The most sensitive and flexible medium throughput MEA system for both acute and cultured applications

MED64-Quad II system is a medium throughput MEA system both for acute and cultured applications. Extracellular signals are recorded from 4 independent Probes/Connectors, which will give high flexibility. It is a powerful solution for drug discovery screening. The MED64’s high fidelity will provide more accurate and reliable data allowing for advanced screening.

Features

Acquire extracellular signals from 4 samples (16 electrodes/sample).
Stimulation to all samples sequentially (up to 2 electrodes simultaneously) using internal stimulator.
Unrivaled signal-to-noise ratio of 0.8 μV RMS noise level.
Large current-driven stimulation via any electrode.
High-quality evoked signal without interference of stimulus artifacts.
Recording inside of a humidified incubator.
One system can be used for multiple experiments with its amplifier’s broad acquisition bandwidth and analog lowpass/highpass filter.
Analyze data online during your experiment or offline after.
Suitable for acute slices, slice cultures, and cell cultures.
Low-cost shift to MED64-Allegro/Basic System.
