Homogenisers & dispersers

Match the disperser and its dispersing element to your working volume. Battery handhelds suit small volumes in tubes and vials. Compact bench units handle up to around 1.5 litres of water-like liquid, such as the T 18 mini digital ULTRA-TURRAX®, 3000–25,000 rpm, and the T 25 mini control ULTRA-TURRAX®, 600–25,000 rpm; the dispersing element is ordered separately. For water samples up to 5 litres there is a water sample homogeniser to DIN 38402 A 30, complete. Viscous samples need more power. Send your sample details to sales@luminixhealth.com.

The element's geometry decides the result. A G-type element is an all-purpose tool that produces relatively fine suspensions and emulsions and also handles solids added to a liquid. An F-type element gives extremely fine emulsions, down to about 1 µm, as long as viscosity stays fairly low. The diameter must suit your vessel and volume. Examples, both 30 mm and made for a 5-litre laboratory reactor with T 25 digital drives: G type and F type. Check that the element fits your drive before you order: sales@luminixhealth.com.

A battery disperser has no cable, so you can use it in a fume hood, a safety cabinet or out in the field, and it is quick to pick up for small samples. An example is the ULTRA-TURRAX® T 10 battery dispersion unit, 8000–30,000 rpm. A complete set with the S 10 N-5 G dispersing tool, H 44 clamp and R 104 stand is also available. Mains-powered units run longer at constant power and suit larger volumes and longer runs. The batteries are lithium-ion, which matters for shipping. Browse homogenisers and dispersers.

A magnetic stirrer mixes gently and keeps a solution moving for hours, which is enough for dissolving, heating or keeping a suspension homogeneous. A disperser works with a rotor-stator at high speed and applies strong shear: it breaks up particles, makes emulsions and disrupts tissue or cells within minutes. So choose a stirrer for mixing and a disperser for size reduction. A compact disperser for this work is the T 18 mini digital ULTRA-TURRAX®. For gentle mixing, see magnetic stirrers. Unsure? Ask sales@luminixhealth.com.

A homogeniser or disperser uses a rotor inside a stator to tear a sample and disperse it. Tip diameter and speed decide the particle size. A generator for 2 mL and a generator for 1 L are different tools on, sometimes, the same drive.

Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
