A sample of our products are shown below.


Startle Reflex Package

Startle Reflex PackagePictured is similar to what one would receive with a starter Acoustic Startle Package (MED-ASR-PRO). The only difference between this and a starter package is in the bottom rack mount chassis. Pictured is a ANL-925 Audio Generator with four ANL-925B Acoustic Chamber Interface Modules. A starter package would contain only one ANL-925B module.

Several new and improved features highlight the latest Startle Reflex packages from MED Associates Inc. New is the Pro series of PPI (pre-pulse inhibition) and FPS (fear potentiated startle) software. These user friendly applications were designed by Dr. William Falls of the University of Vermont to go from one step user input to data output. Another software/hardware package as part of the first test station is the MED-ASR-SPL Sound Pressure Level Measurement Package for precise stimulus calibration at intensities never covered by hand-held sound-level meters. This is especially critical for work with mice. Finally, the new test station includes components for standardizing the position of the stimulus speaker and animal platform while at the same time providing a balanced stimulus output.

Operant Test Chambers

Modular Operant Test Chamber with Modified Top

Operant Test ChambersThis unit is the preferred unit for rodent studies using drug self administration. The working height has been reduced to 8 ¼" (21 cm) to allow sufficient space for a drug delivery swivel and counter balance arm when placed in a sound attenuating cubicle. The top has been modified by adding a 2" (5.1cm) diameter hole in the center of the top with a ¼" (6.4mm) access slot cut from the hole to the front edge. This permits the user to place an animal in the test chamber with a drug delivery leash or other harness system attached. All other features of this chamber are identical to the ENV-007 Modular Test Chamber.

Videotrack System

Automated analysis system for behavioural studies on rats and mice

Test performed with the VIDEOTRACK system


The system easily automates most tests based on locomotive activity:

  • Open field in standard lighting, infra red
  • Radial Mazes
  • Plus Elevated Maze
  • Stairs
  • Place Preference
  • E water Maze
  • Multiple T Maze
  • Black on White box
  • Water mazes (MORRIS water maze)

With the use of cameras sensitive to near infra-red, you may also consider applications in Chronobiology or Actimetry in conditions of light and pseudo-darkness over long periods of time.

Open Field Activity

Open Field ActivitySelect from two standard field sizes or contact us for custom made units.

  • Additional test stations are easily attached to the network and to the power supply.
  • Standard data elements include times resting, ambulatory, rearing, and stereotypic, incremental counts for appropriate measure, and distance travelled.
  • Measurements may be taken in a continuous test session or as small samples repeated at a preset interval.
  • All components available individually to meet custom applications.
Stereotaxic Instrument

Stereotaxic InstrumentThe MM Stereotaxic instrument, used on small animals, is derived from the M medical device series.

For a higher accessibility to the operating area, the device is equipped with a vertical axis for complete rotation.

  • Extended bars and forks can be added to operate on the spinal cord.

The incisor bar can be moved to ease the use of non standard Atlas. The system is therefore raised to provide greater accessibility when placing the animal.

The above products are a sample of the equipment that we sell. Also included in our portfolio are:

  • Startle system
