The Bellco Cell Production Roller Apparatus has been designed for production of animal cells, viruses, and cell products. Modular units are available from 5 to 45 bottle positions and allow easy expansion with modular add-on decks. Non-modular production units come in 45 and 50 bottle positions with over 80,000 cm2 of surface area. Rollers have a key design to eliminate slipping and are easily removable for servicing of bearings. Rollers are formulated from a chemical-resistant non-slip EDPM. All units feature a solid state control with heavy-duty DC motor and digital display. All Position Drives are for use with plastic roller bottles to prevent slipping of the light-weight bottles.
