The air passes through a silicone tube with an inner diameter of 5 mm (5×8 mm). The Hepa-filter
prevents contamination of the sterile immobilization mixture and should be replaced according to the
manufacturer’s instructions or if signs of reduced air passage are noticeable.
The liquid passes from the inside of the bottle through a PTFE tube (3×6 mm) to the silicone tube 
outside of the bottle. This silicone tube is attached to the bead producing unit with the luer lock male .
