Micro Pressure Measurement Update

New Generation Fiber-Optic Pressure Measurement Systems

GOLETA, CA--(Marketwire - August 23, 2007) - BIOPAC Systems, Inc. -- worldwide distributor for Samba Sensors AB, Sweden -- introduces new generation fiber-optic pressure measurement systems using ultra-miniature sensors. Systems are available for pressure measurement on one channel (BIOPAC MPMS100A-1, Samba 201) or two channels (BIOPAC MPMS100A-2, Samba 202). The new systems are stand-alone devices developed for high precision pressure monitoring, and easily interface with BIOPAC MP150/MP100 data acquisition systems and amplifiers for comprehensive physiological research, with a primary use in life science applications.

The new micro pressure measurement system with the ultra-miniature Samba Preclin™ transducer (BIOPAC TSD170 series) is particularly useful for cardiovascular studies, e.g. to monitor real-time intravascular blood pressure (IBP), left ventricular pressure (LVP), right ventricular pressure (RVP) and right atrial pressure (RAP) in mice and other small animals. The system's insensitivity to all forms of electro-magnetic fields offers the ability to monitor all these parameters in real time during MRI scanning.

Examples of other areas where the Samba system offers unique performance include neuro-trauma, respiratory, orthopedic, oncology and urology research.

Intelligent electronics in conjunction with fiber optics produce accurate data at high speed, making instantaneous pressure change analysis possible. New features include:

--  Two ultra-miniature fiber-optic transducers can be connected
    simultaneously for relative pressure studies (BIOPAC TSD170, Samba
    Preclin™ series).
--  Improved pre-calibration concept -- the transducer's calibration
    information is now stored directly on its optical connector. The
    information is automatically read into the control unit at start-up. No
    further recalibration is needed.
--  Data sampling rate of up to 40 kHz offers unmatched possibilities to
    visualize detailed pressure patterns during fractions of a second, all
    within a hand-held device.
--  Size, weight, battery operation and internal data storage capacity
    make it fully portable and suitable for most research conditions, e.g.
    studies on location and in the MRI lab.
--  Interface with BIOPAC MP Research Systems or most third-party data
    acquisition systems.
--  USB 2.0 port facilitates data transfer into a computer.
