我們將實驗人員的安全視為第一優先，因此，WPI麻醉系統提供3種呼吸裝置選擇，每種均帶有專利氣閥，可減緩流向緊密貼合的鼻罩(nosecone)的氣流。高敏感氣閥搭配鼻罩(nosecone)調節動物呼吸，以確保非再呼吸效率，可安全麻醉達12小時。
此外，導入室頂部的活性碳過濾罐，可釋放安全、經過濾的排出空氣回到房間內。EZ-FF9000型的氧氣沖洗按鈕，可在研究人員開啟導入室的門之前，安全的排除isofluorane。此系統適用於小動物麻醉，動物置入壓克力導入室進行麻醉，系統可輸送精確混合的氧氣與isofluorane。在導入室中，水熱式飼育盒加熱板(ATC2000)可保持動物體溫。開始麻醉後，動物可移動到加熱手術水床與置於鼻罩中。
 
本裝置是用於數百個設施中超過10年以上的舊款麻醉裝置升級版本。

3. 更為人性化的新型流量計配置
4. 內含2個流量計：
    流量計1：控制進入汽化器的流量
　流量計2：控制進入導入室的流量
5. 第二個流量計可讓使用者同時運行導入室和呼吸器
6. 氧氣沖洗按鈕，可在移出動物前清除導入室
7. 提把可安全、簡便的移動裝置
 
The safety of laboratory personnel is of primary importance. So, WPI's anesthesia system offers a choice of three breathing devices, all with a patented valve that mitigates the gas flow to the snugly-fitted nosecone. A highly sensitive valve regulated by the animal’s breathing works with the nosecone to ensure non-rebreathing efficiency and allow safe anesthesia for up to 12 hours.
In addition, an activated charcoal air  filter canister at the top of the induction chamber releases safe, filtered, exhaust air back into the room. The EZ-FF9000 even includes a push button oxygen flush to safely eliminate  the isofluorane from the induction chamber before you open it. This is the system of choice for anesthetizing small animals. Animals to be anesthetized are placed into the acrylic induction chamber, and the system delivers a precisely blended mixture of oxygen and isoflurane. A water-heated cage warmer or warming plate (ATC2000) is used to retain the animal body temperature while in the induction chamber. After the initial anesthetizing, the animal can be moved to the heated surgical water bed and positioned in the nosecone.
The Classic System is the upgraded version of the original Anesthesia System that has been used effectively for more than ten years in hundreds of facilities.  
    •  Accommodates animals ranging in size from neonate mice to rabbits
    •  Five outputs supply anesthesia to the induction chamber and up to four breathers
    •  New flowmeter configuration is more user-friendly
    •  Incorporates two flowmeters:
        Flowmeter 1)  Controls flow into the vaporizer
        Flowmeter 2)  Controls flow into the induction chamber
    •  The second flowmeter allows users to run the chamber and breathers simultaneously
    •  Pushbutton oxygen flush purges induction chamber before removing animals
    •  Carry handle facilitates safe, easy transport of the unit
