With the Sciospec MEArack you get a simple and proven solution for tackling these measurements without any awkward self made cabling setups, labor intensive manual channel switching or complicated third party multiplexer integrations on top of a home cooked chip adapter… With the ExtensionPort system the MEArack just plugs into compatible impedance analyzers like the ISX-3 and you´re good to go – it´s that easy

key facts

  • adapter for multi-electrode-arrays (MEAs) and other sensors-/biochips industry standard format
  • compatible with a range of Sciospec products from multiplexers and impedance analyzers all the way to the EPIX platform
  • layout fitting broad range of industry standard sensors
  • optional custom chip development
  • small form factor, low profile
  • bottom and top windows for use in combination with microscopes
  • via cable or directly inserted in the instrument – with SC98 all options are valid

With the SC98 connectivity the MEArack just plugs into any compatible multiplexer or analyzer. Plug in and you´re good to go - it´s that easy.

In combination with our multiplexers: Any to any port assignments – nothing is impossible!

Did you ever find yourself in a situation where you had to solve the puzzle of assigning your sensor ports to a multichannel device but kept running into constraints? Maybe you even resolved to manually reconfiguring cables in between measurements to cope with this? Good news: These times are over! Freeing you of all channel assignment constraints as seen in conventional multiplexer arrangements, our any-to-any multiplexers give you complete freedom and take out the hassle and riddling of the port assignment and configuration process. Assigning ports becomes a breeze! Additionally, this opens up a world of new possibilities: switching polarities on ports, moving current paths on fixed sensing positions, fixed excitation points and scanned potential or impedance mapping, multiport component analysis, or anything else you can imagine. These multiplexers can do it. EIT style injection patterns are just as easily realized and combined with the EIT measurement option in our impedance analyzers you can do image reconstruction on top of your data.

sensor and chip types

  • industry standard electrodes/sensors available from several manufacturers
  • tons of electrode geometries and materials to choose from
  • custom made electrode structures to perfectly fit your needs
  • optional integration of fluidic handling or temperature control

Just as important as the correct instrument is the sensor type you use. The MEArack is compatible with industry standard chips available from several manufacturers world wide. Typical sensor geometries range from simple spot electrodes, over interdigitated electrodes (IDEs) up to highly specialized electrodes for specific cell cultures and experiment types.

Need something more tailored towards your needs? We can help you design and manufacture your own sensor structures specifically targeting your application. Integration of fluidic handling and temperature control is also available.

Comparison of LCR meters vs impedance analyzers

Both, impedance analysers and LCR meters are instruments for performing electrical measurements. LCR meters’ purpose is the characterization of electrical components in terms of their inductance, resistance and capacitance or other equivalent circuit models. Impedance analyzers’ scope is a lot broader than that. Measuring the complex impedance over a broad range of frequencies they can be used for all kinds of applications where determining electrical properties is crucial – e.g. material science, medical, bioanalytical, etc. However, when it comes to characterizing electrical components both impedance analyzers and LCR meters can be a valid choice. Not always an easy choice, as with highly capable modern instruments the lines sometimes get blurred. So, let’s look at some of the key things to look out for when comparing these two instrument classes.
