  Working Principles
Click to ViewElectrophysiological response recording. Electro physiological response of insect antennae can be record for various chemical compounds .

  User Instructions
The instrument could be use in discovery of chemical molecule responsible for insect attraction, aggregation, repellence and insect ecological behaviour. 1.The insect specimens should be alive and active for next preparations. 2.Antennae need to be cut as per desired experimental aim. 3.The cut antennae need to be fixed on the wire electrode using the conductive gel 4.The probe to be fixed to the micromanipulator and the allowed to stabilize for few minutes. 5.The chemical compound eluted from GC column is allowed to flow on to antennae for recording electrophysiological response via recording program.
