Laboratory glassware: syringes, volumetric instruments (2nd floor) - German/German
Wertheim experienced an enormous economic upswing in the 1950s. The reason for this was the specialisation in the glass industry that still exists today with the production and further processing of technical laboratory glass. The founding of the "Glaswerk Wertheim" in 1949 was an important milestone. Five glass entrepreneurs from Thuringia thus secured their source of raw materials: Rudolf Brand, Dr. Fritz Friedrichs, Josef Friedrichs, Dr. Hans Löber and Carl Zitzmann. Today, Wertheim is the second largest centre of the German laboratory glass industry after Mainz and before Ilmenau in Thuringia.
One of these first companies to settle in Wertheim, coming from Thuringia, was the company "Walter Graf and Co".
100 years ago, glass syringes were the "big seller" - whether for humans or animals. The demand was enormous and required great craftsmanship then as now - a challenge for Walter Graf when he founded his eponymous company "Walter Graf and Co." with a partner in Schmiedefeld am Rennsteig in Thuringia on 1 July 1923. In 1927, Graf continued to run the company alone and exported his syringes mainly to the USA. In 1950, he moved to Wertheim and purchased the first series production machines just one year later.
A true revolution was the introduction of the brand new technique of calibrating glass tubes in µ-tolerances - i.e. tolerances of 0.001 millimetres. This made it possible to produce the piston and cylinder systems interchangeably: "austauschbar - interchangeable" - as it says on our large glass syringe for animals. In 2000 the company merged with the English company John Poulten Ltd. to form "Poulten & Graf GmbH" in Wertheim and "Poulten & Graf Ltd." in London. Today, they offer a wide range of volumetric glassware as well as manual and automatic dispensers for liquids - but also still the good old glass syringe.

During the 1950s Wertheim recorded an enormous economic upswing. The reason was the local glass industry's decision to specialise in the production and processing of technical laboratory glass. This industry still exists today. The foundation of "Wertheim Glassworks" in 1949 was an important milestone. With this, five businessmen from Thuringia who specialised in glass secured their source of raw materials. These gentlemen were: Rudolf Brand, Dr. Fritz Friedrichs, Josef Friedrichs, Dr. Hans Löber and Carl Zitzmann. Today Wertheim is the second largest centre of the German laboratory glass industry after Mainz and above Ilmenau in Thuringia. One of the first Thuringian companies to settle in Wertheim was "Walter Graf und Co.
100 years ago glass syringes were a "bestseller," whether for humans or animals. Demand was enormous and required then, as it does today, great craftsmanship. This was a challenge for Walter Graf, when he founded his company of the same name "Walter Graf und Co," on 1st July 1923 in Schmiedefeld on the Rennsteig in Thuringia. From 1927 Graf headed the company alone and mainly exported his syringes to the USA. In 1950 he moved to Wertheim and bought the first mass production machines just one year later.
The introduction of the brand-new glass tube calibration technique in tolerances of 0.001 mm was a revolution and it enabled the production of interchangeable flask and cylinder systems. Interchangeable is written on our large syringe for animals. In 2000 the company joined forces with the English company John Poulten Ltd. and became "Poulten & Graf GmbH" in Wertheim and "Poulten & Graf Ltd." in London. Today they both offer a wide range of glass volume measuring gauges, manual and automatic dosing units for liquids and as ever, the good old glass syringe.
