Description
Digital stirrer HT-50T is a laboratory overhead stirrer with external controller for mixing volumes up to 40 L. The unit operates over a speed range of 50–1000 rpm and handles viscosities up to 60,000 mPa·s, with motor power of 83/75 W. Housing dimensions are 155 × 180 × 110 mm and the stated weight is 3,5 kg; power supply is 230 V, 50/60 Hz. The separate external controller keeps the drive head compact while allowing convenient speed adjustment away from the vessel. Suitable for dissolution, suspension and general mixing work in analytical, formulation and teaching laboratories, this model from manufacturer Witeg delivers controlled mechanical agitation for medium-batch applications. Digital speed control supports reproducible settings across the full rpm window, helping maintain consistent process conditions when stirring aqueous or moderately viscous media on the laboratory bench.

Questions about Overhead stirrer HT-50T digital
What is this article?
Overhead stirrer HT-50T digital is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Magnetic stirrers, inside Stirring, shaking & mixing, in Lab instruments.
A magnetic stirrer is the motor and the plate under the flask. Many also heat. The stirring capacity is the litres of a water-like liquid it can turn, and a viscous liquid defeats a rating that was measured on water.
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.
