The proBE 3000 micro sensor employs a near infrared laser  to determine on-line, real time biomass in fermentors from 0.01 to 200 g/L dry cell weight, without dilution, without sampling, with one single sensor.

The required measurement volume is small enough so that measurements can be made in small vessels and large vessels while at the same time maintaining a very wide linear range of sensitivity to biomass (over 4 orders of magnitude).

• Capable of working with the smallest of vessels including 125 mL and smaller
• Requires only 3 cm's of culture media to measure
• Effective bubble discrimination in high aeration and agitation environments
• 4 orders of magnitude with one sensor
• Measures less than .01 to over 200 g/L DCW
• Available in 3.2 and 4.0 mm's diameter
• Sensor for 12 mm port coming soon
