SOTAX 7smart CY7-50 Piston Pump

Insufficient attention is sometimes paid to requirements when choosing a suitable pump for automatic sampling. The pump is, after all, an important component and often the reason for unsatisfactory results with automated dissolution tests. We therefore recommend a 7-fold piston pump for sampling purposes. SOTAX CY piston pumps have proved to be ideally suited for this purpose. Two fundamental features have proved to be particularly advantageous:

• Adsorption/desorption problems are ruled out. All parts coming into contact with medium and samples are made of inert materials such as glass, stainless steel, teflon etc. Teflon is used through the entire tubing system.
• High suction performance guarantees trouble-free sampling even if filter resistance increases steadily during the test.
• Accurate sample delivery and media adding methods
