All ventilators operate on the flow-time principle. This method uses a constant flow of gas, which is gated into the animal for a known time, thus producing a known volume (flow x time = volume). This simple but powerful approach gives great flexibility in setting ventilation parameters such as inspiration time, I/E ratio, and more; something that is difficult or impossible to accomplish with the older mechanical piston-pump technology. In addition, this contributes to the legendary reliability and long service life of our ventilators, since the only moving parts are a pair of long-life solenoid valves.
These are our most popular models, and provide reliable and safe ventilation of rodent-size animals. Inhalational anesthesia (Halothane or Isoflurane) is available for all models. Economical multi-animal setups are made easy by adding external valve assemblies. All models feature a built-in computer control interface for remotely-controlled applications.
