JMAR Technologies Releases BioSentry Designed for High-Purity Water Applications

New System to Be Tested in Pharmaceutical Manufacturing
Application
SAN DIEGO--(Business Wire)--JMAR Technologies, Inc. (OTCBB:JMAR), a leading developer of
advanced laser, photonics and detection technologies, today announced
a new release of its flagship sensor product, the BioSentry(TM), which
has been engineered specifically for use in pharmaceutical
manufacturing and other high-purity water applications.

BioSentry(TM) is a water monitoring system that provides early
contamination warning from waterborne microorganisms. Whereas current
water monitoring depends on grab sampling of water and time-consuming
lab analysis, BioSentry uses laser-based technology to provide
continuous, on-line, real-time monitoring of harmful bacteria.
Initially, BioSentry targeted applications in homeland security, the
beverage industry, and municipal drinking water utilities. With recent
system enhancements, the BioSentry can now meet the stringent
requirements of high-purity water applications in such industries as
pharmaceutical, personal health care and semiconductor manufacturing.

Upgrades to the BioSentry include:

-- High temperature compatibility for water for injection (WFI)
and sanitation requirements

-- Use of pharmaceutical-grade materials including a 316L
stainless steel flow cell

-- Automatic flow control

-- Auto-sanitization

The new system is currently being installed for testing at a major
U.S. pharmaceutical company as part of their Process Analytical
Technology (PAT) program. PAT is a system for designing, analyzing,
and controlling manufacturing through timely measurements of critical
quality and performance attributes of in-process materials with the
goal of ensuring final product quality(1).

Commenting on the new product enhancements, David McCarty, Vice
President for JMAR's Sensor Products Group, stated, "The new release
of the BioSentry is a major milestone in our product development. Not
only have we broadened the scope of markets and applications we can
now address, but our core system has evolved to be more robust and
easier to maintain."

"These developments in the BioSentry product line are evidence of
JMAR's determination and ability to design and deploy
application-specific solutions," said Dr. Neil Beer, President and CEO
of JMAR. "I believe acceptance of the BioSentry in the pharmaceutical
industry will open doors to a host of high-purity water applications,
resulting in increased sales and greater market penetration."
