Programmable Gas Flow Controller – LAMBDA MASSFLOW<\/h2>\n

The LAMBDA MASSFLOW is a new mass flow controller system especially designed for use with LAMBDA laboratory bioreactors and fermentors. For example, it allows\u00a0control of the pH of a cell culture<\/strong>\u00a0by the controlled addition of gaseous CO2<\/sub>, the\u00a0control of dissolved oxygen<\/strong>\u00a0by regulation of the airflow or any other gas with a suitable controller. However, it\u00a0can also be used independently<\/strong>, since all its functions can be controlled from the front panel of the MASSFLOW.<\/p>\n

The flow rate is measured by\u00a0high quality laminar mass flow sensor<\/strong>\u00a0tubes and is displayed on a digital display. The mass flow cell has a very low-pressure drop (less than 1 cm of H2<\/sub>O) and a linearity error of less than \u00b13% reading (which is much better than the precision expressed as a percentage of full scale used by some manufacturers). The repeatability is better than \u00b10.5% reading. The flow rate is regulated by a specially developed\u00a0proportional needle valve controlled by a microprocessor<\/strong>.<\/p>\n

MASSFLOW can be operated manually with the buttons on the front panel or using the remote control. The analogical remote control includes ON\/OFF and 0 to 10 V full-scale control of the flow rate. Digital control can be achieved by the optional RS-485 interface.<\/p>\n

Programming:<\/strong><\/h3>\n

Up to 50 pairs of flow rates and times can be programmed. This allows the flow to be switched on and off or the setting of any flow rate for a desired time interval.<\/p>\n

Gas volume totaliser:<\/strong><\/h3>\n

MASSFLOW generates impulsions after every 5 ml of gas flow. These impulsions can be totalled LAMBDA INTEGRATOR (Art. No.: 4803), measured as a voltage, recorded on a recorder or on a PC (e.g. fermentation program FNet or SIAM). In this way exact volume information can be obtained.<\/p>\n

Zero setting:<\/strong><\/h3>\n

MASSFLOW is equipped with an automatic zero setting which further improves the precision of the flow rate reading. This function allows precise calibration when other gases are used.<\/p>\n

MINI-4-GAS:<\/strong><\/h3>\n

LAMBDA offers\u00a0MINI-4-GAS, an\u00a0automatically controlled gas mixing module<\/strong>\u00a0for MINIFOR bioreactor and fermentor to maintain the optimal physiologic conditions of your mammalian and stem cell cultures using modern control strategies.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
