The Wheaton Modular Roller Apparatus allows large-scale propagation of monolayer cell cultures in standard glass and plastic roller bottles. Extra decks can be added to existing units as modular requirements expand - up to 9 decks total.

The Wheaton Modular Roller Apparatus uses a powerful DC gear motor and can accommodate bottles 108-121mm in diameter and up to 550 mm in length, with a bottle speed range of 0.25 to 5.3 RPM assuming 110mm bottles.

If short roller bottles are utilized, twice as many bottles may be placed on the apparatus. To provide ease of operation, all controls are conveniently located on the front panel. A locking speed control prevents accidental changes in drive speed, while a reference meter permits replication of speed settings.

Power inlet module: Location of the line cord entry. Contains the fuse and voltage selection module.

Step Down Transformer: Steps down line voltage if 220V operation is selected.

Motor Controller Board #4: Controls the 90VDC motor. Speed is set by turning the adjustment knob.

Motor: Turns all the rollers of the rack via two main belt trains running down the back of the roller rack.
