-Companies to Investigate Development of Another Novel Microfluidic System-

HERCULES, Calif. and HOPKINTON, Mass.– Bio-Rad Laboratories, Inc. (Amex: BIO and BIOb) and Caliper Life Sciences, Inc. (Nasdaq: CALP) today announced a new collaboration, under which the companies will study the feasibility of developing a new microfluidics system platform. Details of the new product concept are not being disclosed at this time.

The two companies’ previous collaboration, initiated in mid-2003, resulted in the successful launch of a new microfluidics-based electrophoresis product, Experion, in the fall of 2004.

“The success we’ve enjoyed with the ExperionTM Automated Electrophoresis System has confirmed our belief that microfluidics is a key strategic technology,” commented Norman Schwartz, president and CEO at Bio-Rad. “After our first positive experience collaborating with Caliper, we are looking forward to this next collaboration where we will pursue new ideas regarding LabChip microfluidics as the foundation for innovative new products.”

Kevin Hrusovsky, Caliper’s president and CEO, also commented, “Bio-Rad is a model partner for our ‘Caliper Driven’ program, under which we enable life science companies like Bio-Rad to tap into our innovative technologies, expertise and patent portfolio. Their strong reputation in life sciences and diagnostics, and their well-established global distribution very effectively leverage our technology into key markets.”
