Taste Probe DTP-02
The SYNTECH Tasteprobe, Type DTP-02, is the latest development based on the special amplifier described by Marion-Poll and Van der Pers (1996) that permits reliable DC recordings from insect taste receptors using the Hodgson (1955) technique. The present model can operate in DC or in AC mode. In DC mode the complete signal, slow (DC) and fast (AC) fluctuations are recorded and amplified. In AC mode the slow (DC) fluctuations are out-filtered and only the fast (AC) components of the signal (like Spikes) are amplified. In both recording modes the DC initial offset at the onset of the recording (before contact is made between the recording electrode and the preparation) is cancelled automatically.
