General Description
The Stuart Roller Mixers provide a gentle, but
highly efficient, rocking and rolling action. The
rollers rotate at a fixed speed of 33rpm and rise
and fall 16mm.
Most sizes of tube, Bijoux, Universals and other
bottles can be accommodated. For large capacity
bottles (up to 120mm diameter), one or more of
the rollers is easily removed, using the spanner
provided, to give improved grip. Similarly, it is
possible to quickly convert the unit to provide a
'roll only' action to function as a simple roller.
SRT1: Has 5 rollers
SRT2: Has 10 rollers
Safety Advice Before Use
❖ The unit should be carried using both hands
with fingers under each side frame.
❖ Never move or carry the unit when in use or
connected to the mains electricity supply.
❖ Do not mix flammable liquids or use the
equipment in hazardous atmospheres.
❖ In case of mains interrupting, a fault or
mechanical failure, the unit will continue to
operate on removal of fault.
❖ Mechanical energy can lead to breakage of
glass vessels. Use with care.
Operation
Position the apparatus on a firm level surface and
connect to the mains electricity supply. Place the
samples to be mixed between the rollers. Once all
the samples have been set, switch the Roller
Mixer ON using the Mains On/Off switch.
WARNING: Ensure the unit is switched
Off at the mains before altering roller
configuration.
Removing the rollers
The rollers may be removed from your unit to
accommodate larger vessels. To remove, first
loosen the two securing screws shown in figure 1
and remove the end panel.
Undo the pivot bolt of each roller to be removed
using the spanner provided. Lift the free end of
the roller and gently pull it away from the drive
unit. Keep all rollers and bolts in a safe place.
Roll only operation
Your SRT Roller Mixer is factory set for a 'rock
and roll' mixing motion. The action can be
converted to a roll only operation.
First, remove all rollers as described above. One
by one, starting at one end, replace each roller
using the CENTRIC securing hole in both the
drive and end pivots. Tighten the bolts using the
spanner provided.
Maintenance & Servicing
WARNING: Ensure the unit is
disconnected from the mains electricity
supply before attempting maintenance or
servicing.
Periodically clean the instrument using a damp
cloth and mild detergent solution. Do not use
harsh or abrasive cleaning agents.
Any repairs or replacement of parts MUST be
undertaken by suitably qualified personnel.
