Our filling and dispensing heads are the result of years of optimization and are based on a modular design. This allows for quick adaptation to the needs of our customers.

For example, it is possible for our heads to be easily retrofitted later by our customers or service partners.

In addition to, for example, modifications to the fluid or ventilation connections, it is also possible to easily retrofit an additional nitrogen connection, bubble sensors, and more, rather than having to replace the entire high-quality head.

Of course, our filling and dispensing heads are made from high-quality materials specifically designed to meet the requirements of the semiconductor industry.

Through our quality management system, the traceability of components and assemblies is always ensured.

We rigorously test the suitability and reliability of our products on our own test stations before bringing them to market.

In addition to our standard solutions, we offer several special versions as standard. If you require a version that is not currently available or listed, please feel free to contact us.

The handling of the heads is comparatively simple – instructions with helpful tips and recommendations can be found in the information section below.

For most non-flammable inorganic and organic compounds, heads made of PE are typically used.

Heads made of PVDF are primarily used for nitric acid or mixtures containing it.

The information section provides recommendations on the materials.

Connections

The standard connections for media are flare fittings – from 1/4″ to 1″ for PE/PVDF and 1/2″ to 1″ for CD. In addition, we have also developed other connection types, such as Tri-Clamp, Camlock, hose tails, NPT threads, and more, which are standard and usually kept in stock.

Bubble Sensors

Bubble sensors (actually capacitive sensors) detect the presence of conductive liquids, although the requirement for conductivity is relatively low. When a container is empty, the pump starts drawing in air. The resulting mix of air and liquid changes the magnetic field, which can be detected by the (adjustable) capacitive sensors.

Instead of integrating the sensor directly into the head, we have developed a solution that aligns with our modular approach and integrates it into the connection technology (flare nut). This allows our heads to be easily retrofitted in the future as well.

Connection for Nitrogen

Before filling a container, some users first fill it with nitrogen, allowing the existing air to be displaced through the vent connection. Ideally, this nitrogen supply is delivered via the dip tube to the bottom of the container.

Here too, we have developed a component that can be easily “inserted in-line.” This option can also be retrofitted later.

It is also possible to design the nitrogen supply with a check spring that opens only in one direction, preventing any chemical from flowing back into the supply line. However, the same effect can be achieved by maintaining a certain pressure in the nitrogen supply during filling.

Head with a separate sampling port

The modular component for the nitrogen connection is also used as a special solution for sampling. This allows a sample (e.g., via our sampling station) to be taken before the chemical is dispensed through the system.
