The right inspection technology for every product

Is it a particle or just a harmless air bubble? Seidenader Bubble-X detects the difference – with the help of light refraction. 

When inspecting parenteral products, good products are often rejected as defective because the camera cannot distinguish harmless air bubbles from dangerous particles. Biopharmaceuticals, which are usually expensive, are naturally prone to air bubbles. Reduce your number of false rejects — and save millions of euros with Bubble-X. 
 

Cracks and leaks pose as big a risk as foreign objects: They endager the sterility and efficacy of parenterals.

If leaks allow ambient air into a container, pathogens can also intrude. Moreover, the air can alter the active ingredient or even render it ineffective. A pierced needle shield on syringes also compromises the sterility of the product, in addition to posing a risk of injury to medical personnel.  

With high voltage, you can avoid these risks: HVLD stands for our leak detection (High Voltage Leak Detection), HVNSI for the inspection for pierced needle shield (High Voltage Needle Shield Inspection).

Leaks caused by smalest cracks or pinholes are so fine that they cannot be detected even by the best cameras. For containers filled with liquid, we have developed our HVLD: The container is tilted by 90° and rotated to wet the inner wall completely with liquid. It is then moved past electrodes at a small distance. It becomes part of a high-voltage circuit and forms an electrical resistance with the electrodes. If liquid leaks out at any point, this measurably reduces the resistance. Is that the case, the product in question is discharged.
With our HVNSI, you can also inspect syringes for pierced needle shields. A needle can bend and penetrate the cap when the latter is put on. A pierced shield also measurably reduces the resistance, causing the syringe to be rejected as defective.

When the tried and tested high-voltage leak detection system cannot be used due to lack of electrical conductivity of the product, our laser-based Head Space Analysis (HSA) identifies leaks by analyzing the gas composition in the container.

Do you fill freeze-dried products under a protective atmosphere and at negative pressure? Then you know precisely the maximum amount of oxygen that is allowed inside your container. With our HSA, we measure the actual oxygen content present. If the value is above a level defined by you, ambient air has entered the container. The safety of the product is no longer given, the container is rejected.
