Blow fill seal ampoule inspection



A one hundred percent all-around inspection of pharmaceutical blow fill seal ampoule strips based on the HEUFT SPECTRUM II.

The straight-line HEUFT spotter II BFSA has been specially developed for the all-round inspection and integrity testing of primary packaging materials for small volume parenteral products and other liquid preparations which are produced using the blow fill seal method and achieves complete reliability when detecting and rejecting faulty plastic ampoules. They identify deformations, missing or excess packaging components, soiling, scratches, scores, inclusions and cosmetic defects in the container material just as reliably as foreign particles, fill quantity and product colour deviations inside them.


Cap inspection

Ensure closure integrity: Top-down and all-around inspection.

Cosmetic defects, missing or misaligned components: The HEUFT spotter II BFSA detects closure faults such as these during the top-down inspection of filled blow fill seal ampoules. Inclusions such as black spots but also material shortages and excesses, scratches, damage and deformations on the closure as well as misaligned closures are reliably identified during the inspection of bundled ampoule strips using smart LED illumination and specially adapted camera, image filtering and subtraction technologies.


Sidewall inspection

Covering everything: Alternating complete inspection.

Damage, cosmetic defects, foreign particles and fill level deviations: A full coverage inspection of the sidewalls of blow fill seal containers is essential in order to find such faults everywhere. The HEUFT spotter II BFSA realises this with sophisticated optomechanics and a specially designed transport device:


the servo-controlled belt drive which clamps the ampoule strips and guides them straight through the device has an alternating design. In the infeed, they are "gripped" at the top to examine their entire lower part down to the bottom edge, and in the outfeed, they are then gripped at the bottom so that the entire upper half is covered there. This not only creates redundancy and thus even more detection reliability during closure inspection, but also realises complete coverage of the full volume of each individual primary packaging for small volume parenterals. From missing or excess closure components to inclusions, contaminants or inconspicuous fat deposits to fill level and product colour deviations, floating foreign particles and base deformations, all critical defects are detected regardless of their location and position.



Base inspection

Getting to the bottom: Seamless inspection of the underside.

Foreign particles, inclusions, contamination and damage: To find such defects in every case, the full-cover sidewall inspection down to the bottom edge is not always sufficient. Additional safety is provided by another high-performance camera that scans the container base. This reliably identifies foreign particles that have sunk to the bottom of the container, but also black spots trapped in the base, contamination and deformations of this area. Together with the full-coverage sidewall inspection, this ensures that the entire base - including its underside - is inspected without any blind spots.


Fault rejection

Preventing recalls:  the reliable rejection of faulty containers.

Fast, careful and accurate:  highest precision when detecting faults is only effective if the products in question are also removed afterwards.  The single-segment and multi-segment rejection systems of the HEUFT rejector series deal with this both precisely and carefully.

Simple type changes

Automatic changeover: Servo-controlled adjustment of the detection and transport units.

Automatic, fast, simple: as is usual with systems based on the HEUFT SPECTRUM II platform trigger photoelectric sensors, cameras, lighting units and transport devices adjust themselves fully automatically to different sizes and types of blow-fill-seal containers. Programme and format changes can thus be carried out without tools and without any human intervention. This not only saves time, but also money: efficiency and productivity losses due to lengthy changeover times are sustainably reduced.

Product monitoring and self-tests

Playing it safe:  exact product tracking and regular self-tests.

Always knowing the current location of a particular product:  each one is tracked precisely for this.  This ensures that none remain uninspected.


The integrated reject verification checks that each product identified as faulty is really removed.  Standard test programs guarantee a regular examination of the detection performance.  Network-based continuous documenting and long-term archiving of the results.




Simply automating:  universal device platform for maximum performance.

Highly automated, universal and powerful:  the HEUFT SPECTRUM II ensures optimum detection and operational reliability during an in-line quality assurance for the sustainable safeguarding of product quality and line efficiency.


The cross-system control unit with multiprocessing capability for different modules, systems and applications convinces due to its exceptional degree of automation.  Brand and format changes can be carried out without manual intervention.  The unique human machine interface of the universal device platform is self-explanatory.  Human resources are effectively saved in this way.  In-house developed hardware and software of the latest generation and a future-proof network connection achieve highest computing power and data transmission in real time.  The result:  maximum precision during purposeful product tracking, inspection and rejection.

