Circular Pool

Presentation

The BIOSEB circular pool provides the ideal environment to carry out the Morris and Radial Water Maze tests for the study of memory in rodents.


Operating principle

The circular pool is manufactured in polypropylene and stands on a support with 4 wheels for easier displacement.
BIOSEB proposes a complete solution for water maze settings since the heater, the water circulation pump, the level controller and the electro valve for pool filling are contained in a unique control box. The level controller acts directly on the Electro Valve, turning it off when the liquid arrives to the corresponding height. The water temperature is thermostated between 22 and 32 degrees depending on the environmental room temperature.

For Morris Water Maze Test, 2 easily interchangeable platforms are supplied (80 and 110 mm) that can be located anywhere in the pool.
For Radial Water Maze, a removable-floating eight radial-arm maze structure and associated platforms can be provided upon request.

Both Morris and Radial Water Mazes may be associated with the SMART Video-Tracking system for detection and analysis of animal displacements and behaviour throughout the test.
