Pasteur pipettes

With the introduction of electric drives on Plastiblow (Plastimac Group) blow moulding machines, their use in the medical field has been expanded. Indeed the elimination of hydraulic drives removes a potential source of product contamination, making it possible to use the machines in clean-rooms or environments with controlled atmosphere.
One application is the production of Pasteur pipettes, a precision laboratory dropper consisting of a thin capillary tube with an engraved scale (normally from 1 to 3 ml) and a larger top part which operates as a pump.
Plastiblow blow moulding machines can produce from 2,000 to 16,000 Pasteur pipettes per hour. For example, the PB2E/S single-carriage model is suitable for intermediate production levels: equipped with a 60-mm extruder and 3-outlet head, it can produce 6,500 pieces per hour.
