Tethered Infusion Systems for Lab Animal Research

Tethered infusion systems use a mounted syringe pump that is kept away from the animal. The benefits of the tethered infusion system include:

Rodent Infusion System
  • • Tethered systems allow constant physical contact with the pump, ideal when reservoirs require frequent changes.
  • • Easier to monitor pump operation. Optional software available with the SAI 3D Pump
  • • Reduced risk of breakage or malfunction from animal interference.
  • • Accommodates higher delivery volumes since the animal is not required to carry the reservoir. This is especially important for rodents where the pump weight can cause welfare concerns.
  • • A tethered infusion system makes it possible to change syringes and flow rates without disturbing the animal- this is especially important for safety pharmacology studies or other applications where human interaction needs to be minimized. 

                                      For tethered infusion, you'll need:
