5%,Isoflurane;0-8%,Sevoflurane) , without effect by fluctuation of flux,
temperature, flow rate and pressure. The safety locking device well prevents
accidental volatilization of anesthetic agent.
The optional multi-channel component meets the induction and maintenance
anesthesia for up to 5 animals.
With the locking structure for preventing accidental stating and protection
structure in closed state, ensure the system security.
Accessories with various specifications (induction box, mask, anesthetic gas
recovery system etc,) will meet the need of animal with different species and
size.
