Mixers & Stirrers
Whether the task is dissolving a stubborn reagent or holding a suspension uniform for hours, the right stirrer turns an unpredictable step into a routine one. Mixers and stirrers span magnetic stirrers and hotplate stirrers, overhead motor driven units for viscous and large volume work, and vortex mixers for rapid tube mixing. Speed control, torque and chemical compatibility decide which tool fits which job. Machinery Masters lists mixers and stirrers from verified sellers, with new and used units side by side, direct owner contact and finance available on qualifying listings.

Mixers & Stirrers Product Types
Stirring equipment divides by how it drives the sample and the volumes it handles. The main variants in this leaf category are described below.
Magnetic stirrers
A rotating magnet spins a stir bar inside the vessel for clean, sealed mixing of low viscosity liquids. Compact and reliable, they are the default for beaker and flask work up to a few litres.
Hotplate magnetic stirrers
Combined heating and stirring dissolves solids and prepares media in one step. Temperature probes and feedback control hold solutions at setpoint during preparation.
Overhead stirrers
Motor driven units turn impellers on a shaft for viscous fluids and volumes beyond magnetic capability. High torque models handle gels, slurries and drum scale mixing.
Vortex mixers
Orbital cup action mixes tubes in seconds for resuspension and reagent blending. Touch operation and continuous modes cover single tubes and short batch work.
Homogeniser and disperser mixers
High shear rotor stator heads break down tissue, emulsify and disperse solids into liquids. They bridge simple stirring and dedicated sample disruption.

Warum Machinery Masters
Nur verifizierte Verkäufer
Jeder Verkäufer wird verifiziert, bevor auch nur ein Inserat online geht. Machinery Masters prüft außerdem die Inserate auf Richtigkeit, damit Käufer sich mit Vertrauen für hochwertige Maschinen entscheiden können.
Weltweite Reichweite
Die Inserate stammen von Verkäufern aus ganz Europa, Nordamerika und darüber hinaus. Diese Reichweite erweitert die Auswahl über jedes regionale Händlernetz hinaus und ist oft der einzige Weg, eingestellte Modelle in gutem Zustand zu finden.
Flexible Finanzierungsmöglichkeiten
Für geeignete Inserate ist eine Finanzierung über Partneranbieter möglich. Die Konditionen werden direkt auf den betreffenden Produktseiten angezeigt, sodass sich die Kosten verteilen, statt das Betriebskapital auf einen Schlag aufzuzehren.
Direkter Kontakt zum Verkäufer
Zwischen Käufer und Verkäufer steht kein Makler. Fragen Sie nach der Wartungshistorie, vereinbaren Sie Besichtigungen und verhandeln Sie direkt mit der Person, die die Maschine wirklich kennt.
Applications and Uses
Stirring and mixing supports work across the whole laboratory. Four common applications are outlined below.
Media and buffer preparation
Hotplate stirrers dissolve powders and adjust solutions during routine preparation. Reliable heating and mixing shortens a task every lab repeats daily.
Chemical synthesis and reactions
Overhead and magnetic stirrers maintain contact and temperature uniformity through reactions. Consistent agitation supports reproducible yields and endpoints.
Sample resuspension
Vortex mixers resuspend pellets and mix small volumes rapidly at the bench. Quick, thorough mixing prevents the errors that patchy resuspension introduces.
Tissue and material homogenisation
Rotor stator homogenisers disrupt tissue and disperse solids for extraction and analysis. High shear reduces samples to a workable uniform state.
Benefits from Machinery Masters
Stirring equipment gets bought in batches, and a deep category keeps the process quick.
01
Magnetic, overhead and vortex in one aisle
The full mixers and stirrers range lists inside the mixing, agitation and shaking category, from hotplate units to high torque overhead drives.
02
Instrument grade stirring at pre owned cost
A used magnetic or overhead stirrer performs indistinguishably from new for a fraction of the outlay, and listings show both together.
03
Torque and compatibility settled early
Sellers confirm speed ranges, torque and chemical resistance against your protocols before you buy. Qualifying listings carry finance for larger orders.
Frequently Asked Questions zu Mixers & Stirrers
Magnetic stirrers work well for low viscosity liquids up to a few litres, but the coupling between magnet and stir bar slips once the fluid thickens or the volume grows. Viscous suspensions, gels and large vessels need an overhead stirrer, which drives an impeller directly with far more torque. If your stir bar stops tracking the magnet or throws out of the vessel, that is the sign to move to overhead drive.
Check that the plate heats evenly and reaches setpoint, since worn heating elements and failed temperature feedback are the usual faults. Confirm the stirring motor runs smoothly across its speed range and couples reliably to a stir bar. Examine the plate surface for chemical damage and cracks, and ask whether a temperature probe is included, because probes are useful and not always supplied with used units.
Within limits set by its rated capacity and magnet strength, yes, since most units cover from small beakers up to their stated maximum, often one to twenty litres depending on model. Beyond the rated volume the stir bar loses coupling and mixing becomes ineffective. Choose a unit whose maximum comfortably exceeds your largest routine volume, and use an appropriately sized stir bar for the vessel.
Rotor stator homogenisers are specified by the sample volume and the type of material, since tough tissue needs different generator geometry and power than soft samples or emulsions. Confirm the generator probes included cover your volume range, as probes are consumable and application specific. Ask the seller what materials the unit processed, because that indicates both suitability and the wear the generators have seen.
You deal with the seller directly through Machinery Masters, asking about condition, included accessories and testing, then agreeing price and delivery between you with no middleman involved. For inexpensive bench units this is usually quick and straightforward. If you are buying several units or higher value homogenisers, finance on qualifying listings is available to spread the cost.
