Our expertise

Assembly of complex devices

Sophisticated diagnostic products require careful assembly processes to ensure functionality and reliable results. Based on our flexible modular systems, we always find the perfect technical solution tailored to your diagnostic product.

Microanalysis systems

We offer flexible filling and sealing modules for the production of diagnostic test carrier systems such as lab-on-a-chip or lab-on-a-disc. The reagents are dosed in pipetting stations. In the sealing station, the test carriers are sealed tightly with glue-coated or thermal sealing films.

Handling of lyophilisates

Lyophilized pellets (lyo bead pellets) are ideally suited for diagnostic test carrier systems due to their storage stability. With the Lyo Bead Dispenser, the sensitive pellets can be dosed into the containers with pin-point accuracy, without mechanical stress or electrostatic charging.


  • Diagnostic strip – exact lamination processes

    Precise laminating and punching is important in the manufacturing of diagnostic products made of web materials.

  • Filling small diagnostic test tubes with liquid

    Filling small diagnostic test tubes with liquid and sealing them: Labeling and printing is done in-line.

  • Test Dispenser for detection of allergies.

    Assembly of a diagnostic tool which makes it possible to detect allergies.

Machines and categories


Lab-on-a-chip production for rapid tests

So-called mini labs make it possible to analyze samples at the “Point-of-Care”. Harro Höfliger supplied a filling and sealing station for the production of test elements at Hahn-Schickard in Freiburg.

Gentle handling of lyo bead pellets

For the handling of lyophilisates, Harro Höfliger offers a unique automated solution – the Lyo Bead Dispenser. The freeze-dried pellets are safely conveyed and accurately dosed via air flow.
