For dispensing, press down gently on the piston. The automatic lifting action of a spring pushes the piston up. This automatically fills the dispensing cartridge.

The optional flexible discharge tube with safety handle makes it easier to dispense in long series (it connects to the valve block with an adapter).

1. Mount the valve block with filling tube onto the bottle and cover the valve block with cap. Fix the autoclavable sterile membrane filter (0.2 μm) laterally and autoclave at 121 °C.

2. On a Clean-bench (sterile hood), remove the cap from the valve block, screw in a new sterile dispensing cartridge and mount the pump assembly. You’re ready to dispense!
