Detailed Description
The AutoMate Scientific Valvelink perfusion system allows real-time or pre-programmed liquid switching in perfusion, physiology, biophysics, electrochemistry, or general liquid-handling research applications. The BubbleStop™ Syringe Heater with integrated temperature sensor and feedback will ‘off-gas’ in the syringe reservoirs to prevent bubble formation in the perfused solutions.
8-channel general-purpose stimulus generator for current and voltage-driven electrical stimulation with integrated stimulus isolation unit for each output channel. Operating in Download and Streaming mode (continuous downstreaming of pulses from connected computer).
