This skid-mounted automated buffer preparation system integrates powder dissolution, concentrated stock preparation, online pH/conductivity trimming and inline dilution into one unified workflow, designed to deliver ready-to-use chromatography and process buffers continuously for biopharmaceutical downstream purification lines.
All wetted surfaces are ultra-electropolished 316L stainless steel with hygienic orbital welds and drainable piping layout, supporting full automated CIP and SIP cycles, compliant with cGMP and ASME BPE specifications. The system precisely weighs solid buffer salts or meters concentrated liquid stocks according to stored recipes, completes dissolution and homogenization, then performs real-time inline dilution with purified water at accurate flow ratios, eliminating intermediate holding tanks for pre-diluted bulk buffers.
Online pH, conductivity and temperature sensors implement closed-loop automatic adjustment to lock buffer properties within tight tolerance windows, ensuring exceptional batch-to-batch consistency. Inline dilution directly feeds qualified buffer on demand to chromatography skids, tangential flow filtration systems and other downstream unit operations, drastically reducing large buffer storage vessels, floor space occupation and buffer degradation risks from prolonged holding.
The control system follows ISA-88 batch control standards, stores dozens of buffer formulations for loading, washing, elution, regeneration and sanitization, executes unattended continuous operation, logs all dosing parameters and generates immutable electronic batch records and audit trails, fully satisfying global data integrity and regulatory inspection requirements.
Factory FAT verified skid assembly enables fast on-site installation and seamless interconnection with existing purification workflows. It cuts manual material handling labor, reduces buffer waste and cross-contamination risks, and enables just-in-time buffer supply for continuous biomanufacturing platforms, widely deployed in mAbs, recombinant proteins, viral vectors and vaccine production workshops.
