Stirring [Code: PCE0048]

Description & Specification:

Stirring Technical Description During stirring, the continuous phase is liquid. With , the production of solutions (solid dissolved in liquid), emulsions (mixture of non-inter-soluble liquids) and suspensions (insoluble solid in liquid) can be investigated. Mixing takes place in a tank which is resistant to chemicals and heat-resistant. With the high-performance stirring machine even high-viscosity mixtures can be produced. The speed is adjustable. The torque is indicated on the unit’s digital display. This enables the power demand to be determined. 9 different, easily interchangeable stirrers are provided. With a plastic which is dispersed in the water it is possible to observe the characteristic flow fields of the different stirrer types. Flow impeders can be inserted in the tank to investigate their influence on the mixing process. To determine the mixing time and mix quality of solutions, a conductivity meter is available. The device can also be used to measure temperatures. A removable tube coil serves as a heat transfer medium. It can be used for heating or cooling with water from the laboratory supply. A valve with precise adjustment is used to adjust the flow rate. This enables the influence of mixing processes on heat transfer to be investigated.   The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
