Amplifier
Designed for in vivo multi-channel recording, our headstages in combination with pre- or filter-amplifiers, together with MC_Card and MC_Rack, offer unsurpassed performance up to 128 channels at a sampling rate of 50 kHz/channel. The 8-channel headstage HA-8 is small but sturdy, easily being fitted onto swifels for freely moving animals, and can be combined in multiples of 64 channels per cube. One cube (or two for 128 channels) is then relayed via a switch box and a 68-pin SCSII-cable to the MC_Card data acquisition board. We do offer custom-based connections between various microwire-electrodes and our HA-8 headstage. Our philosophy is to keep our amplifiers compact, reliable, and state-of-the-art. Modern real-time digital signal processing eliminates the need to make the parameters of filter amplifiers adjustable. This surely is a shift from today's practice. Imagine you are interested in measuring slow field potentials, and in a slightly different experiment on the same specimen, you focus on high-frequency spikes. In both cases you can work with the same high-quality broadband amplifier, and digitally filter out the interesting frequency ranges. You can even obtain both frequency bands simultaneously in a single measurement. Changing the types and characteristics of the digital filters can be done without danger of distorting or even deteriorating your signals. Thus our filter amplifiers are designed to do this job extremely well: Amplify your signals, and restrict them to a sharply defined frequency band. This approach helps you to keep your experimental setup easy, reliable, and reproducible. We offer a large selection of high-end pre- and filter-amplifiers, from 8 to 128 channels, with differential and single-ended inputs, and a wide range of gains and frequency bands. Take full advantage of the compactness, reliability, and ease of handling of our amplifiers for fast and reproducible experimental setup. Small amplifiers are crucial for a simple experiments.

Accessories
Multi Channel Systems offers a variety of accessories to complete the neuroscientist's' set of equipment for single and multichannel measurements. MC_Valve is a Win/PC-based software for the control of up to 8 individual valves connected to the bath perfusion. A PT-100 based temperature controlling unit is easily connected to the MEA1060 amplifier and keeps your preparation at a steady and constant temperature. In order to keep the bath perfusion solution at a constant temperature a small bath perfusion heater is available to heat the in-flow solution just prior entering the MEA chamber.
Temperature Controller
The temperature controller for physiological experiments is available as single or double controller.

Perfusion Heating
In order to keep the bath perfusion solution at a constant temperature a small bath perfusion heater is available which allows the heating of the in-flow solution just prior before entering the MEA chamber.
