DIACELL ON-LINE BIOMASS MONITOR MEASUREMENT
DIACELL, cell growth monitor is an optical transmission sensor that enables users to accurately monitor fermentation and cell culture processes directly in the reactor. The sensor design and choice of communication platforms have been designed specifically to facilitate process optimization, validation and scale-up.
The DIACELL sensor is a near-infrared light absorption sensor that comprises a sensor probe, selectable from a variety of configurations, a cable, and a transmitter. The transmitter integrates the signal processing, power conversion, 4-20 mA output signal generation, and user interface
functions. The 12,19,25 mm diameter sensors are suitable for even the smallest bench-top reactors and is available with a wide range of industry standard process connections.
The sensor an in-situ cell growth monitor offered with either a Bluetooth wireless browser-based user interface or FoundationTM Fieldbus digital communication.
The cell growth monitor allows for simple correlations to OD, MM cells/mL, etc. according to the end user’s laboratory method and individual process.
Growth curves, nutrient feed rates, phase changes and harvest cycles can all be easily optimized via the DIA-OD sensor.
A wide variety of probe lengths are offered for compatibility with different reactors including; 120 mm, 220 mm, 320 mm, and 420 mm probes length The sensor is available in two optical path lengths that cover any bioprocess application: 5 mm for bacterial or fermentation applications, and 10 mm for mammalian, plant, and insect cultures
DIACELL sensors are FDA approved.
DIACELL sensors are supplied with a Transmitter weatherproof, corrosion resistant enclosure. The panel mount version fits standard ½ DIN panel, and its suited for easy mounting in cabinettype enclosures. A pipe mounting accessory kit is available for mounting to pipe lines. There are two levels of access (operator and technician). The access level setting determines whether both, neither, or only the technician level require using a password to log into the transmitter.
Only the technician level has access to setup menus. The transmitter offers automatic recognition of up to twelve (12) probes, and stores the initial calibration data for each probe. Diagnostics such as the “laser test” or “probe health test” warn the user of an aging or failed probe. All transmitter and probe configuration settings are recovered automatically from non-volatile EEPROM when power is restored after a power failure.
