIBU, acquires the data of the corresponding experiments and evaluates them.
The system operates the stimulator STIMAMP and STIM for titanic contractions and allows adjusting the proper delay for the motor action.

The force transducers of the KG - series cover a large range of detectable forces. The transducer with the highest sensitivity has a resolution of 0.2µN, sufficient to measure the force of single heart cells. All transducers are extraordinary rugged withstanding even extreme overload forces. This allows using very convenient fiber mounting devices. Special stainless steel tweezers for fiber mounting are available.
