Rat/Guinea Pig Tubes
The CHT-250 shown here is ready for use. The tube is inserted into the
connector cone which attaches directly to the exposure unit. The pusher
is adjusted to properly fit the animal, keeping it securely in place.
The available wire support prevents the tube from detaching from the unit. There is an optional tidy cup, or kodet, attached to the open end of the tube which collects urine
The CHT-250 has several important features. The slots in the

The CHT-2500 is large enough to accommodate mature male rats and guinea
pigs. The tube shown is the open model which allows air from the system
to contact that of the surroundings. It fits into the same connector
cone and wire support as the rest of the CH tubes. It also uses the
same type of pusher to keep the animal in place. The CHT-2500 uses the same type of waste collection as the CHT-250. Waste is channeled through slits in the bottom of the tube, and collects in the tidy cup.
The CHT-XXXL is also available for animals that exceed the CHT-2500 weight or size limit.
It is the largest tube on the CHT line.
The closed tube prevents
air from the system from circulating into the surroundings and
allows experiments using toxins to be completed safely.
