The ACS-4 multi-channel small animal anesthesia machine is an upgraded integrated multi-channel anesthesia machine designed specifically for multi-channel experimental needs. With one induction pathway and four maintenance pathways, up to four animals can be maintained under anesthesia simultaneously, and induction anesthesia can be performed simultaneously. It can better meet the needs of multi-channel experiments for experimenters.

Inhalation anesthesia has become the mainstream animal anesthesia method internationally in recent years due to its advantages of rapid recovery, easy control, high surgical success rate, almost no involvement in metabolism, and compliance with international animal welfare standards. It has been widely used by researchers worldwide. Animal experiments conducted using inhalation anesthesia techniques are more likely to be recognized by international peers for their research results.

With the increasing popularity of inhalation anesthesia, researchers have gradually increased their demand for portability, efficiency, and fluency in the use of inhalation anesthesia. With a deep consideration of this demand, Yuyan Instrument has repeatedly optimized and improved the original ABS (Anesthesia Basic System) series inhalation anesthesia system, and has specially launched a new ACS compact inhalation anesthesia system to optimize the user experience of inhalation anesthesia.

The core components of Yuyan Instrument's inhalation anesthesia system are imported volatilization tanks that comply with IS09001 and European CE quality certification. They are calibrated separately at the factory, and the volatilization of anesthetics is not affected by factors such as temperature, humidity, and pressure. The concentration is uniform and stable, and the safety factor for animals is high. It is very suitable for various small and medium-sized experimental animals such as mice, rats, and guinea pigs.

Main features:

1. Imported tank body, stable and sealed
The anesthesia canister is imported with original packaging and has high-precision temperature compensation function. The output accuracy is 0.1%, the output is stable, the sealing is good, and it is safe and reliable; Output concentration adjustable from 0-5%;

2. Precise control, easy observation
Accurate glass tube oxygen flow meter, with a total flow adjustment range of 0-4000 milliliters per minute and a single channel flow adjustment range of 0-100 milliliters per minute. The flow rate is precisely adjustable and suitable for low flow anesthesia of small animals. The flowmeter has a digital amplification function, making observation clearer and more convenient;

3. Induce and maintain independent control, "true" four channel anesthesia machine
The ACS-4A anesthesia machine adopts an induction and maintenance independent control design, which means that induction anesthesia is controlled separately and does not occupy the maintenance anesthesia channel. Compared with ABS-4A and its competitors, it can have an additional complete anesthesia channel and can achieve induction and maintenance simultaneously, improving experimental efficiency.
Application scenario: Pipeline experiments such as live imaging require induction and multi-channel maintenance anesthesia to be performed simultaneously

4. Maintain independent control of channel flow
The four maintenance anesthesia channels of ACS-4A can independently control the airflow, and the experimenters can adjust them independently in real time according to the animal's weight and anesthesia status, maximizing the utilization rate of anesthetics and saving anesthetics. In addition, independent flow control can also achieve simultaneous experiments of multiple species.
Application scenario: Different experimenters conduct experiments on different species of animals simultaneously; Animal experiments on different weight ranges, etc

5. Rapid oxygenation and rapid removal of anesthesia waste gas
Integrated rapid oxygenation function, capable of quickly expelling anesthetic gas from the induction box to prevent experimenters from accidentally inhaling anesthetic drugs when removing animals, effectively protecting experimenters.
