Product Overview

Startle Reflex System - the world’s most widely used startle system and by far the best for testing startle habituation and pre-pulse inhibition. The basic SR-LAB hardware and the Microsoft® Windows-based software put all startle paradigms into your hands. Virtually any combination of tones, noise bursts, lights, air puffs, background noise and foot shock options are controlled by the SR-LAB software.

SR-LAB supports up to sixteen test stations. Four standard sizes of animal enclosures can be ordered with the system. Custom sizes are also available upon request. The test cabinets allow full and unobtrusive observation of test animals in their enclosures. The animal enclosures are removable for easy cleaning. Data collected by the SR-LAB are completely secure and recorded in a non-editable form. The SR-LAB is available in three configurations: the ‘ABS’, ‘Prime’ and ‘Starter’ systems.

SR-HLAB (Formerly EMG-SR)

SR-HLAB System – for clinical or primate research from the designers of the world’s most widely used startle system.

Product Overview

The SR-HLAB Response Module is contained in a portable chassis and includes response amplification, filter and isolation circuits. The basic chassis may contain up to two response amplifiers. An optional 'daughter' chassis enables the Response Module to expand to eight amplifiers. For the EMG Electrode method the amplifier includes both + and - electrode inputs, multiple, selectable noise band filters with over 100dB common mode rejection at 50Hz for export. Discrete, selectable amplification levels are available with 50 microvolt full scale sensitivity. For the photoelectric cell (PEC) method the amplifier records eyelid movement. Lid closure reflects an LED ray back to an adjacent photoelectric cell; milli. volt output increases with blink initiation, decreases with blink completion, and a waveform is produced. Subject isolation is designed to meet ANSI/AAMI standards.

Gemini Avoidance System

Product Overview

SDI’s Gemini™ Avoidance System is designed for active and passive avoidance testing in rats and mice. It can be configured with up to 8 test stations with each station starting and running independently. A Gemini test station is a two-compartment enclosure with an interchangeable rat or mouse grid floor (conversion takes less than five minutes), 16 photo-beams for precise location of the animal, two, house, and two, cue, lights, two sound generators and an SDI Animal Shocker. SDI’s Animal Shocker is the only one of its kind to display the actual current being administered to the subject. Photo-beams may be manually disabled to vary the required compartment entry distance.

Gemini’s easy to use menu-based software offers passive avoidance (Classic and Trials to Criterion) and active avoidance options, full test diagnostics, runtime data display and a fully formatted report. Gemini’s standard data file can be transferred into other data management or statistical programs.
