BioHub® Single-use Filling System is a pre-sterilized, ready-to-use solution that consists of single-use mixing bag, sterile storage bag, filling bag, single-use capsule filter, filling tubing, single-use aseptic connector, disconnector and single-use filling needle. BioLink is committed to minimizing customer risks by offering top quality consumables, services and support.
Subvisible Particles:
Subvisible particles are tiny, water-insoluble particles with a typical size of 2 µm - 50 µm. Subvisible particles in pharmaceutical injections in quantities exceeding certain limits may pose risks to patients, potentially even life-threatening in severe cases.
Therefore, it is necessary to strictly control the subvisible particles in single-use sterile filling bags that may come into contact with injections.
BioLink controls the level of subvisible particles in products from the source by establishing B+A-level workshop, ensuring a controlled production environment. Processes such as film cutting, welding, assembly are all conducted in B+A cleanrooms, reducing the impact of environment on product subvisible particles. The tubing, connectors and filling needles and other components are pre-flushed to ensure high cleanliness, eliminating visible foreign matter and reducing particle levels.
Sterility Assurance:
To ensure product sterility, BioLink follows the guidelines of ISO 11137:2013 for single-use sterile filling bags, applying the VDmax25 (radiation sterilization) method (i.e. possible SAL of 10-6 in the case of product sterilization with the given minimum dose of 25 kGy). BioLink provides the field distribution verification (PQ) of radiation dose by combining the packaging and loading methods of the product and selecting the packing density limit with the help of an irradiator of the commissioned radiation processor. Verification results indicate that the product was successfully radiated at a required dose of 25 kGy ~ 40 kGy when placed on the radiation pallets. Moreover, BioLink provides the quarterly validation of effective radiation to ensure the stable radiation measurement.
The regulatory agencies worldwide recommend performing pre-use integrity tests on filters and post-use integrity test on sterilizing- grade filters when applying aseptic process. Successful filter integrity tests with the combined inherent sterility and antibacterium of the system constitute a key link of filter verification, smooth processing and product quality.
Flexible Adaptability:
BioHub® Single-use Filling System is superior inflexibility to ensure its adaptation to different scenarios and use requirements. In addition, it secures the minimum costs of cleaning verification, the accelerated interbatch switch and the reduced risks of interbatch- based product cross-contamination.
High Recovery Rate:
The design of BioHub® Single-use Filling System with boat-shaped connectors prevents expensive drug product from remaining in the bag. We tested the recovery rate of eight different designs of filling bags (with 2-12 filling lines) by filling each bag with 5 liters of purified water and then measuring the weight of the residual liquid using gravity. Test results showed that the recovery rate was greater than 99.5% in all cases.
