Rapid detection

Rapid detection

Panasonic's unique bacteria detection technology "DEPIM" yields results that correlate closely with a conventional culture method in approximately one minute.

What is DEPIM?

DEPIM (DiElectroPhoretic Impedance Measurement) is a method that uses a microelectrode chip on which bacteria in liquids are captured by dielectrophoresis (DEP) and measures impedance change, which is then converted to bacterial concentration per mL of sample (cfu/mL).

High accuracy

Evidence shows that the results obtained with DEPIM closely correlate with those of a culture method for detection of oral bacteria.

Correlation with culture method

Easy to use

Anyone can easily operate this device in a variety of settings due to its compact size.
