Glass laboratory equipment and supplies available in our online shop

At Fleischhacker GmbH & Co.KG , we provide access to a wide range of laboratory glass equipment and supplies to suit any need across Germany and internationally. Optimize your processes with our comprehensive range of laboratory glassware. Our selection encompasses steam generators, distillation apparatuses and components. In addition, we offer various stopcocks and valves, vessels, seals, funnels, flasks and other glass bottles.

Our laboratory glassware is made using borosilicate glass.

Unlike borosilicate glass, soda-lime glass is the most common kind of glass and contains about 70% silica. It is typically a softer glass which means it can scratch easily. Pyrex is a chemically strengthened type of soda-lime glass.

Typical substances used to make glass are silicates, borates and phosphates. Borosilicate glass is composed of at least 5% boric oxide, making it more durable and heat resistant. The presence of the boric oxide helps to bind the silicate, aluminum oxide and sodium oxide. This combination of materials means borosilicate glass faces less material stress as it has a lower thermal expansion coefficient. Overall, borosilicate glass is the clear choice for your laboratory glassware needs as it is chemically resistant and resistant to extreme temperature changes.
