Deeply Rooted in the Aseptic Barrier Track for Cell Therapy | HjClean’s Cell Isolators Empower High-Quality Industrial Development of Biomedicine

In recent years, the domestic cell therapy, regenerative medicine and gene therapy industries have accelerated into the stage of clinical translation and large-scale manufacturing, accompanied by continuous improvement of the regulatory framework. GMP compliance, fully closed-process preparation and controllable contamination risks have become core requirements for cell industrialization. As a high-tech enterprise with over two decades of expertise in aseptic and ultra-clean environments, Suzhou HjClean Technology Co., Ltd. keeps upgrading its product portfolio of cell processing isolators. With enclosed Grade A aseptic microenvironment technology, the company builds a solid safety barrier for the R&D, pilot production and commercial manufacturing of cell therapies, supporting the independent and controllable upgrading of China’s cell industry chain.HjClean cell isolators feature rigid enclosed chambers constructed from SUS316L stainless steel, equipped with HEPA high-efficiency filtration systems, VHPS vaporized hydrogen peroxide sterilization and residual vapor exhaust systems, intelligent differential pressure, temperature and humidity regulation, online glove integrity monitoring, and RTP rapid transfer ports. The equipment can consistently maintain an ISO 5 (Grade A) clean environment inside the chamber, fundamentally eliminating cross-contamination introduced by operators, ambient environments and materials. It preserves cell viability and batch-to-batch consistency while enabling full process traceability, and protects both operators and the external environment. Compliant with domestic GMP, YY/T 0567 and other relevant standards, the isolators support manual glove operation as well as integration with automated modules to accommodate diverse process requirements.In terms of application coverage, Hongji Clean cell isolators serve the full spectrum of scenarios across the cell industry chain:

✅ Immune cell therapy: Fully enclosed preparation workflows including sample receipt, sorting, activation, gene transfection, expansion, harvesting and filling for CAR‑T, NK, TIL and other cell products, suitable for commercial production lines of cell therapies and clinical-grade preparation centers;

✅ Stem cells and regenerative medicine: Isolation, culture, subculture and pre-cryopreservation processing of mesenchymal stem cells and hematopoietic stem cells, supporting stem cell banks, tissue engineering and wound repair-related R&D and manufacturing;

✅ Biological samples and clinical laboratories: Aseptic processing of clinical specimens, cell testing, sterility testing and isolation & culture of rare primary cells, serving translational medicine centers in tertiary hospitals and third-party CRO/CDMO laboratories;

✅ Advanced biological agents and research platforms: Organoid culture, monoclonal cell line development and construction of gene-edited cell models for universities, research institutes and innovative biotech enterprises;

✅ High-potency biological material handling: Negative-pressure isolation options are available to satisfy biosafety control requirements for high-potency cells and pathogen-associated biological samples, with customizable positive and negative pressure isolation schemes.Looking ahead to industry trends, cell therapy industrialization is shifting from small-batch clinical preparation toward large-scale, automated and digital manufacturing. End-users now demand more than basic aseptic handling functionality from isolation equipment, with growing focus on process integration, data compliance, flexible customization and production line interconnection. Leveraging its provincial Engineering Technology Research Center platform, Hongji Clean will advance along three key directions:

First, promote modular and flexible upgrading of cell isolation systems. The systems are compatible with integrated setups incorporating centrifuges, CO₂ incubation units, liquid handling workstations and microscopic observation modules to form all-in-one cell processing workstations. This enables rapid switching between different cell process workflows and shortens production line construction timelines.

Second, strengthen digitalization and validation systems. Enhance electronic records, audit trails, automatic validation of sterilization cycles and real-time uploading of environmental parameters, with connectivity to LIMS and MES systems to meet data traceability requirements for cell therapy product filings and regulatory inspections.

Third, continuously drive cost reduction and efficiency improvement for domestic aseptic isolation technology. The company provides isolator maintenance, validation services and compatible single-use consumable solutions, while expanding into overseas regulated markets. Hongji Clean delivers an integrated total solution for cell factories covering isolation equipment, on-line monitoring instruments and cleanroom engineering.
