Laboratory Mixers - Workheads
A comprehensive range of workheads and screens is available for all Silverson high shear mixers. These easily interchangeable workheads offer great versatility by allowing any machine to be adapted to perform a wide range of mixing operations including emulsifying, homogenizing, disintegrating, dissolving, dispersing, blending, particle size reduction and de-agglomerating. Changing from one head or screen to another is quick and simple.
General Purpose Disintegrating Head
This is the most versatile of all the heads, giving an exceptionally vigorous mixing action. Ideal for general mixing applications. It uses also include the disintegration of solids and the preparation of gels and thickeners, suspensions, solutions and slurries.
Square Hole High Shear Screen™
The configuration and fine internal tolerances of this stator provide exceptionally high shear rates, ideal for the rapid size reduction of soluble and insoluble granular solids. It is also suitable for the preparation of emulsions and fine colloidal suspensions.
Suitable for liquid/liquid preparations and especially useful for all emulsions. Available in fine and medium (standard) perforations.
Axial Flow Head
This head expels material vertically upwards instead of horizontally and is used in certain circumstances where aeration needs to be minimized, and to maintain heavy insoluble solids in suspension.
Slotted Disintegrating Head
For the disintegration of fibrous materials such as animal and vegetable tissue, as well as the disintegration and solubilization of “elastic” materials such as rubbers and polymers. Vertical and diagonal slotted heads are available.
This converts the mixer into a non-positive pump which with the use of a flexible hose and valve can be used to fill individual containers.
Tubular Mixing Units
A series of interchangeable Tubular mixing units is available for Silverson Laboratory mixers, suitable for use in narrow-necked containers:
1” Tubular - Supplied with interchangeable screw-on, General Purpose Disintegrating Head and Square Hole High Shear Screen™ or Integral, Open-ended, Vertical Slotted Disintegrating Head.
