Overview

High density Microelectrode Array with large sensing area

HD-MEA probes integrate 4096 low-noise electrodes that can be recorded simultaneously.

Your best research partner

Cellular networks often require time, expertise and endeavour to obtain the performance required to validate your research hypothesis. You deserve a proper technology partner to ensure you miss neither cell signals nor network richness.

HD-MEA probes provide access to the finest details in cellular network activity for both neuronal and cardiac preparations.

The dimension, distance and spatial arrangement of the electrodes over large areas have been specifically designed to allow you to grasp as much detail as possible, without losing sight of the big picture in your network dynamics.

Different MEA chip models are available to match your experimental needs in terms of resolution, field of view and stimulation capabilities.

HD-MEA Prime

Designed for cell cultures

Prime is a microelectrode array integrating 4096 recording electrodes on a small and compact area of 2.67mm x 2.67mm, centred in a flat area of ~3mm x 3mm. This arrangement is ideal to reduce the number of seeded cells.

The electrode size is 21µm x 21µm, with a pitch of 42µm. The glass ring internal diameter is 25mm, with a height of 7mm.

HD-MEA Arena

More space to accommodate large tissues

Arena comprises the same recording array as the Prime model (4096 electrodes in a 2.67mm x 2.67mm area), but in addition it delivers a larger surrounding flat area (6mm x 6mm), which is very handy for positioning large tissues while guaranteeing an optimal coupling with the electrode array.

The electrode size is 21µm x 21µm, with a pitch of 42 µm. The glass ring internal diameter is 25mm, with a height of 7mm.

HD-MEA Stimulo

The MEA to electrically stimulate your sample

The Stimulo CMOS-MEA  has a larger sensing area (5.12mm x 5.12mm), since it delivers an increased electrode pitch of 81µm. This allows recording from large portions of neuronal tissue, while still having a high spatial resolution.

Moreover, the Stimulo model offers a secondary array for stimulation with 16 electrodes, arranged in a 4 x 4 uniform grid, that are interspersed between the recording electrodes.

The electrode size for both recording and stimulating electrodes is 21µm x 21µm. The glass ring internal diameter is 25mm, with a height of 7mm.
