When conventional filling technologies in the pharmaceutical industry reach their limits because of fluid viscosity or a stringing effect, the Pharma Dispenser Series of ViscoTec offers an effective solution.
To achieve precise dosing, it is a basic requirement after each successful filling of a packaging unit that the thread must tear off on a defined and clean manner.
This effect is provided with aqueous liquids, although for high-viscosity products, this is rare.
Many products such as creams, gels and ointments pull long threads from the end of the dispensing needle to the particular packaging unit.
Uncontrolled and unwanted dripping of low viscous product from dosing needles can occur with certain parameters. An example of this is a dosing needle with a wide diameter and pressure release over the needle between the shots.
After each dosing shot of the Pharma Dispenser, the path of the fluid is blocked due to chambers inside the rotor-stator combination and dripping of the product is prevented.
A valve inside the dosing needle or pump is not necessary. Due to the reversible direction of rotation a suck back can be adjusted after dosing.
This function helps to obtain an absolutely clean cut of the thread. Volume, speed and acceleration can be individually set according to the requirement of the product.
The thread is precisely cut for highly accurate dosing results. After each filling, process edges of the packaging or parts of the filling machine will not be soiled or contaminated with the product.
