Automated sample preparation workstation for content uniformity testing
In laboratories conducting content uniformity (CU) testing, repetitive tasks like sample weighing, extraction, and dilution can be time-consuming and prone to human error. This manual process hampers productivity and may lead to inconsistent results, especially when dealing with various dosage forms.
Automates sample weighing, extraction, and filtration
The TPW Automated Sample Preparation Workstation from Sotax AG is designed to enhance laboratory productivity by automating critical repetitive tasks associated with sample preparation. The workstation streamlines the entire process, from sample weighing to extraction and filtration, ensuring consistent volumetric preparations confirmed gravimetrically at every step. Features include a high-shear homogenizer for efficient wet grinding and reproducible extraction of challenging dosage forms, and a fluid metering pump for precise filtration and dilution. The built-in HPLC injector supports on-line analysis, with the system capable of transferring samples to various analysis devices such as UV spectrophotometers. This makes TPW ideal for laboratories focusing on content and blend uniformity analysis, improving efficiency and safety by reducing exposure to hazardous reagents.
