RWD Precise Impactor for Rat & Mice

The 68099II Precise Impactor is an instrument used for traumatic brain injury and spinal cord injury models. The system adopts pneumatic-electric control, which can precisely adjust the speed, depth, and dwell time to achieve precise impact. Touch screen design, convenient and friendly operation. The zero method uses a sensor contact mechanism to automatically detect the zero interface, which is sensitive and efficient. The standard cylindrical head hammers with different sizes are available. The parameters such as impact depth, velocity, and dwell time can be precisely controlled to ensure that the damage level is correct. It is an accurate tool with high efficiency, repeatability, and stability, ensuring reproducibility of the damage model.

Benefits:

  • Pneumatic electric control to ensure repeatability of the experiments.
  • High efficiency with automatic detection of zero interface to avoid the cumbersome manual process before the impact.
  • Rotatable design ensures that the brain and spinal cord are hit vertically and improves the repeatability of the experiment.
  • Color LCD touch screen interface with friendly and intuitive software.
  • Speed range: 0.5-5.6m/s, resolution 0.1m/s.
  • Control the dwell time and strike depth, dwell time range: 0.00-5.00s, resolution ratio 0.01s, depth range: 0.00-5.00mm, resolution 0.01mm.
  • A variety of cylindrical flat head hammers are available, with outer diameters of 1mm, 2mm, 3mm, 4mm and 5mm.
  • Supports a variety of gas supply, easy to connect oxygen tanks.
  • Solid, stable, and heavy frame.

RWD Rodents and Monkey Spinal Cord Impactor

RWD’s spinal impactor is a unique tool to evaluate the mechanisms of spinal cord injury models. It adopts an accurate laser to achieve the precise location and measurement. Used with the rat and mouse adaptor or the monkey adaptor, the spinal impactor solves the problem of modeling error caused by spinal collapse, thus ensuring effectiveness and uniformity during experiments.

Benefits:

  • New design & easy operation, suitable for mouse, rat, or monkey within 5 kg, such as the Macaca Fascicularis.
  • Pneumatic control of speed, depth, and dwell time.
  • Specialized laser sensor to ensure accurate measurement, with 0.01mm accuracy.
  • Speed, dwell time and displacement graph can be displayed and recorded on a PC through software.
  • Data can be recalled at any time to review an experiment. High reliability due to better simulation trauma biomechanics characteristics.
  • Cylindrical flat hammer, OD 3 mm, can be dismounted.
  • Speed 0.00~2.00m/s, depth 0.00~10.00mm, dwell time 0.05~5.00s.
  • The spinal cord adapter holds the spinal cord from bilateral processus transversus, avoiding depth measurement error due to animals breathing; also avoids subsidence of the spinal cord on impact.
  • Windows XP, 7,8,10 compatible; computer not included.
