No more bad vials in your glass production!

Isotronic provides in industrial image processing solutions for quality assurance of pharmaceutical glass vials in production. Originally founded as a pin off of a glass manufactura 30 years ago and updated in 2018, Isotronic ensures many years of experience and passion.

Our high quality and proven products are the result of dealing with variance of raw material and complex production conditions. With over 500 sold systems in more then 20 countries we want to support companies to simplify internal coordination, help to reduce waste for ecological reasons and most important:
ensure the beauty and aesthetics of vials!

Image Processing Solutions

We deliver an integrated solution consisting of hard- and software. This usually consists of an industrial PC in a control cabinet with industrial cameras, lenses, illumination, and mechanical sensors including in-house developed image processing software.

DC Measurements

Our VialChecker software performs real time evaluation of vials in production. It is highly configurable to adapt certain production process needs.

Dimensional Checks

Geometry checks are the basis for QA in production process. We provide checks for threaded and/or injections vials, bottom and bottom base checks as well as customer specific requirements like pipette tip measurements.

Our software is capable of checking a variety of more than 50 dimensional measures.

Cosmetic Checks

The demand for cosmetic inspection rises especially in pharmaceutical industry but starts to be an important quality criterion in similar industries like lab suppliers as well. Isotronic provides cosmetic inspection capabilities either as integrated part of geometric inspection (for simple tasks) or as separate system for more challenging tasks.

We provide surface inspection for bottom, body, shoulder, neck, head and opening including classification of defects.


Depending on the optics used accuracies of 1/1000mm for dimensional checks and 1/100 for cosmetic checks is possible. We use subpixel-based algorithms for increased stability.


Depending on handling speeds > 100pc/min are possible


Production certificates and productions insight are crucial for proving compliance to quality requirements. Measurement systems for the whole production facility can be monitored in a centralized fashion, as well as viewing and printing of production certificates.


All production data for a production facility can be stored in a SQL-compatible database. Our software uses this DB for evaluation and production insight. We also provide full access to the raw data for further analysis and/or integration by the customer.
