Harvard Apparatus Small Animal Rodent Ventilator
Model 683
Catalog Number 550000
• New and greatly improved version of the Model 683 for small animals from 250 g to 10 kg (22 lb) . rats, hamsters, rabbits, cats, monkeys, small dogs, etc.
Don't risk your research using an old style 683 ventilator which lend themselves to having spool valve issues causing animal distress. The entire air distribution systems has been redesigned and beefed up with new non-corroding stainless steel materials.
The Model 683 includes a 5 cc piston / cylinder assembly which allows tidal volumes to be set from to 5.0 cc in 0.5 cc increments. Setting the cylinder stroke between gradations it is possible to achieve finer resolution in tidal volume settings.
The 683 Ventilator features a LED display showing the respiratory rate which can be set from 18 to 150 strokes/minute.
Volume and rate settings can be adjusted while the ventilator is running.
The 683 Ventilator has four gas inlet and outlet ports: supply gas in, gas out (to animal), gas return (from animal) and ventilator exhaust. The ventilator exhaust can be attached to a column of water to achieve PEEP (positive end expiratory pressure) when long term animal ventilation is necessary.
