Membrane rinsing system
The HF Bundle rinsing station (Me-Sep) is designed for the removal of residue solvent after the production of hollow fiber membranes. Bundles of hollow fibers are placed in one of six stainless steel tubes and rinsed with heated water. Flow speeds can be altered for each rinsing tube individually or be turned off entirely to allow for the use of a singular rinsing tube. Available in laboratory ZH279. For further questions or specifications, please feel free to contact the AOT department.
· Fiber bundle length of 439 mm
· Maximum tube diameter of 42 mm
· Water in- and outflow of 1-11 L/min
· Recirculation rate between 5 and 35 L/min
· Maximum pressure of 6 bars
Drying station
The Fiber and Module Dryer (Me-Sep) is designed for drying hollow fiber bundles or filters. Heated air is passed by and through the membrane to ensure the removal of any residual non-solvent. The air temperature is monitored during multiple steps of the drying process to ensure a stable continuous drying of the fibers. A total of 6 bundles or filters can be dried simultaneously. Available in lab ZH279. For further questions or specifications, please feel free to contact the AOT department.
· Drying temperatures up to 60 °C
· Preferable pressure range of 0.1 to 0.5 bar per filter
· Maximum total pressure of 6 bar
Centrifuge
The RM Midi potting centrifuge (Me-Sep) is used for centrifugal potting of hollow fiber dialyzer modules. Centrifugal potting ensures homogenous sealing of the filters. Multiple dialyzer sizes, lab- and commercial scale, can be potted using different sized rotors. Two dialyzers can be potted simultaneously. Available in lab ZH279. For further questions or specifications, please feel free to contact the AOT department.
· Max filter length of 335 mm
· Max diameter of 45 mm
· Rotation speed can be set between 200 and 1000 rpm
· Temperatures of up to 50 °C
· Compatible with various resins like Epoxides, polyurethanes, silicones, etc.
Device integrity tester
The HF filter integrity tester (Me-Sep) is a membrane test device capable of performing pressure decay tests on hollow fiber filters of various sizes. The system consists of a vacuum pump, a testing rig to which the filter is attached, and the integrity tester. By wetting the membrane and its pores entirely, then applying pressure from the lumen side, and lastly closing of the air supply, the pressure decay can be measured. This Pressure decay provided insight into the viability of the tested filter module. The HF filter integrity tester is located in lab ZH280. For further questions or specifications, please feel free to contact the AOT department.
Glue mixer
The two-component adhesive dispenser (Me-Sep) is a portable glue gun for precise dispensing of various types of two-component glues. Presets for multiple glues are available but dispense protocols for other types of adhesives can be set. Available in lab ZH279. For further questions or specifications, please feel free to contact the AOT department.
· Glue volume between 0.1 and 300.0 mL
· Glue viscosity range of 2,000 – 10,000 mPa⋅s
· Capable of dispensing forces up to 3000 N
· Temperature range of 10-40 °C
· Compatible glue types: Epoxy, polyurethane, silicone, other two-component glues
Precision cutter
The precision cutter, available in the advanced organ bioengineering and therapeutics (AOT) department, can slice through a potted hollow fiber module, maintaining a clean cut all the way through. The precision cutter is designed for cutting commercial sized dialyzers. For smaller, lab-scale dialyzers, housings are available to ensure a steady hold while slicing. Available in lab ZH279. For further questions or specifications, please feel free to contact the AOT department.
Packaging for sterilization
The polystar® 250MV, available in the advanced organ bioengineering and therapeutics (AOT) department, is a medical grade sealer device for sterile packaging of samples. In the department, it is used for the storage of in-house developed membranes. Available in lab ZH279. For further questions or specifications, please feel free to contact the AOT department.
