Description
Analog stirrer HS-120A is a compact laboratory overhead stirrer designed for reliable mixing of liquid media up to a maximum volume of 20 L. It offers an analog speed control range of 200 to 3000 rpm and is rated for viscosities up to 10.000 mPas, making it suitable for routine stirring tasks in research, quality control, and process development laboratories. Motor power is specified as 130/120 W, supporting continuous operation across the full speed band. Unit dimensions are 90 x 145 x 180 mm with a stated weight of 5,3 kg, so the instrument fits easily on crowded benches while remaining stable in use. Electrical connection is 230 V, 50/60 Hz. Scientific specifications list a nominal torque of 145 N·m together with minimum and maximum speeds of 3,33 1/s and 50 1/s respectively, aligning with the stated rpm window. This model from manufacturer Witeg is intended as a straightforward analog drive unit for standard laboratory vessels and media. Pack size is 1 pc. Ideal for general-purpose stirring where simple, durable analog control is preferred over digital interfaces.

Questions about Overhead Stirrer HS-120A analog
What is this article?
Overhead Stirrer HS-120A analog is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Overhead stirrers, inside Stirring, shaking & mixing, in Lab instruments.
An overhead stirrer drives a shaft from above, for volumes and viscosities a magnetic bar cannot move. Torque and speed range are the ratings. The chuck and the stand are part of using it. A high-speed disperser is a different head.
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.
