ERWEKA RoboDis
With its RoboDis® ERWEKA sets the
benchmark in the high-end of automated
dissolution testing.
The system has been developed in close co-
operation with Bayer Healthcare® and there-
fore reflects state-of-the-art operational
know-how acquired in over 15 years of
process optimization and automation in
method development and quality control
laboratories. The ERWEKA RoboDis® is a
fully automatic Dissolution Tester capable
of carrying out up to 20 USP Apparatus 1 or
2 tests.
2-in-1
The RoboDis includes two 8-station Dissolution
Testers which are operated by an industrial 3-
axis Robot.
The use of 2 Dissolution Testers increases the
throughput over other automated Dissolution
Systems.
Vessel Filling
As standard the RoboDis® offers volumetric
filling of the vessels.
The actual filling level of each vessel is con-
trolled and documented by control weighing.
Optionally a medium selector is available which
offers using up to 6 kinds of media.
Cleaning
On completion of the test-run the vessels are
emptied by sucking (no valves in the vessel),
remaining tablet debris can be dissolved by
cleaning solution or sucked out by a special
sucking arm and the complete system is
rinsed/sprayed by either water, hot water or a
combination of cleaning solution and water.
A valve allows splitting the used media into
either standard waste water and contaminated
waste water.
Methods
The RoboDis® is designed for the fully auto-
mated performance of up to 20 dissolution tests
according to the latest USP/Pharm.Eur./JP
requirements. It supports the following methods
and processes:
- Performance of tests with USP Apparatus 1
and 2
- Alternate use of method from Apparatus 1 to
2 and vice versa
- USP compliant Basket start routine
- Use of “Japan Sinkers”
The ERWEKA RoboDis is a fully automatic
Dissolution Tester capable of carrying out up to
20 USP Apparatus 2 and 16 USP Apparatus 1
tests.
Filtration
Filtration can be performed by either Tip-Filters
dependant on the analysis system used.
