SECTION 2.0 - INTRODUCTION
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 lock-
ing speed control prevents accidental changes in drive speed,
while a reference meter permits replication of speed settings.
SECTION 3.0 - GENERAL INFORMATION
This section contains a general description of the Wheaton
Modular Roller Apparatus. This section also contains instruc-
tions for initial inspection, installation and connecting the
