UniFill 5
Automated dispensing system for the filling of open and closed vials
The automated dispensing system UniFill consists of the lead shielded class A dispensing cell and the directly connected class B pre-chamber. The dispensing system is installed inside the dispensing cell. The shielding at the front side can be lowered for the inactive preparation of the dispensing system through the glove ports. Lead plugs are available to perform the preparation under active conditions. Dispensing cell and pre-chamber are both equipped with LAF units and separate ventilation and filter systems. The complex is working under negative pressure. The pressure in the pre-chamber is lower than the pressure in the dispensing cell.
The dispensing system enables the filling in open and/or closed vials of different sizes. A rotary plate is positioning the vials under each module of the dispensing system. A syringe pump is transferring the product solution through a sterile filter. Afterwards the vials are automatically dropped into the ventilated bottom lock, in which the activity will be determined as well. The extraction is done directly into a lead container. The lid of the container will be automatically handled.
All vials of a batch are filled consecutively according a
preparation list. The determination of the activity and weight of the bulk solution and the dilution are performed in advance of the dispensing process. Significant parameters are monitored and logged.
Features dispensing system
Automated dispensing process1
Cycle time closed filling < 1 min/vial
Cycle time open filling < 2 min/vial
Solely use of sterile disposable material for all components
which get in contact with the product solution; sterile sets are
available (customized sets with any sterile filter3 possible)
Gravimetric determination of the activity concentration of the
bulk solution; Dilution of the bulk solution and mixing; diluted
product solution with max. 100 ml and max. 590 GBq (F-18)
Activity probes for the determination of the activity of the vials
Activity range: 10 MBq – 50 GBq (F-18)
Dispensing with sterile filtration in open and/or closed vials
(size between 10 ml and 25 ml)2
Maximum batch size 25 vials (10 ml), 24 vials (20 ml)
Dispensing by volume with an accuracy of } 2%4
Bar code reader to trace the pre-labeled vials
Extraction of the vials after determination of the activity directly
in the lead container
