Animal research veterinary anesthesia workstation ACS-4A

for rodentstransportable

Product overview：
ACS-4A multi-channel small animal inhalation anesthesia machine is an upgraded integrated multichannel anesthesia system, equipped with 1 induction circuit and 4 maintenance circuits. It enables simultaneous maintenance of anesthesia for up to four animals and synchronous induction, meeting the needs of multichannel pipeline experiments. Inhalation anesthesia offers rapid recovery, precise control, high surgical success rates and minimal metabolic involvement, and is widely used for mice, rats, guinea pigs and other small and medium experimental animals.

System and components：
The ACS compact inhalation anesthesia system is an optimized development based on the ABS (Anesthesia Basic System) series. It uses an original imported vaporizer calibrated individually at the factory, with low sensitivity to temperature, humidity and pressure variations and stable, uniform output concentration. Optional multichannel anesthesia modules allow extension to control 2/3/4/5 rodents simultaneously.

Main features：

• Imported vaporizer, stable and sealed: original imported vaporizer with high-precision temperature compensation, output accuracy of 0.1%, stable output and good sealing; adjustable anesthetic concentration 0–5%.
• Precise control and clear observation: glass-tube oxygen flowmeter with total flow adjustment range 0–4000 ml/min; single-channel flow adjustment 0–100 ml/min, suitable for low-flow anesthesia in small animals; flowmeter includes digital magnification for clear observation.
• Separate induction and maintenance control, true four-channel design: induction channel is independent of maintenance channels, providing one additional complete anesthesia channel compared with similar devices; enables simultaneous induction and maintenance to improve experimental throughput, suitable for workflows requiring induction plus multichannel maintenance (e.g., animal imaging).
• Independent maintenance channel flow control: all four maintenance channels can be adjusted independently to match animal weight and anesthetic depth, improving agent utilization and enabling multi-species simultaneous experiments.
• Rapid oxygening and waste gas handling: integrated function to quickly purge anesthetic gas from induction boxes, reducing staff exposure risk and protecting operator safety.

Applicable subjects and use cases：
Suitable for mice, rats, guinea pigs and other small to medium experimental animals. Typical applications include animal imaging, neuroscience experiments and pipeline experiments that require parallel multichannel anesthesia.

Accessories and expansion：
Compatible with multichannel anesthesia modules to enable parallel control of 2/3/4/5 rodents; can be combined with respiratory and anesthesia accessory solutions to meet complex experimental requirements.

References and certification：
System components use original imported vaporizers calibrated individually at the factory and meet ISO9001 and EU CE quality certifications to ensure vaporizer stability and safety.
