NexGen™ Rat 1800 Tall™ with Automatic Watering

NexGen™ Rat 1800 Tall™ Cage Base with Automatic Watering – Tall Reusable IVC Cage for Rats Meeting CCAC Requirements

The NexGen™ Rat 1800 Tall™ is a reusable individually ventilated cage (IVC) for rats with 1800 cm² of floor space and an internal height of 303 mm, forming part of the Allentown NexGen™ IVC system. It complies with CCAC (Canadian Council on Animal Care) requirements and other global standards for rat housing, permitting optimal bipedal posture and environmental enrichment. The cage docks into NexGen Rat 1800 Tall IVC racks (12, 15, 24, and 30 cages), which accommodate both Tall and standard Rat 1800 cages.

This version (Cat. no. 315351-2) is designed for automatic watering: when the cage is docked, it connects to the drinking valve of an IVC rack equipped with an automatic watering system (a stainless steel watering manifold with removable valves). Animals have continuous access to fresh water, and staff no longer need to fill, change, or wash water bottles. A version for bottle watering is also available (Cat. no. 315351-1).

Applications of the NexGen™ Rat 1800 Tall™ Cage Base with Automatic Watering

The NexGen™ Rat 1800 Tall™ Cage Base with Automatic Watering is a component of the Allentown NexGen™ IVC systems. The cage is therefore used together with a complete NexGen IVC rack and a watering installation prepared in the animal facility.

A central automatic watering system is part of the building infrastructure and typically includes water treatment and filtration, pressure-reducing stations, stainless steel room distribution piping, flexible rack connection hoses, rack manifolds with drinking valves, automated flushing and sanitization, and pressure and flow monitoring with alarms. The complete system – IVC racks, cages, and watering installation – is best suited to:

• New vivaria and facility modernizations where automatic watering is designed into the building infrastructure together with the IVC racks
• Rat facilities following CCAC and other standards that require taller cages, with many IVC racks where automatic watering replaces daily bottle handling
• Group-housed rats, including large adult rats, requiring continuous access to fresh, consistently treated water
• Long-term and preclinical studies where a reliable water supply and reduced cage handling minimize disturbance to the animals
• Facilities aiming to reduce washroom workload, water bottle inventory, and labor costs

For facilities without a central watering installation, the bottle watering version of this cage (Cat. no. 315351-1) is recommended.
