2. Applications
2.1 Operator
The 100% maintenance- and wear-free magnetic stirrers MIXdrive are
used in the fields of chemistry, medicine, pharmacy, microbiology and
biotechnology.
The operators are generally working in research and development,
production and quality assurance.
2.2 Basic functions
Basic function is stirring of liquids in suitable and chemically resistible
vessels.
The stirrer housing is hermetically close and therefore immersible.
The maximum ambient temperature is +50°C in air and +50°C in water
immersed.
The maximum ambient temperature of the high temperature versions
(MIXdrive HT-series) is +200°C in air and +95°C in water immersed.
2.3 Product combinations
In addition to the use at the conventional laboratory desk our products
have also been tested for the application in
Laminar flow devices
Safety cabinets
Safety cabins
Water baths
Incubators
Please note: For using the stirrer in incubators please set the adjustable
stirring power to the minimum usable power to reduce the additional
heating effect caused by the magnetic stirring drive. Please see chapter “5
External heating operations in incubators and water baths” at page 23.
2.4 Application not for the intended use
The magnetic stirrers MIXdrive are explicitly not intended for the
application:
Stirring and warming of flammable liquids
Warming of pressure-tight closed and NOT pressure-
resistant vessels or glasses
(e.g. Erlenmeyer flasks, lab flasks)
At general atmosphere or danger of explosion

© 2mag AG Page 7 of 44 Version: 5.1
The 2mag is offering special products for the just mentioned application
combinations. More information for this can be found at www.2mag.de or
at [email protected]
2.5 Combinations of vessels
Please use round, chemical resistant and where required heat-resistant
vessels made of glass or non-magnetic metal. You can use vessels up to
the maximum size stated in the spreadsheet 1.
The vessels should have a thin, even wall thickness. Flat glass bottoms
(without any curve to the inside) and smooth surfaces will improve the
operating characteristic of the magnetic stirring bar. Uneven surfaces
would reduce the stirring power and would cause reaming up of the
stirring bar’s gliding surface.
In case you intend to stir large amount of liquids, please chose such
stirring flasks that have a comparatively small diameter and thin bottom.
The magnetic stirring bar can then be centred better.

Please always place the flasks in the magnetic
centre of the magnetic stirrer. This will ensure the
optimum stirring effect!
Do never use any pressure-tight closed flasks.
RISK OF BURSTING!
Do only use temperature-resistant vessels.
Be careful with plastic flasks!
2.6 Stirring bars
In general, all stirring bars matching the length and diameter can be used.
But we recommend using the commercial stirring bars with Samarium
Cobalt magnetic core (SmCo). By using this highly energetic magnetic
material the maximum stirring power of the magnetic stirrer can be
achieved, especially when mixing viscose media.
2.6.1 ASTEROID Stirring Bars
We recommend using 2mag –ASTEROID stirring bars to increase the
stirring performance at enhanced requirements.
ASTEROID stirring bars a newly developed, high-effective and ideal for:
large mixing volumes
viscous media
stirring over wide distances
at disadvantageous vessel bottoms.
2mag ASTEROID stirring bars transmit more than 4x higher torque.
Therefore the bars creating an unbeatable increased mixing effect in
comparison to conventional stirring bars. The high energetic and long-
term stable magnetic field does not have any demagnetization effect. The
concave design is made for a minimum of bearing surface and reliable
rotation. Significantly higher rotation speed reachable! 300% less PTFE
abrasion than comparable round shape stirring bars. The triangular shape
raises the powerful shear force and increases the mixing effect at lower
rotation speed.

© 2mag AG Page 9 of 44 Version: 5.1
The high quality PTFE cover is even and sealing the magnet, FDA-conform
and steam sterilizable at 121°C.
2.7 Tips and hints to the topic stirring
The mixing flasks should be filled max. up to the middle (high speed
range) resp. up to ¾ (low speed range).
Place one magnetic stirring bar in each stirring flask.
Place the stirring flasks right in the centre of the stirring point on the
Stirring Hotplate resp. in one borehole of the Stirring Drybath.
In case the magnetic stirring bar turns in an unsteady or jerky
way or bounces:
The interaction between the alternating magnetic field and the magnetic
stirring bar is too high.
Increase the speed or
Use a smaller magnetic stirring bar or
Decrease the stirring power.
In case the magnetic stirring bar will not be centred or leaves the
centre permanently:
The interaction between the alternating magnetic field and the magnetic
stirring bar is too low.
Or the stirring bar has a bottom that is uneven or too thick-walled.
Move the flask slightly back and fro and centre it again onto the stirring
point of the stirrer surface.
Reduce the speed or use a longer magnetic stirring bar or one with a
larger diameter or
Use a smaller flask with a thin-walled, even bottom or
Reduce the filling amount in the flasks or
Increase the stirring speed.
In case the stirring activity is too weak:
Use commercial magnetic stirring bars with SamariumCobalt-core.
Use a longer stirring bar or a stirring flask with smaller diameter.
We recommend using 2mag –ASTEROID stirring
bars to increase the stirring performance.

3. Installation
3.1 Safety advice
Please ensure the following basic conditions prior to installation:
The wear-free inductive drive works with magnetism.
Cardiac pacemakers, data storage mediums,
magnetic cards and other devices, which can be
affected by magnetic fields, have to be kept away from
the fields of the stirring unit as well as from the stirring
bars.
The device must not be used in explosive rooms.
The control unit MIXcontrol must not be dipped in water
or any cleaning solutions.
Your supply voltage has to comply with the label of the
control unit. The control unit has to be switched off
before any power connection or power disconnection.
To increase the operation safety, the control unit should
be placed apart from chemical materials and reactions
as well as away from thermal influences.
For special requirements please contact [email protected].
ATTENTION!
The control unit has to be switched off,
BEFORE you connect or disconnect the
plugs.
Always turn off the power switch first before
handling the connection cables.
