Flat Bottom Restrainers are manufactured from perspex cylinders mounted on a flat black perspex base. The restrainers give access through both extremes, by opening the respective tilting door that is fixed by a screw at the upper part of the restrainer. Rodents can be immobilized by sliding the doors along the restrainer. A slot in the base of the door allows for the whole tail to be available for the pulse transducer and cuff installation, the i.v. drug administration or blood extraction.
The easy operation of the doors and its disposition on the extremes of the restrainer make the manipulation of the animal convenient and avoids the animal to be dragged backwards, protecting it from injuries.
