Overview
The VWR Nutating Mixer is a three dimensional shaker typically used for maintaining the uniform suspension
of blood components in blood collection tubes without foaming. The VWR Nutating Mixer is also ideal for
mixing large strands of DNA into solution in micro tubes or mixing blood into a buffer in large centrifuge tubes.
The Nutating mixer achieves it's 3-dimensional mixing by combining the rotating motion of an orbital shaker
with the rocking motion of a platform rocker.
The modern styling of the VWR Nutating Mixer's housing is achieved through the use of injection molded FR-
ABS plastic. The large platform is constructed of powder coated aluminum toped with a rubber TPE mat.
Installation
The VWR Nutating Mixer can be used on a bench, in a cold room or in an incubator up to 40C. Place the unit
on a flat stable surface and be sure to leave sufficient room around the unit to allow both the platform and load
to move freely. A minimum of 4 inches (10cm) clearance on all sides of the mixer is advised.
Plug the unit into a properly grounded outlet of the appropriate voltage as shown on the units data plate label.
Operation
Tubes may be placed directly on to the dimpled mat. The dimple pattern is configured to allow blood tubes and
centrifuge tubes to be securely placed on the mat without additional strapping in most cases. If tubes are to
be stacked, they should be secured with rubber bands or bungie cords. Holes in the corners of the platform
edges are provided for this purpose.
Always load the platform in a uniform and balanced fashion.
!
Use the On / Off switch to turn the unit on. The direction of rotation in which the unit starts is random and does
not affect mixing. If desired, the rotational direction can be reversed by holding the unit's base and very briefly
touching the rotating platform on the bottom at one corner. This technique can also be used to select the
quietest direction of rotation.
Maintenance
Always disconnect cord from power source before maintaining or servicing.
!
The VWR Nutating Mixer requires no maintenance other than occasional cleaning with a damp cloth with mild
detergent. The rubber dimpled mat may be washed in soap and water. Do not immerse the unit in water or
spill liquids over the unit. Be sure the unit is dry before reconnecting to power.
Service & Repair
The VWR Nutating Mixer is a well built unit that should provide years of trouble free service. Should service be
needed, contact your local representative or visit vwr.com. Service should only be performed by a qualified
service technician.
