This Buchi 25L EX Mixer Blender is a blender and mixer — a category of industrial processing equipment also referred to as a mixing vessel or stirred reactor — designed for blending, dispersing, and homogenising materials in a controlled, enclosed environment. Büchi is a well-regarded Swiss manufacturer with a long-standing reputation in laboratory and process equipment, particularly in the fields of chemistry, pharmaceuticals, and related industries where precision and material compatibility are essential.
The unit is built around a closed borosilicate glass 3.3 stirring vessel with a capacity of 25 litres. The vessel measures 300 mm in diameter by 400 mm in height and features a dished bottom, which promotes thorough mixing and efficient drainage. A dedicated outlet is fitted. Borosilicate glass 3.3 is chemically resistant and thermally stable, making it well suited to demanding process conditions. The vessel is mounted on legs with wheels, giving the unit both stability and ease of repositioning, with a floor footprint of 0.60 × 0.60 metres and a total height of 2.0 metres.
Mixing is provided by a propeller stirrer, with the mixing shaft running at 550 rpm. The notes also reference a double segment stirrer configuration rated at 1 bar plus 0.4 bar. The drive motor is rated at 0.35 kW, operating on 220/380 V at 1,390 rpm, and is specified as EX-rated, making the unit ATEX compatible for use in potentially explosive atmospheres. A switch is included as standard.
Operating conditions span a maximum temperature range from −50 °C to +200 °C. The working pressure is 0.4 bar, and vacuum operation is also possible. This combination of pressure, vacuum, and temperature capability broadens the range of mixing and processing applications the unit can support.
The machine dates from 1990, is offered in used condition, and is located in Barneveld, Netherlands (internal reference number 109900).
