BIOPHYSICAL INSTRUMENTATION

Products

Signal Acquisition

The IDAC (Intelligent Data Acquisition Controller) systems are software controlled signal acquisition systems containing programmable amplifiers and filters, optimised for EAG, SSR, and GC-EAD/SSR recording.

Manipulators

Manipulators are necessary for making contact with small and delicate preparations. Different versions are available. From relatively simple systems to record from an insect antenna (EAG) to very delicate and high precision motorized systems to record from individual sensillae.

Probes

Headstages and probes are the interfaces between the signal source (insect preparation) and the IDAC acquisition system. The probes can be connected directly to the input of an IDAC system.

Stimulus controllers

Stimulus Controller CS 55 with built-in air pumps. Suitable for EAG and GC/EAD and SSR. Including foot operated start switch. Delivers continuous and pulsed air flow. Graphic LCD display.

More…

Taste probe

The Taste probe DTP-02, is a further development of the special amplifier that permits reliable DC recordings from insect taste receptors using the Hodgson (1955) technique.

More…

Electrode etching

Compact device with built-in power supply and adjustable output voltage 1 – 12 V. Electrode clamp on vertical positioner and adjustable clamp for carbon electrode and glass solution vial.

More…

Signal stimulator

This device tests the complete recording system. It simulates a 1 mV EAG response as well as spike signals from Single Sensillum Recordings (SSR).

More…

Locomotion compensation

The SYNTECH ServoSphere is functionally similar to the locomotion compensator for insects first constructed and described by Kramer (1976).

More…

GC-EAD

In applications as GC-EAD and GC-SSR  recordings an antenna or Single Sensilum acts as a detector for active fractions in the effluent of a gas chromatograph (GC). This requires a suitable effluent splitter to be installed in the GC to apply part of the effluent to the insect preparation.

Probe Amp

This device has been developed to combine a GC/MS system with a EAG recording unit.
