Dosing System + Magnetic Stirring Tank | Automated, Precise, Aseptic Dosing Solution for Pharmaceutical Manufacturing
💡To address the challenges of high human error, uneven mixing, susceptibility to contamination, and batch-to-batch inconsistencies, we employ a combination of an automated solution preparation system and aseptic magnetic stirring tanks. This solution ensures precise ratios, aseptic homogenization, and data traceability, and is suitable for GMP solution preparation processes for oral solutions, injectables, vaccines, and biologics.
I. Industry Challenges
The precision of the solution preparation and drug formulation processes directly determines the quality and stability of pharmaceutical products. Traditional manual solution preparation suffers from significant measurement errors, uneven mixing, and a high risk of contamination, leading to concentration fluctuations between batches and localized inconsistencies in therapeutic efficacy; in severe cases, this can even compromise product compliance. Particularly for sterile preparations, exposure at any stage of the process may pose a risk of microbial contamination.
II. Solutions
Dosing System + Magnetic Stirring Tank — Integrated, Precise, and Sterile Dosing
We utilize a liquid preparation system that works in conjunction with a magnetic stirrer tank to achieve fully automated, aseptic operations throughout the entire process—from material metering and conveyance to mixing and homogenization. This completely eliminates human error and the risk of contamination, ensuring that each batch of pharmaceutical solution has uniform concentration and consistent quality, making it suitable for high-end aseptic pharmaceutical production lines.
III. Key Advantages of Each Equipment Category
✅ Automated Liquid Dispensing System | Precise Measurement, Digital Compliance for Medication Dispensing
The system supports preset process formulas and automatically handles the metering, conveying, and blending of solid and liquid materials, with blending accuracy controlled within ±0.5%, completely eliminating errors caused by manual weighing. Data is automatically recorded throughout the entire process, and batch records are traceable, meeting GMP data integrity audit requirements. At the same time, this reduces manual contact during material feeding, thereby lowering the risk of contamination and occupational exposure.
✅ Magnetic Stirring Vessel | Aseptic homogenization, gentle mixing that preserves cell viability
Features a magnetic drive structure without mechanical seals, ensuring zero leakage and no dead zones in mixing. The material flow direction is precisely controlled via adjustable speed, completely eliminating concentration gradients within the tank, with solution homogeneity reaching 98% or higher. It supports online CIP cleaning and SIP sterilization, operating under fully sealed, aseptic conditions, and is suitable for high-grade clean production of sterile injectables, vaccines, and bioproteins.
