Hanson dissolution testers

The Vision G2 Elite8 and Classic6 dissolution testers, designed by the American Hanson Research company founded in 1951, gain respect among the laboratory workers of the pharmaceutical development and quality control not only with their reliability, preciseness and easy-to handle characteristics but also with their sophisticated, aesthetic appearance, as well. In accordance with the requirements of today’s digital era, the Elite8 and Classic6 have color touch screen, icon-driven internal software, internal memory capable of storing up to 100 protocols, saving onto USB stick and network printing possibilities. The instruments are suitable for carrying out dissolution tests in accordance with the USP, EP and JP, as well as the ASTM requirements, and meet the 21 CFR Part 11 compliance, as well. They are also suitable for basket (Apparatus 1), paddle (Apparatus 2), low-volume paddle, “Ointment cell “, “Paddle over disk ” (Apparatus 5) and “Rotating cylinder” (Apparatus 6) dissolution tests.


The Vision G2 Elite8 instrument is suitable for placing 8 dissolution vessels, from which the sampling is possible both manually and automatically. In its standard configuration, it can be used with 1-liter vessels, but it may be adapted to the use of 2-liter or 150-ml vessels. In the case of automatic sampling with simultaneous tablet dropping, with the sample probes immersing in the medium only at the time of sampling and with temperature sensors per vessel (6 or 8 positions) will the examination of the dissolution be fully documented. To achieve completely metal-free fluid paths, the use of plastic sample probes is possible. With its well-thought modular expansion possibilities it can be transformed into online spectrophotometric and fraction collecting systems, as well. With the help of the evaporation free covers, there is no measurable dissolution medium evaporation in the case of prolonged tests.

The Vision G2 Classic6 instrument is for 6 dissolution vessels, from which the sampling is possible both manually and automatically depending on the configuration. In its standard configuration it can be used with 1-liter vessels, but it can be adapted to vessels of 150 ml. The automatic sampling is carried out through a cannula with fixed, manually adjustable depth, while the sample filtering is done with the cartridge filter placed in the sample probes. It can also be coverted into online spectrophotometer and fraction collection system with its modular expansion possibilities.
