A Simple Method for Making a Vibrating Probe System
Biological Institute, Faculty of Science, Tohoku University Sendai 980, Japan
A simple and easy method for making the vibrating probe system first developed by Jaffe and Nuccitelli [(1974) J. Cell Biol. 63: 614] is described. The best performance of the probe in sea water was 30.7 µA cm-2 per one µV output, 0.4 µA cm-2 peak-to-peak output-noise and negligible output-drift at 30-µm vibrating amplitude and 3-s amplifier time constant. Sample applications were made for both freshwater and marine algae.
