LPF-8 8 Pole Bessel Filter for Planar Lipid Bilayer Workstation
The LPF-8 is the premier low-pass Bessel filter from Warner Instruments and provides superior control of analog signal filtering. The instrument incorporates low-pass signal filtering and output gains from 1 to 200. Selectable dual signal inputs allow the instrument to be configured to operate in normal, inverted or differential modes.
This instrument features optically encoded circuitry which permits frequency selection with a single control. Since the set frequency control is not a physical part of the filtering circuit, adjustments to the instrument do not introduce noise artifacts into the output signal. This unique design uses no mechanical switching and ensures long term instrument reliability.
