Overview

The ERWEKA DT light Series delivers the proven ERWEKA quality in a comprehensive package for a budget for simple dissolution testing with USP method 1, 2, 5 and 6. The DTs are equipped with 6, 8 or 12 test stations and a fixed drive head (high-head), allowing easy access to each 1000 ml vessel.

The shafts can be replaced easily and the unique water bath of moulded PET is equipped with the time-proven ERWEKA water outlet for easy clea-ning. The external flow through heater reduces the influence of external vibrations and ensures a constant temperature. Every accessory that comes into contact with the dissolution sample is installed in Germany. Therefore our DT light Series has the ERWEKA made in Germany quality.

All these features make sure that the ERWEKA DT light Series offers the perfect entry-level devices for the world of dissolution testing.

The ERWEKA DT 950 Series is our first digital dissolution tester on the market, equipped with the most advanced technology for the requirements of today and the challenges of tomorrow.

With state-of-the-art embedded PC technology, the DT 950 is the first of its kind. The 7″ touch display with a modern user interface focuses the user on the most important task the DT 950 has to fulfill – 100% USP/EP/JP compliant dissolution testing, without distractions and errors. For this purpose, we have designed the ERWEKA TestAssist, an intelligent helper that guides the user step by step through the con-figuration of the dissolution test, provides assistance and makes sure that only compliant parameters can be entered.

The water bath, made of non-leaking PET, is effortlessly accessible and allows for easy cleaning.In addition to the modern user interface, the DT 950 is completely future-proof. With our “Upgrade your DT” programme, it can be upgraded at a later date – e.g. from 6 up to 8 test stations, with an automatic tablet drop or an automatic sampling station, if the DT 950 is to be upgraded to a dissolution system at a later date. A switch form low-head to high-head mode is also easily possible at all times. Thanks to the advanced embedded system, software functions for the touch display can also be added later.

With all these innovations, however, we have not lost sight of the most important thing: The DT 950 Series are 100% USP/EP compliant.

The ERWEKA DT 9510 Series is the bigger sibling of the digital DT 950 Series.

Controlled by the same embedded PC, every component of the DT 9510 is focused on reliable, high volume digital dissolution testing: The test stations (up to 14) are driven by a single, powerful motor and the big waterbath holds the temperature stable due to the thermal inertia of water. This ensures that parallel testing of two batches of samples can be done at precisely the same conditions, making comparsion between the two as reliable as possible and 100% USP/EP compliant.

With the new optional AirLift system, the dissolution head of the DT 9510 can be simply raised and lowered by the press of two buttons. Furthermore, DT 9510 Series has the same features as it‘s smaller sibiling – digital dissolution testing is done with the help of the latest version of the testing assistant TestAssist and samples can be automatically dropped into the vessel by the optinal automatic tablet drop.

Overview

The ERWEKA DT 820 series offers advanced intelligence and user-friendly features for stand-alone operation or control of a complete dissolution offline sampling system. It allows storage of up to 60 product test run parameters that can be recalled for future tests.

The unit can be equipped with 6, 7 or 8 test stations and be used in standard high-head or low-head mode. It provides an OQ traffic light to show USP/EP compliance as well as an external temperature sensor for checking the water bath temperature.

The water bath, made of non-leaking PET, is effortlessly accessible and allows for easy cleaning.

Overview

The ERWEKA DT 1610 series offers advanced intelligence and features for stand-alone operation or the control of a complete dissolution offline sampling system. It allows storage of up to 60 product test run parameters.

The DT 1610 series is based on the proven DT 820 (similar user interface, e. g. keypad, display and menu structure) and can be equipped with 12, 13 or 14 test stations arranged in two rows. The unit can be operated in high-head as well as low-head mode.

It provides an OQ traffic light system to show USP/EP compliance and an external temperature sensor for checking the water bath temperature. The water bath is designed for easy access and cleaning.

Additionally, the DT 1610 series enables testing of high capacities. Thanks to the exceptional configuration, the device allows running two different batches of the same product or two different products with the same dissolution monograph at the same time.

Overview

The ERWEKA Dissolution Offline System is the ideal semi-automatic solution for dissolution testing with automated sampling and subsequent sample storage for later analysis. The system is controlled by a DT 820 series dissolution tester with advanced intelligence.

The DT 820 series equipped with i-Version comes with integrated intelligence for controlling the offline sampling system, which consists of an auto sampling station ASS-8 connected to the DT, a pump (peristaltic or piston) and the sample collector of the FRL series for storing the samples into glass tubes or sealed HPLC vials.

This configuration does not require an additional PC or any software and therefore saves space, money and last but not least software validation work.

Overview

The ERWEKA dissolution online systems are the perfect, semi-automatic solutions for dissolution testing with automated UV/VIS online analyses.

The DT 720 with the integrated, automated ASS-8 sampling station transports freshly sampled media directly to the UV/VIS analysis device (several brands available). There, the samples can be measured and the results can then be stored within our advanced Disso.NET dissolution software.

ERWEKA offers different types of UV/VIS analysis devices, such as the Shimadzu 1900, the Analytic Jena Specord 210/8 or the Agilent Cary 8454. All combined with our dissolution tester DT 720 and a peristaltic pump IPC 8 and all controlled by the Disso.NET PC software.

Overview

The MediPrep 820 series offers quick and easy preparation of up to 8 liters dissolution media in less than 15 minutes. The MediPrep 1622 only needs 25 minutes to prepare dissolution media – 3 times faster than manually done according USP! In a single pass, the media for dissolution tests can be precisely mixed, heated, degassed and gravimetrically filled into vessels. Foaming media like SDS (Sodium Dodecyl Sulfate) can also be used.

Filling can be done at the integrated dosing port or with the optional remote filling hand directly into the vessels.

The MediPrep 1622 additionally provides two inlets for premixed media and one outlet for wastewater. To prevent cross contamination, an automated cleaning procedure is integrated.

Overview

The ERWEKA DRT is the perfect device for testing of in vitro releases of substances from chewing gums and other dosage forms, that have to be masticated, into the surrounding liquid medium. The vertical up and down strokes of the lower jaw in combination with a revolving movement of the upper jaw provide ideal mastication of the chewing gum and at the same time an agitation of the test medium.

For manual sampling, emptying and cleaning the lower jaw with the test cell can be lowered into a down position, so that the chewing process stops. The test cell, the upper and lower jaw can then be easily removed. A water circulation system controls and regulates the water temperature in the test cell around the media. The chewing gum test apparatus is used to chew gums and analyzes then the speed at which various substances leave the gum (release). In addition, the device is very helpful for developing candy chewing gums, but it can also be used for unusual purposes such as testing of snuff bags.

As the DRT offers a modular design, any number of chewing gums can be tested with the DRT-6 at the same time, with 6 test stations the most commonly used. The cells can be equipped with additional accessories for measuring variables such as the pressure of chewing gums, torque at shear force (twisting motion), pH-value and temperature. All measurements are logged into a data collector and can then be printed out.
