4-channel perfusion system for single cell and small tissue bath preparations, often used for electrophysiological studies and drug screening. 

The Radnoti 180101 systems are designed to maintain a perfusion solution’s temperature and aeration through the use of  water-jacketed reservoirs in combination with inline 158822 5ml heating coils.  Aeration is controlled via manifolds with individual Teflon Needle Valve aeration controls. The system can be adjusted to permit different gases to be used for hypoxia/ischemia or volatile anesthetic experiments. Water-jacketed systems are often more stable than small, electrically heated perfusate or syringe warmers because their reserve heat capacity is much larger, thereby reducing temperature fluctuations.  The 180101 Micro Perfusion system uses the 158821 heating coils to readjust the perfusate temperature just before it enters the receiving bath.  The water jacketed buffer reservoirs can be elevated to any point on the individual 48” stainless steel support rods to achieve a gravity fed pressure head.  Depicted with 1201042-250 250ml water jacketed reservoirs. Also available in volumes from 10 ml to 5 liters.  Fluids can be added during experimental runs through the use of the optional reservoir oxy bubbler with fluid return port (140143 series).  The 180101 system comes standard with 3/32 x 5/32 tygon tubing.  Polyethylene or Teflon tubing in sizes ranging from 1/32 in and 1/16 in, the standards for many preparations, to larger tubing for faster flows and micro-bore tubing for smaller volumes are all available as options.

The Radnoti micro perfusion systems can be controlled using optional accessory solenoid valve and peristaltic pump drive systems, allowing for complex delivery regimens to be initiated via optional computer based control system or the user’s pre-existing equipment.
