The SPP-100 Extracellular AC Amplifier/Filter is a standalone alternative to our modular NeuroLog System AC amplifier and filter modules, which have been used for electrophysiological research and teaching applications for many decades. Facilitating low noise, AC-coupled, differential electrophysiological recordings from animal or in vitro preparations, via gross electrodes such as wire hooks, glass pipettes or metal microelectrodes, the SPP-100 incorporates a gain of up to x20k with built-in high-cut, low-cut and 50/60Hz notch filters. The SPP-100 amplifier system comprises a compact main amplifier unit, remote preamplifier headstage suitable for micromanipulator mounting, an external DC power supply and a headstage accessory kit. The SPP-100 has an analogue voltage signal output, compatible with third-party DAQ hardware and software providers.
Compact Low Noise Preamplifier Headstage
The preamplifier headstage features a removable rod for micromanipulator mounting and input sockets for connection to the +INP electrode (2mm), -INP reference (inverting) electrode (1mm) and COM/Ground (1mm). The supplied headstage accessory kit includes connectors for these three inputs and a “U”-shaped jumper that allows linking of the –INP and COM inputs when single-ended recordings are being made. The SPP-100-HS headstage is compatible with our NL04/NL08 tungsten microelectrode holders and glass microelectrode holders (NL111) which are available to purchase from Digitimer.
Portable & Easy to Use Main Amplifier/Filter Unit
The SPP-100 main amplifier/filter unit incorporates an external power supply input socket, a 4-pole headstage connection socket and a BNC connector for the amplified analogue signal output. There are five controls, a single multi-function rotary encoder/button, and four further push buttons. Gain and filter settings are displayed on an adjustable brightness color LCD screen. The main amplifier unit includes two fold-out feet that offer an alternative viewing angle.
