Description:

The HAVARD APPARATUS Small Animal Ventilator Model 683 is a versatile and reliable unit designed for use with small animals such as mice, rats, rabbits, and other mammals. It is ideal for small animal research, ensuring proper respiratory support while preventing excessive pressure on the animal's lungs. With a respiratory rate of 18-150 strokes per minute and a tidal volume range of 0.5-10ml, this ventilator provides great control over ventilation. It is perfect for any research or laboratory setting that requires precise and reliable respiratory care for small animals.

This model is furnished with two interchangeable piston/cylinder assemblies that allow for tidal volume settings from 0.5 to 5.0 cc (using the smaller piston) and 3.0 to 30 cc (using the larger piston). It is capable of working with animals ranging from 250g to 10kg (e.g., rats, hamsters, rabbits, small dogs, monkeys).

The ventilator is designed with a mechanical linkage system that ensures the piston always touches the end of the cylinder during each stroke, expelling all the air/gas mixture taken into the ventilator. Additionally, a positive mechanical slide valve is actuated by a cam on the motor, ensuring synchronized inspiration and expiration with the piston’s movement.

Key Features:

• Respiratory Rate: 18-150 strokes per minute for a wide range of ventilation needs.
• Tidal Volume Range: 0.5-10ml, adjustable for precise control.
• Piston/Cylinder Assemblies: Includes two piston/cylinder assemblies for different tidal volumes (0.2 to 5.0 ml/breath with the smaller piston and 1.5 to 30.0 ml/breath with the larger piston).
• Interchangeable Syringe Types: Choose between a 5cc or 30cc syringe based on your needs.
• Non-Toxic Autoclave Tubes: Includes Nalgene 8000 non-toxic autoclave tubes (3/16'' ID X 1/16 wall).
• Animal Weight Range: Suitable for animals from 250g to 10kg (e.g., rats, rabbits, small dogs).
• Synchronizes Inspiration and Expiration: Positive mechanical slide valve ensures synchronized breathing cycles.
• Gas Compatibility: Compatible with any non-explosive gas/air mixture.

Specifications:

• Electrical Data: 120V, 60Hz
• Respiratory Rate: 18-150 strokes per minute
• Tidal Volume Range: 0.5-10ml
• Syringe Options: 5cc or 30cc (selectable)
• Animal Weight Range: 250g to 10kg (e.g., rats, hamsters, rabbits, small dogs, monkeys)
• Nalgene Tube: 8000 non-toxic autoclave tube, 3/16'' ID X 1/16 wall
• Piston/Cylinder Assemblies: Two piston and cylinder assemblies included (0.2 to 5.0 ml/breath and 1.5 to 30.0 ml/breath)
• Dimensions: Compact and easy to integrate into small animal research setups

Model 683 for small animals from 250 g to 10 kg (22 lb) e.g. rats, hamsters, rabbits, cats, monkeys, small dogs, etc.

The Model 683 Small Animal Ventilator comes standard with two piston and cylinder assemblies. The smaller piston (which comes installed) allows tidal volumes to be set from 0.5 to 5.0 cc in 0.5 cc increments and the larger cylinder allows tidal volumes of 3.0 to 30 cc in 0.3 cc increments. Setting the cylinder stroke between gradations it is possible to achieve finer resolution in tidal volume settings. 

The 683 Ventilator features a numerical LED to display 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. 

Different overhaul kits are available from Harvard Apparatus website for the 683 ventilator model and are specific for the type of cylinder used. Overhaul kits include complete instructions and replacement parts.
