Buyers should prioritize GSP (Good Supply Practice) compliance, which requires precise temperature and humidity control systems (typically 2-8°C for cold chain or 10-30°C for general medicine) to ensure drug stability. The machine must feature a stable dispensing mechanism, such as an XY-axis elevator system, to prevent fragile packaging from falling and breaking. Additionally, ensure the industrial-grade touch screen is responsive and the internal storage capacity is adjustable to accommodate various medicine box sizes.
