1. Equipment Overview & Global GMP Compliance Standards

Our custom downstream processing equipment delivers fully tailor-made sanitary hardware dedicated to purification workflows of all biological therapeutics, fully compliant with FDA cGMP, EMA Annex 1, PIC/S PI 006-4 and ICH Q7–Q10 data integrity and cleaning validation requirements. The product portfolio covers capture, intermediate purification, polishing, viral clearance, buffer exchange and sterile bulk handling for monoclonal antibodies, recombinant proteins, ADCs, viral vectors and vaccines. Differentiated from standard off-the-shelf purification skids with fixed flow rates and rigid layout, our custom manufacturing resolves core downstream pain points: mismatched throughput with upstream bioreactor output, excessive target product loss, insufficient impurity clearance capacity, dead-leg-prone pipeline design and incompatibility with single-use closed transfer systems. We supply audit-ready, process-customized downstream hardware for lab-scale process development, clinical pilot campaigns and large-volume commercial biomanufacturing plants worldwide.

2. Core Customization Philosophy & Biologics Downstream Advantages

Designed around product-specific critical quality attributes (CQAs) and impurity removal targets, all structural, hydraulic and control customization prioritizes protein stability, maximum recovery and simplified regulatory validation.

1.Process-matched hydraulic customization

Skid flow paths, pipe diameters and pump performance are customized based on feed titre, target throughput and viscosity of cell culture harvests; low-shear fluid design minimizes protein aggregation and denaturation for fragile biologics including ADC intermediates and viral vectors.

2.Full sanitary customizable construction

All wetted components adopt 316L sanitary stainless steel with polished surface Ra ≤0.4–0.6 μm; zero-dead-leg orbital welded piping, customizable valve manifolds and fully enveloped CIP/SIP circuits eliminate residual protein, endotoxin and cytotoxic payload cross-contamination risks.

3.Modular flexible expandable architecture

Independent customizable functional units (chromatography, TFF, virus filtration) support parallel operation, multi-product switching and process intensification upgrades such as continuous multi-column chromatography without full skid replacement.

4.GMP integrated automated control customization

Configurable PLC control with customizable purification step sequences, inline PAT sensor interfaces and tamper-proof electronic batch recording; automatic interlocks for pressure, flow and conductivity deviations to avoid product batch loss.

Compared with universal standard downstream equipment, our customized design improves overall process yield by reducing hold-up volume, shortens purification cycle time and greatly reduces the workload of cleaning validation and regulatory audit preparation.

3. Four Core Custom Downstream Equipment Modules & Standard Deliverables

The complete custom downstream processing equipment system consists of four interlinked, independently customizable modules covering full post-harvest workflows: customized chromatography systems, tangential flow filtration (TFF) skids, viral safety processing units and integrated buffer & holding systems.

1.Custom Chromatography System Module

Custom-sized axial/radial flow chromatography columns, multi-column continuous capture skids, automatic buffer gradient preparation assemblies and integrated fraction collection units; adjustable bed height, flow velocity and column docking interfaces matched to client resin and production scale. Full FAT testing records and cleaning validation support documents are provided.

2.Custom TFF & UF/DF Filtration Module

Tailor-designed single-pass or recirculation tangential flow filtration skids for harvest clarification, concentration and buffer exchange; customizable membrane cassette housings, low-shear sanitary feed pumps and retentate/filtrate diversion manifolds for perfusion and fed-batch upstream matching.

3.Custom Viral Clearance Processing Module

Independent, isolated custom viral filtration skids with dedicated SIP loops; customized low-temperature holding vessels for viral inactivation steps, closed sterile transfer interfaces to prevent exogenous viral contamination, specifically optimized for viral vector and vaccine production lines.

4.Custom Buffer Preparation & Intermediate Storage Module

Custom-volume multi-temperature buffer mixing tanks, automatic powder dosing systems and inline buffer dilution units; fully sealed intermediate storage vessels with customizable sampling ports and closed transfer connections to eliminate open operation exposure.

4. Industrial Application & Full Lifecycle Engineering Support

Our custom downstream processing equipment is widely applied in new greenfield biologic plant construction, brownfield production line intensification retrofits, clinical pilot process development platforms and multi-product flexible CMO manufacturing bases. All modular customized equipment reserves expansion interfaces for continuous downstream transformation, capacity expansion and new therapeutic pipeline iteration.

We provide full-lifecycle technical services including pre-sales downstream process matching customization consultation, structural hydraulic optimization, factory FAT performance verification, overseas on-site SAT linkage commissioning, GMP operation training and long-term spare parts supply & process iteration optimization. By fully aligning hardware design with unique purification process requirements of different biologics, our custom downstream equipment achieves stable impurity clearance, maximizes target product recovery, lowers long-term production costs and accelerates the global regulatory commercialization of novel biotherapeutics.
