Size 5 Homeothermic Controlled Operating Table for Rodents

Size 5 Operating Table with Homeothermic Controller

The Size 5 Homeothermic Controlled Operating Tables for rodents have a heating, homeothermic temperature controller and consist of three parts: a probe, a control unit, and an adaptor box.The control temperature is preset at 37°C at the factory, but can be adjusted from 35° to 40°C by means of a control on the front panel.

  • Two different mounting bases available: tripod base or flat angled base
  • Choice of heating power supply or heating controller
  • Includes 4 paw holders
  • Capable of receiving thorax retractors and mounting ball joint holders

The Size 5 Homeothermic Controlled Operating Tables for rodents have a heating, homeothermic temperature controller and consist of three parts: a probe, a control unit, and an adaptor box.The control temperature is preset at 37°C at the factory, but can be adjusted from 35° to 40°C by means of a control on the front panel.

  • Three different mounting bases available: tripod, flat angled or flat bottom base
  • Choice of heating power supply or heating controller
  • Includes 4 paw holders
  • Capable of receiving thorax retractors and mounting ball joint holders

The core components consist of a 300 x 185mm (11.8 x 7.3 in) anodized aluminum plate and mounting base. Both sides of the plate have multiple slots for fixing the spring-loaded paw clamps and optional thorax retractors. Numerous slots allow both large and small animals to be held firmly in position for optimal surgical access. A block clamp with ball joint holder can be fixed onto the plate for holding various probes, electrodes, or cannulae. A 4 mm banana plug outlet is available when grounding the table is required, e.g. for ECG recordings.

Two different models of the mounting base are available– the traditional Tripod stand mounted on a ball joint allowing the table to tilt in multiple directions or the new flat angled version with a lower profile consuming less working height.

Probe
The flexible probe is a precision thermistor encapsulated in a bead of epoxy resin at the top of a flexible hollow plastic tube. The 1.6 mm diameter probe is 100 mm (4 in) long and has a 2 m (6 ft) long cable with plug for attachment to the control unit. It is suitable for a wide range of laboratory animals from adult mice to rats and guinea pigs.

The output of the temperature sensing probe is used by the control unit to proportionally control the regulated, low-voltage DC supply to the operating table. This method of control alleviates the interference problems associated with that of non-proportional control, found with high-gain recording systems.

Control Unit
The control temperature is preset at 37°C at the factory, but can be adjusted from 35° to 40°C by means of a control on the front panel. An LCD display on the control unit continuously displays the probe temperature. A horizontal LED bar graph indicates the level of power being delivered to the operating table. When core temperature is substantially below the desired temperature, the bar graph will indicate maximum power being delivered.

Adapter
The adapter consists of a separate box, which includes the permanent control of the operating table’s maximum temperature. It acts as a safety circuit by limiting the maximum temperature of the operating table to 40°C. This circuit uses a second thermistor probe built into the operating table.

Operating Table
The operating table is electrically floating, with respect to ground. However, one end of the heating element can be grounded by a switch on the front panel of the control unit. Special circuitry eliminates electrical noise thus permitting sensitive recordings.
