Dagan FL4

FL4 Four Pole Bessel Filter (CORNERSTONE Series)

The FL4 Four Pole Bessel Filter is a general purpose, high cut(low pass) filter. It's Bessel filter characteristics are ideal for pulse-type data such as patch clamp recording. Also available: FL8 Eight Pole Bessel Filter providing the same features, with a sharper Cut-off at the selected bandwidth.

Features

12 filter settings
3 gain settings
Selectable signal coupling
Phase (polarity) inversion
Low noise, external power supply

Applications

Patch Clamp recording
Removal of background noise from pulse data
Turn-key signal conditioning