Simply detecting more:  real-time image processing with individual teaching in procedure.

Fast, high-resolution and smart:  the new generation of in-house developed hardware and software for image processing provides four times the processor speed of its predecessor.  It converts the images of the individual camera or X-ray units into high-resolution, noiseless detection pictures in real time.


At the same time the HEUFT reflexx A.I. not only carries out the specific detection of the most varied objects but also their individual classification using up to 50 different characteristics such as size or texture:  uncritical characteristics can be quite simply taught in as good objects.  The containers in question are therefore no longer rejected.  Only that which really has to be removed is rejected.  This reduces the false rejection rate and upholds the efficiency and productivity of the complete filling line.

Simply knowing what to do:  self-explanatory audiovisual user guidance.

Intuitive, individual and audiovisual:  previous knowledge is not required in order to operate the HEUFT SPECTRUM II systems reliably.  The HEUFT NaVi user guidance is self-explanatory and supports the respective user step by step.


An RFID login with user-related access rights provides an overview and makes the respective user's work simply easy:  he only sees what he really needs to on the clearly arranged touchscreen user interface with a flat menu structure, integrated tutorials and precise auxiliary tools in order to fulfil his specific tasks optimally.  He is supported by a virtual assistant in the course of this.  She speaks to him and clearly explains what has to be done when and where.  Purposeful and focussed on the essentials – the audiovisual HEUFT NaVi user guidance makes the reliable operation of HEUFT systems simply easy!



HEUFT checkPoints

Simply seeing where what has to be done:  trouble-free localisation.

Clear, direct and purposeful:  the user can cope immediately on the rare occasions when manual intervention is needed.  Because eye-catching HEUFT checkPoints make it clear at a glance exactly when it is necessary to take matters in hand in addition to the audiovisual information which the HEUFT NaVi provides.


The orange tags not only flash on the touchscreen but also at the respective component if the worst comes to the worst.  The problem is located without a long search.  This saves time and human resources, shortens standstills and therefore increases productivity.

Network technologies

Simply capture everything: Network connectivity for performance analysis and audit trail documentation.

Computer-aided systems for the packing and quality assurance of pharmaceuticals must fulfil strict requirements and documentation obligations. This is another reason why HEUFT devices are network-capable. With user-related access rights and a detailed audit trail log of all operating and process information they fulfil the FDA's 21 CFR Part 11 requirements. This protects against unwanted parameter changes and makes all logins permanently traceable. An online connection to higher-level databases and MES systems ensures real-time transmission, processing and complete archiving of detection images, batch and production data as well as reliable audit trail documentation. There is a network connection to the HEUFT TeleService for reliable remote diagnosis and maintenance.


Linear construction

Run in a linear way: Compact straight-forward system.

In addition to its functionality and automation the HEUFT spotter II BFSA is distinguished above all by its consistent linear operation. This makes it extremely compact, enables fully automatic sort and product changes and reduces storage costs. In addition it is ensured that the sensitive BFS containers are handled gently with the highest possible throughput. After all, they are supposed to detect defects instead of producing them themselves. Specially designed conveyors ensure gentle handling of the space-saving straight runner.

HEUFT CleanDesign

Cleaning quite simply:  hygiene-optimised construction.

Accessible, clean and safe:  its HEUFT CleanDesign predestines the system for use in hygienically sensitive areas.


Sloping surfaces facilitate cleaning and prevent the accumulation of stubborn dirt.  Special channels and openings allow the liquids required for cleaning purposes to be drained off completely.  Consequently dangerous germs and bacteria have no contact surface whatsoever.  Specially constructed casings and doors create optimum accessibility.  The electronics are totally encapsulated.  Sensitive areas such as the inspection units are dust-proof and protected against contact as well as water jets.

Sorting out faulty BFS containers: Accurate rejection.

Targeted, safe, reliable: Different single or multi-segment rejection systems can be connected to the HEUFT spotter II BFSA in order to remove individual or bundled blow-fill-seal ampoule strips which have been detected as faulty from circulation in good time. They consistently remove pharmaceutical blow-fill-seal containers with safety and quality defects from the production flow so that only faultless ones reach the patient.
