This new line of restrainers is available in heated and unheated versions. They are made of clear acrylic and are not autoclavable.The Restrainers are cylindrical and are mounted onto a flat sturdy base. They have a series of holes on each side to facilitate injections. The length is adjustable by inserting a removable headgate into one of several slots.
The Heated Restrainers will maintain an animal at a constant temperature of 37.8°C (100°F). They are ideal for use when performing indirect rat tail blood pressure studies or when taking blood samples from the tail since the animals often shut down the blood circulation to their tails when the room temperature drops below 23.9°C (75°F) as part of a mechanism to maintain body temperature.

The Heated Restrainers have a heating strip with an integral sealed thermostat. The strip slides into the bottom of the Restrainer. The animal does not come into contact with the heater. A special unbreakable thermometer indicates the Restrainer temperature from 31° to 40°C (88° to 104°F).

The Heated Animal Restrainers are for 115/230 volt use and are supplied complete with Restrainer, Heating Pad and Thermometer. The Restrainers are also available in an unheated version.
