Rodent Ventilator – Volume Controlled

Product Code:7025/7125

A positive pressure pump (according to Starling’s Ventilator method) for small animals. Assists with breathing during anesthesia and surgery or when an animal has an injury or illness that requires respiratory support.

Highly accurate, rate displayed digitally, choice of cylinder/piston assemblies (from 0.05-0.5 ml to 20-100 ml), quiet, high quality, robust with a long lifetime. Options include Start/Stop model for advanced electrophysiological-pharmaco­logical investigations.

  • Assists or stimulates respiration in a subject which is not breathing or is unable to make sufficient respiratory effort on its own.
  • Mechanical ventilation is a method to assist or replace spontaneous breathing.
  • For use with small animals including guinea pigs, rats, mice and small birds.

 Highly accurate, quiet, low maintenance, long life span

  • Highly accurate and reliable stroke rate for providing consistent volumes. Uses a variable speed geared motor (with no backlash) linked by a novel variable stroke mechanism. Volume is adjustable whether the pump is running or stationary. 
  • Stroke rate (per minute) is indicated on the 3-digit LED display. 
  • Caters for different sized animals with easily interchangeable 5ml, 10ml or 30ml cylinder/piston assembly. 
  • Flexibility in air channeling with four ports (Intake, To Animal, From Animal and Exhaust). Input can be room air or any other non-explosive gas mixture. Exhaust air may be partially or totally recycled or collected for analysis. 
  • Quiet operation. High quality and robust. Low sliding friction for practically no wear or tear for a long lifetime. 
  • Operation may be "paused" by an external TTL logic signal, such as a digital output from a data acquisition or imaging system.
  • Select Start/Stop Model for advanced electrophysiological-pharmacological investigations.
  • Product review: “We have four of your respirators in our extended lab and they are wonderful – as is your service” Dr. Nicholas Price, Monash University, Australia

Artificial ventilation, also called artificial respiration is any means of assisting or stimulating respiration in a subject which is not breathing or is not making sufficient respiratory effort on its own.
Mechanical ventilation is a method to mechanically assist or replace spontaneous breathing: this involves a machine called a ventilator.
