Dissolution Offline-Kits
“BUDGET” Kit
(storage/doses into tubes only)
The “BUDGET” Offline Kit with fixed stainless
steel sample withdraw tubes to collect into
glass tubes of 10 ml or 25 ml is designed to
serve those customers with a limited budget
and comprises of
1.) 7 stainless steel (316), electro polished,
height adjustable sampling tubes (fix inside
the medium) with external holder for filters
2.) 8-channel Peristaltic pump with Verder-
prene tubing and RS 232 interface for ex-
ternal control
3.) FRL 720 7-channel “silent” Autosampler
with x/y driven arm in “corrosion reduced
design” for collection of up to 25 sampling
intervals into 10 ml glass tubes or 17 sam-
pling intervals into 25 ml glass tubes as
well as support arm to hold a rack.
4.) Tubing/Connector Kit, Teflon
5.) System pre-configuration
6.) Upgraded micro-controller for DT 820 se-
ries to control the complete Offline System
Not included: DT 820 dissolution tester and
collection rack (for glass tubes only)
Operation principle:
The stainless steel (optional Titanium) sample
withdraw tubes are fix installed inside the ves-
sel and can be manually height adjusted (mid-
way between the top of the media and the top
of the rotating basket or paddle). For filtration
purposes a filter can be inserted into a filter
holder positioned at the connection of sample
withdraw tube and Teflon system tubing thus to
minimize influences to the hydrodynamics in-
side the vessel.
The connected pump (8-channel peristaltic
pump) transfers the sample to collect from the
vessel into glass tubes (10 ml or 25 ml maxi-
mum capacity) positioned in the rack at the
Autosampler.
For more precise dosing – after collection – the
x/y driven arm moves down to a selected sam-
ple volume level and pumps back the sample
above this level to the dissolution vessel (over-
filling/levelling principle).
To minimize cross-contamination between of
the media of various sampling intervals there is
an automated tube cleaning routine between
the sampling intervals.
