ZRS-8ST
Dissolution Tester
Range of application：
It’s used to examine the dissolving speed and degree of solid preparations like drug tablets or capsules in the specified solvents. ZRS-8ST dissolution tester is a kind of new type drug dissolution tester which is developed and produced by our company; it adopts classical modeling design and is featured by high cost performance, stability, reliability, simple operation and durability.
Main features:
l ZRS-8ST is a double-functional model with electric lifting head and head overturn; it only needs to manipulate the keyboard when paddle rod or basket rod is replaced, the head can be lifted automatically; the head can be overturned continuously based on the lifted head to make the work of paddle change more convenient and handy.
l Available for installation of 8 basket rods or paddle rods.
l Available for installation of 8 new dissolution cups with the height of 185mm and shading dissolution cups as well.
l Friendly human-computer interface, with simple and convenient operation.
l All the working parameters can be preset and saved automatically, without the need to set repeatedly when the instrument is started next time
l Accurate rotating speed, steady operation and low energy consumption.
l Thermostatic water bath adopts built-in integrated temperature sensor and new software and hardware temperature measurement and control mode, which is featured by fast temperature rise and high precision; temperature deviation can be corrected with software conveniently.
l Independent operation of startup, pause and reset for experimental timing.
l Automatic protection functions such as self-inspection fault alarm and over-temperature protection, etc.
l The paddle rod, basket rod and basket turning body are all made of stainless steel material meet the requirements of Chinese Pharmacopoeia in quality and performance.
