Online automated dissolution testing system with 8 position bath.
Fully Automated Tablet Dissolution Testing System
The online dissolution system ADS-L 820 consists of a Pharma Test dissolution tester PTWS 820D, the DAD UV/VIS spectrophotometer TIDAS® L and a multi-channel pump. The system is controlled by the 21 CFR Part 11 compliant user friendly WinDiss ARGUS dissolution software. All instruments are compliant to regulations from USP/JP/CP/EP/USFDA/ASTM and come with a 2 years warranty. One company is responsible for the support of all components.
Automated Dissolution System with the PTWS 820D, IPC pump and TIDAS L
The PTWS 820D
The PTWS 820D is an 8 position 4-by-2 or 2-by-4 dissolution bath with an automated lift system for the instrument head. The media sampling is performed with the EPE-820 moving the sampling tubes into the media to the selected sampling position. Each sampling tube can be equipped with in-line filters to avoid the transfer of undissolved particles into the measurement cells of the spectrometer.
The TIDAS L DAD Spectrometer with Cuvette Changer
J&M’s latest models of laboratory spectrometers, the TIDAS® L series of diode-array spectrometers, follow an approach of integration. The diode array technology gives you rapid results over the full spectrum with each measurement. It feature an integrated Windows based PC with a large, high-resolution touch screen running the WinDiss ARGUS and the additional spectrometer software TIDASDAQ 3. By integrating the PC into the spectrometer unit the TIDAS® L instruments make excellent use of the limited bench space in today’s typical laboratories. The instruments can also easily be connected to the company’s network.
Furthermore, the TIDAS® L spectrometers feature an additional E-ink display which acts as a smart type plate. It shows data like your lab asset or inventory number, the date of last calibration or the due date of the next calibration. Due to the unique nature of the E-ink displays, this information remains visible even when the instrument is turned off. This makes it easy to assess the condition of instrument at a glance. The light in the TIDAS® L is transferred over solarization resistant fiber optic cables from the light source to the detection system. No parts are moving in the light path which gives a very high robustness, reproducibility and stability compared to scanning spectrometers. The use of certified optical fibers in combination with optimized measuring cells ensures reliable measurement results. The TIDAS® L offers an 8-cell changer with 3 additional ports for fiber optic probes. The fiber optic channels can be used to get more detailed information about the dissolution process. All optical parts for these 3 additional channels are included. Only fiber optic probes needs to be added to the system.
The TIDAS® L is a perfect spectrometer for dissolution online tests:
- Very fast measurements of the complete spectra. 6 cuvettes are measured in about 8 seconds.
- More information due to the availability of the complete spectral data results in a higher robustness. Other wavelength and wavelength ranges can be used to perform scattering and turbidity corrections.
- Multicomponent analysis can be performed easily with a Diode Array Spectrometer. Interval times remain very short.

The Multi-Channel Peristaltic Pump
The IPC Pump is a very well known multichannel pump which is suitable for online dissolution measurements. It is used to transfer the dissolution media in closed loop from the vessel to the spectrometer and back to the vessel.
WinDiss ARGUS Software
WinDiss ARGUS is a revolutionary scientific dissolution data management software tool for instrument control and advanced data acquisition, management, processing and reporting – designed by users for users. Whether you perform dissolution tests occasionally or several times each day WinDiss ARGUS will make you more productive in running tests and analyzing results. WinDiss ARGUS simplifies how you collect and report dissolution test results by letting you choose the analysis template that matches the way you work. Whether you are in a QC department concerned about data security, compliance and validation, or need maximum ﬂexibility in the R&D area, WinDiss ARGUS can help your lab to perform more efficiently. Intuitive wizards help anyone in your lab work better – your next dissolution test is running in just a few clicks.
Bringing you faster to reliable results:
- Access dissolution data quickly using relational database technology
- Correct turbidity in your spectra at a second wavelength or by second derivative
- Analyze multi component drugs with models created by CAMO’s The Unscrambler
- Drives spectrophotometers, baths and accessories of the market leaders
- Controls oﬂline sampling, online measurement, fiber optics and even multiple baths systems
- Allows seamless growth from single workstations to a dissolution laboratory network
- Designed for a data-secured regulatory lab environment
The tubing is made out of inert Teflon (PTFE). PTFE has been shown to be suitable for most of the APIs. The IPC pump tubing itself is made out of suitable inert “Pharmed” tubing.
High Quality Cuvettes
We only use high quality flowthrough cuvettes which are designed for dissolution tests. Most important is the material and the accuracy of the pathlength. Pharmacopoeia recommends to have at least a pathlength tolerance of +/-0.005cm. Pathlength of 10mm down to 0.1mm are available with accordance to USP and EP. According to the Law of Lambert Beer the decrease of a pathlength from 10mm to 1mm is equal to a dilution of 1:10. Therefor smaller pathlength are used if the concentration of the product is high.
Principle Online Dissolution Testing System
The multichannel IPC pump is used to transfer the media from the vessels to the spectrometer. The samples here are circulated in a closed loop so that there is no sample volume loss over the time of the dissolution test. At the programmed time point the sample circulation is stopped and either a single point absorbance reading or a full UV/VIS spectrum of each vessel is collected. The control of the entire system as well as the data handling, calculation and reporting is performed by the 21 CFR Part 11 compliant WinDiss ARGUS Software.
