For more than 90 years the Glaswarenfabrik Karl Hecht produces high-quality precision devices and glass instruments for
physician and laboratory.

We supply the specialized trade under the well-known trade mark Assistent® through numerous domestic and abroad representatives. Many of them are exclusive distribution partners.

Our comprehensive standard program, e. g. volumetric measuring instruments made of glass and plastics or different liquid handling products, is completed by an extensive range of consumables, disposable articles and electric devices.

Due to our long-time experience and our trained and motivated staff’s professional competence we are the ideal contact
if individual solutions are in demand. On request we are also producing custom-made products even in small quantities.

Since 1995 the quality management system of the Glaswarenfabrik Karl Hecht is certified by TÜV Hessen
according to DIN EN ISO 9001.
The "Assistent" products are distributed worldwide through retail partners (laboratory specialized trade, medical technical specialized trade). Our employees and representatives visit and advise the business partners in Germany, Switzerland, France, Austria and Scandinavia. Thanks to fully developed logistics a fast and reliable delivery is guaranteed. In Germany the supply partly takes place with own vehicles.




The company was founded in April 1919 in Sitzendorf-Unterweißbach (Thuringia) by Mr. Karl Hecht and is engaged in the production and distribution of high-quality precision devices and glass instruments
for physician and laboratory. 

In 1945 the relocation with a new start in Sondheim/Rhön took place
due to the political situation. The branch in Bernhausen near Stuttgart was founded three years later only.

The company extended its present in Europe by additional
sales offices with warehouses:
1962 in Kreuzlingen (Switzerland) - now in Altnau - 1967 in Igny
(near Paris) and 1972 in Fritzens (Austria).
In 1982 the branch in Bernhausen and in 2008 the warehouse
in France were closed owing to better infrastructure.

Sondheim/Rhön became head office and sole production facility.
Currently about 85 employees work here under the guidance
of Mr. Karl-Heinz Hecht and Mr. Thomas Diepholtz.
