Innovative „standard products“ & product development

Located in the traditional glass manufacturing area of Thuringia, we develop and produce innovative high-quality products from glass for chromatography, pharmacy and idustry, which are distributed worldwide.

Vials for chromatography

We produce autosampler vials for optimised microsampling with the standard dimension of 12 x 32 mm such as our iV2µ-Vial. This is a 250 µl insert vial which has the insert itself closed by the cap. It is, so to speak, the „little brother“ of our 1.2 ml iV2µ-Vial, which has the shape of a small vase. Both products are our own innovation and are patented.


Vials for optimized microsampling

Custom-made products from tubular glass

Besides producing autosampler vials, we are also your competent partner for custom-made products from tubular glass. Our qualified glassblowers and machine engineers combined with much experience and know how allow us to develop together with you a new product from your idea to serial production.

Example of an in-house design:

Vials with tamper-evident closure (GL 18) and optimised microsampling feature.

The latest product development from GTG unites properties which so far could not be united:

  • Tamper-evident closure
  • Optimised microsampling
  • Made from tubular glass
