Vial Inspection


HEUFT spotter II PHL

Straight complete inspection of larger vials based on the HEUFT SPECTRUM II.

Linear, powerful and fully equipped: even the fillers of large size vials do not have to miss out on the unique combination of superior optics, pulsed X-ray technology and maximum automation in an efficient straight-through system. The HEUFT spotter II PHL carries out a truly comprehensive complete inspection of the sensitive primary packaging material with a capacity of between 20 ml and 1000 ml - and finds quality defects and safety risks such as deviations in filling quantity, glass defects, closure leaks, contamination and foreign matter carefully and precisely. The reliable X-ray detection of minute glass splinters or small pieces of metal is even possible in powders, granules and lyophilised products with active pharmaceutical ingredients (APIs).


Foreign matter detection

Finding everything everywhere: optimal optics and unique X-ray technology.

Hairs, fibres and glass splinters: foreign matter such as this poses a serious threat to the safety of medicinal products. The HEUFT spotter II PHL identifies contaminated vials in good time. High-performance modules carry out the optical inspection of the sidewalls both in the infeed and in the outfeed. A servo-controlled conveyor belt rotates the injection bottles each by 90° in between - their bases are photographed from below at the same time. This ensures that the detection pictures processed and combined by the HEUFT reflexx2 in real time cover the total volume of the large size vials completely. As a result foreign objects are identified everywhere in the container reliably. The linear system can even detect glass splinters or small pieces of metal hidden in powder, granules or lyophilised products - with an X-ray flash module which is easy to integrate for a top-down inspection with unrivalled care and precision. This is also possible with liquid, opaque products such as emulsions and suspensions. The radiation dose of this unique pulsed X-ray technology is so low that the reliable detection of high density foreign objects is even achieved in parenteral drugs with APIs. This protects the integrity of the medicinal product in two ways.

The identification of defects and contamination

Covering everything: continuous all-around inspection.

Chips, cracks and inclusions: the redundant optical modules with high-performance cameras and adaptive LED lighting for a sidewall inspection make such defects and contamination visible everywhere on the sensitive glass container. There are no blind spots because each individual vial is specifically rotated and precisely aligned between the detections. In addition high-resolution images of the complete base area are produced along the way. The result: continuous complete coverage of all the container areas. All glass defects can be detected in this way from chips with loss of material to finest hairline cracks and inclusions. Other flaws such as variations in the product colour cannot escape the continuous all-around inspection with the HEUFT spotter II PHL either. Only clean, perfect full vials with the correct contents reach the patient.


360° closure inspection

Checking the closure integrity: detailed complete inspection.

Correctly positioned, intact and tight: the HEUFT spotter II PHL not only safeguards the functionality of the vial but also the purity and the uncontaminated state of its sensitive contents with a detailed all-around inspection of the flip off closures and crimp caps. The reliable identification of inaccurately positioned, incomplete, incorrectly flanged, dented, defective, leaking and non-brand closures is carried out by two powerful HEUFT FinalView II CAP modules. A continuous all-around inspection is achieved with the correct lighting technologies, optimally arranged, automatically adjustable high-performance cameras and a real-time image processing system capable of learning. The exact alignment of the 20 ml to 1000 ml vials between the two detection stations ensures coverage of far more than 360° in the course of this. In addition the fully equipped vial inspector uses the superior optics for a sidewall inspection in order to examine the position of the stopper with millimetre precision. The respective injection bottles are detected reliably and removed in good time when the stopper is missing, defective or has been positioned too high or too low or varies in colour.

Filling quantity check

Uncovering underfills and overfills: precise inspection of the dose.

Too much, too little or exactly right: it is particularly important with parenteral drugs to have the correct dosage. Each individual injection bottle has to contain exactly the amount of liquid, powder, granules or lyo product which should be in it. No more and no less. The HEUFT spotter II PHL carries out a precise fill level detection in order to determine the filling quantity exactly and to remove incorrectly filled vials consistently. Two X-ray modules have already been integrated in the highly automated linear machine as standard for this. Vials with dosages which deviate from the specification because they are either underfilled or overfilled are therefore identified reliably and removed effectively.

Rechazo de defectos

Disminución de reclamos: el rechazo fiable de envases defectuosos

Rápido, cuidadoso y riguroso: Una elevada precisión es posible, sólo si el producto defectuoso es retirado inmediatamente después de la detección del fallo. Esto lo consigue los rechazos con un único segmento o los sistemas multisegmentos de rechazos pertenecientes a HEUFT.

Easy brand changes

Changing automatically: servo-controlled adjustment of the conveyor belt.

Automatic, fast and easy: the HEUFT spotter II PHL not only carries out a specific rotation and an exact alignment of the containers for an extensive complete inspection with innovative servo technology. In addition it adapts the height and width of the conveyor belt as well as the positions of the cameras exactly to the changed packaging format during brand changes. This is achieved completely automatically due to clearly reproducible brand adjustments. Furthermore this reduces the need for manual intervention, economizes on human resources and not only saves time but money as well: efficiency and productivity losses due to lengthy changeover times are decreased sustainably.

HEUFT rejector

Removing faulty vials: rejecting without compressed air.

Specific, safe and clean: a special rejection system which manages completely without compressed air is included in the scope of delivery of the HEUFT spotter II PHL as standard in order to sort out all the faulty vials in a timely and reliable manner. The HEUFT e-mono has been designed for the safe use in the hygienically sensitive areas of clean room class B. It practically only uses energy at that moment when its rejection segment is extended in order to transport faulty pharmaceutical containers onto a buffer table, a conveyor which runs parallel or to special reject collections points e.g. a container. The HEUFT e-mono can even adapt the advance force of the rejection segment to the weight of the product during the rejection procedure due to its flexible control system. Faulty containers with different filling quantities are therefore always each rejected the same distance.
