Laboratory scale mixers
Silverson Laboratory mixers
are suitable for the widest
range of applications - mixing,
emulsifying, homogenizing,
disintegrating, dissolving - with
an efficiency and flexibility
unmatched by other machines.
With a capacity from 1ml up to
12 liters and the ability to mix
in-line with flow rates up to 20
liters/minute, they offer excellent
reproducibility when scaling up
and provide an accurate and
easy means of forecasting the
performance of larger Silverson
machines under full-scale
working conditions.
The Silverson L5 Series is the
latest development in High Shear
Laboratory mixing, ideal for all
routine laboratory work, research
and development, QA analysis
and small scale production in
all industries.
