SEC series systems are versatile intracellular recording systems. SEC systems are the fastest and most accurate single-electrode current - and voltage - clamp systems available.
These amplifiers are suitable for recordings with high resistance microelectrodes, for tight-seal perforated patch, or whole-cell recording techniques. They also allow intracellular recordings during in vivo voltammetry experiments. Currently, SEC amplifiers are used in vertebrate (rat, mouse, cat, fish etc.) and invertebrate (leech, crab, snail, insect etc.) neurons, muscle cells, other excitable tissue and plant cells.
A significant improvement over other time-sharing amplifiers is that the SEC systems fully compensate the recording microelectrode. This allows single electrode recordings with the same accuracy and speed of response as with the standard two electrode voltage clamp approach.
All systems include four (optionally eight) modes of operation, many automatic functions, protection circuits, versatile I/O signal conditioning units, and digitally controlled operation. All of these features make these amplifiers the ideal research instruments for all electrophysiological investigations using intracellular microelectrodes or suction electrodes (patch pipettes).
NEW: All SEC amplifiers are available with LINEAR MODE for low-noise recording of small currents with patch pipettes. It also allows loose-patch or macro-patch recordings, and can be used to approach the cell and form a gigaseal in VC mode.
The linear mode includes now also a switch that enhances the current and voltage range ten times. Therefore, the amplifiers can also be used for non-invasive filling of cells with dyes or single cell transfection with DNA .
Existing SEC amplifiers can be upgraded to linear mode. Please contact npi electronic for details.
SEC systems also available as modules for the EPMS-07 system. The combination of two or more SEC modules results in a convenient instrument for recording in coupled cells.
