Electrical impedance spectroscopy package
A complete system to start EIS experiments
Electrical impedance spectroscopy (EIS) is a technique that guarantees fast throughput and label-free sensing so that it can be used to characterize electrical properties, size, or morphology of cells in microfluidic devices. Fluigent and Zurich Instruments drew on their expertise to propose a complete solution for EIS in microfluidics.
- Save time
Wide range of analysis tools
Small sample volumes
Good integration with other analysis methods (e.g. optical detection), the EIS instruments allow for simultaneous multi-frequency measurement.
With this package, you have all the fluidic components necessary to start EIS experiments.
We built the package with the right pressure controllers, microfluidic chips.
We can adapt the package to fulfill your needs.
The microfluidic EIS technique involves monitoring the change in the frequency-dependent dielectric properties of the channel as the cell passes through it. The measurement requires both high sensitivity and fast response.
As the analyte enters and exits the differential electrode pairs in a microfluidic chip, a peak and a trough in current are observed. With a differential input, the signal from the surrounding fluid is suppressed, meaning each cytometry event can be resolved with reduced noise.
The importance of pressure-based flow control
Control flow rate with the benefits of responsive, pulse free flow
Pulse-free flow is critical for generating high quality and repeatable results. The Flow EZ™ integrates the all-new DFC (Direct Flow Control) algorithm which allows the user to set a flow rate directly on the instrument display. The applied pressure will automatically adjust to maintain the flow rate.
A response time ten times faster compared to mechanical solutions
With the use of pressure instead of mechanical action, the Flow EZTM gets responsiveness ten times faster than syringe pumps. A low response time allows one to quickly execute operations such as stop flow and pressure/flow rate steps.
