This Vollrath EWTHV-0,5 is a laboratory mixer and blender — sometimes referred to as a dissolver or high-speed disperser — designed for mixing, blending, and dispersing materials in small-batch or laboratory-scale applications. Vollrath is a recognised manufacturer of specialist mixing and dispersing equipment, supplying laboratory, chemical, and industrial process environments with precision-engineered machines built for demanding formulation work.
This used unit dates from 1998 and is located in Barneveld, Netherlands. The machine is driven by a 0.37 kW motor rated at 380 V and 1,390 rpm, and is equipped with a variable speed drive that allows the mixing shaft to operate across a wide range of 260 to 1,820 rpm, enabling fine adjustment of shear and mixing intensity to suit different materials and viscosities.
The dissolver is fitted with interchangeable disc options in diameters of 30, 50, 65, and 90 mm, providing flexibility for different vessel sizes and batch volumes. The distance between the shaft and the frame measures 200 mm, and the machine incorporates a mechanical lifting system with a maximum stroke of 250 mm, allowing the shaft and disc assembly to be raised and lowered to accommodate vessels of varying heights. A switch is fitted as standard.
Notably, this machine is ATEX compatible, making it suitable for use in environments where explosive atmospheres may be present — a relevant consideration for laboratories and production areas handling solvents or other flammable substances.
The machine has a compact floor footprint of 0.55 × 0.45 m and a total height of 0.90 m, making it well suited to space-limited laboratory settings. The unit carries the internal reference number 19.36 and is offered in used condition.
