› Beware of hazards due to:
- flammable materials,
- combustible media with a low boiling temperature,
- glass breakage,
- incorrect container size,
- overfilling of media,
- unsafe condition of container.
› Process pathogenic materials only in closed vessels under a suitable fume hood.
Caution!
› In unsupervised and safe operation, this device may only handle or heat media whose flash
point is above the set safety temperature limit. The safety temperature limit must always be
set to at least 25 °C lower than the flash point of the media used. (acc. to EN 61010-2-010)
› The heating plate can heat up due to the action of the magnets at high motor speeds, even
if the heater is switched off.
› Please consider any possible contaminations and unwanted chemical reactions.
› It may be possible for wear debris from rotating accessory parts to reach the material being
processed.
› When using PTFE-coated magnetic bars, the following has to be noted: Chemical reactions
of PTFE occur in contact with molten or solute alkali metals and alkaline earth metals, as well
as with fine powders of metals in groups 2 and 3 of the periodic system at temperatures
above 300 °C – 400 °C. Only elementary fluorine, chlorotrifluoride and alkali metals attack
it; halogenated hydrocarbons have a reversible swelling effect.

/// Procedures during sample runs
Caution!
› Wear your personal protective equipment in accordance with the hazard category of the
media to be processed. There may be a risk from:
- splashing and evaporation of liquids,
- ejection of parts,
- release of toxic or combustible gases.
› Reduce speed if:
- medium splashes out of vessel because the speed is too high,
- device is not running smoothly,
- container moves on the base plate,
- an error message is displayed.
/// Accessories
› Safe operation is guaranteed only with the use of original IKA accessories.
› Ensure that the external temperature sensor is inserted into the medium to a depth of at
least 20 mm when connected.
› Always disconnect the plug before attaching accessories.
› Accessories must be securely attached to the device and cannot come off by themselves. The
centre of gravity of the assembly must lie within the surface on which it is set up.
› Observe the operating instructions of the accessories.
