3.1.1 UNGUATOR® B/R
The UNGUATOR® B/R is the basic machine with controlled
mixing motor and manual jar guidance.
3.1.2 UNGUATOR® e/s
The UNGUATOR® e/s machine was developed for efficient individual and batch preparations.
The automated stroke enables the user to leave the UNGUATOR® e/s during the mixing
process to serve a customer for instance or to prepare the next formulation at the same
time.
The precisely set sensor for the automatic oscillation arm will
always ascertain at each upward or downward stroke the exact
position of the UNGUATOR® Jar bottom or lid. This guarantees
that the UNGUATOR® Jar is always accessible to the UNGUATOR®
Mixing Blade despite the inevitable vertical motion during the
mixing process. If the stroke length of the first stroke was taken
as a constant value, then the active ingredient weighed out in the
lower region of the UNGUATOR® Jar might not be included in the
mixing process by the UNGUATOR® Mixing Blade, getting „lost“
at the bottom. The lifting technique of the UNGUATOR® Mixing
System prevents this from happening, so that the result of the
mixing process is not just a homogeneous ointment, but also one
with the desired ratio of active ingredients.
