What is the Bio Disc?- The Best Detecting Tool of Biomolecules

Bio Disc could be a sensitive and high-speed analog sensor of biomolecules. It can be function as inexpensive diagnostic tools for protein detection. Because the concentration of certain proteins in the bloodstream can indicate the onset of many diseases, a cheap and fast method of detecting these biological molecules would be a welcome addition to any doctor's office. The Bio Disc could provide hospitals with a fast, easy way to monitor patient health.

How to Use?
All microfluidic elements and functions are integrated in a toolbox approach in the Bio Disc. You can explore advanced proprietary microfluidics to perform all the required steps for any diagnostic test: allowing samples to be prepared, suspended or modified as required, suspension of reagents,mixing and fluid delivery to detection areas. This is all integrated inside a plastic Bio Disc and operated by a simple rotation protocol using a standard disc drive.





LIGA Like Technology

Using Bio Disc rather than other nascent detection technology, such as biochips, would be in the number of molecules the disks could screen for, as well as simplicity and price.

RITEK use sophisticated manufacturing techniques and quality management systems designed to ensure the highest possible level of consistency – to help give you and your customers confidence in the accuracy of their test results.


Whatever your special design, RITEK will have experience for your requirement.
