Three-dimensional agitator

Quick Answer: The Three-dimensional agitator is a benchtop mixer that holds a container at an angle on a driven frame and turns it so the contents move end to end as well as around, blending powders or liquids in three dimensions rather than in one plane.

Movement in Three Dimensions

Most tube rotators turn samples in a single plane. The photo of this agitator shows something different: a closed container held across a frame between two uprights, set at an angle to the axis it turns on, with the drive and controls housed in one upright. Because the container is inclined, each turn tips its contents along the length of the vessel as well as rolling them around it, so the material keeps changing direction.

That three-dimensional path is what makes this type of mixer good at blending, rather than only suspending. Powders of different particle size or density tend to separate on a simple roller; a tumbling, direction-changing motion counters this and brings the blend to an even composition. The same movement keeps dense suspensions, such as slurries or bead mixtures, from settling in one corner.

Container volume, speed and clamping method are not stated in the title, and the motion of the supplied model is worth checking against the task. For single-plane tube mixing, a drum unit such as the Rotary drum digital shaker is simpler to load.

What a 3D Agitator Is Used For

• Blending dry powders, such as reagent mixtures, pigments or pharmaceutical excipients, to an even composition
• Keeping slurries and dense suspensions uniform before sampling
• Coating beads or particles evenly with a liquid or powder
• Classroom demonstrations of mixing: tumbling two coloured sands and timing how long the blend takes to look uniform

Specifications

Safe Operation

• Fill the container to between half and two-thirds of its volume so the contents have room to move.
• Tighten the container clamp and test at low speed before a long run.
• Keep hands, hair and loose sleeves clear of the moving frame and stop the unit before opening the container.
• Wipe the frame and clamp after use, and check fixings periodically for loosening.

Why Choose LabEquip

Pharmacy, materials science and chemistry teaching labs choose a three-dimensional agitator when powders must be blended rather than just stirred. For tilted mixing of tubes and bottles on a rotator drive, see the Drum bottle holder with adjustable tilt; other mixers are in General Lab Products.

Frequently Asked Questions

How is a three-dimensional agitator different from a tube rotator?

A tube rotator turns samples in one plane, so contents move end over end. A three-dimensional agitator adds a changing direction by holding the container at an angle, which tumbles material along and around the vessel and blends it more thoroughly.

Can it mix both powders and liquids?

Yes. Tumbling suits dry powder blends and granules, and it also keeps suspensions and slurries uniform. Thin liquids mix too, although a magnetic stirrer is usually simpler for them.

How full should the container be?

Between about half and two-thirds full. An overfilled container leaves the contents no room to tumble, while a nearly empty one wastes capacity and can let material slide instead of mixing.

How long does a powder blend take?

It depends on the powders, their particle sizes and the fill level. Take small samples at intervals and check uniformity, for example by colour or by measuring a tracer component, until the result stops changing.

Why can powders separate again after mixing?

Particles that differ strongly in size or density can segregate when the blend is poured or vibrated. Mix shortly before use, pour gently and avoid moving the finished blend around more than necessary.

What safety steps apply while it runs?

Keep hands and loose clothing away from the moving frame, secure the container before starting, and stop the unit completely before opening. Wear a dust mask when blending fine powders.
