• Widest linear range – from <0.1 to >300 OD units – of any biomass monitor
• Automated, continuous, real-time, online OD measurements
• Measures through fermentor wall or viewing port – attaches to outside of vessel
• Works well for both fermentation and cell culture
• No immersion port required – avoids fouling and contamination
• Lowest total cost of ownership of any biomass monitor currently available
Noninvasive Biomass Monitor
The BE2100 is an industry-leading, noninvasive biomass monitoring system designed for
use in both research laboratory and industrial environments. The sensor is easily secured
to the outside of a variety of different fermentor types, from small glass vessels to large
stainless steel vessels with glass viewing ports. Since no immersion port is required, the
need for sensor sterilization is also eliminated.
Real-time, Online Monitoring
The BE2100 Biomass Monitoring System consists of a sensor that attaches to a fermentor
or bioreactor, and one of three options to control the sensor: a BE2100 base unit (single
sensor), a multiplexing BE2100 Base Unit (up to 4 sensors), or the BE|USB (direct USB
adapter for single sensor), all of which interface with the included software, providing the
user intuitive controls and the ability to track the progress of fermentation in real time.
The software can calibrate the sensor output to any desired units (OD, g/L, cells/mL, etc.)
as well as track important events during the fermentation. The BE2100 and BE2400 base
units comes equipped with serial RS-232, USB and 4-20 mA analog outputs and can
function as a stand-alone device or can be controlled through software via RS-232 or USB,
enabling straightforward integration into a fermentor control system.
Ultra-Wide Linear Range
Most immersion probe methods are limited in the range of biomass growth they measure.
The BE2100 sensor on the other hand employs a novel method of optical monitoring that
responds linearly to biomass over a very wide range of growth: from less than 0.1 to
greater than 300 OD units.
