Microfluidics Probes and Probe Stations
December 2011
|
Mengel Engineering now offers the new microfluidics probes and probe stations from US Company CorSolutions. The microfluidics probes provide stable, non-permanent fluidic connections to microfluidics chips made from glass, PMMA, COC and even soft materials like PDMS. The probes are used as alternative to permanent ports, bonded, heat-cured or cast onto the fluid access port. The probes consist of an all-metal precision-machined adjustment body and a compression sealed tubing/chip adapter. The adapter is pressed against the chip surface by a spring-loaded screw with a precisely adjustable force, ensuring repeatable and leak-free connection to the fluidic port. The ports are easily disengaged and re-engaged so that the chip can quickly be changed without the need for readjustment. Using the Corsolutions ports allows for rapid, nonpermanent, low or high pressure, leak-tight connections to be made to microchips in a highly reproducible manner, at any location on the microchip surface, irrespective of manufacturer-specific port pattern geometry. The system can be used for the final performance assessment of a finished microfluidic product, or for processing and analyzing samples in a microfluidic chip. A variety of tubing/chip adapters are available for different tubing sizes and different access port dimensions and materials. Unlike previous designs, the fluidic interface is a separate component attached to the port body, allowing the user to use his own design connectors.

Probe stations
The probe stations consist of a breadboard with mounting holes for probes and additional user-specific components. A microfluidic chip is mounted in a 100mm diameter chip holder, mounted in a central cutout allowing optical access from both sides. The probe stations are available as stand-alone breadboards with an optional macro- or microscope for bright-field, backlight or fluorescence imaging of flow properties. Alternatively, breadboards are available with adaptors to mount on the stage of an inverted scientific microscope. |
