![]() This assumption / anticipated probability was based on other recent testing I had done of an actual scientific beaker (newly manufactured / recent product). The Legend of Bohemian Glass: A Thousand Years of Glassmaking in the Heart of Europe. Ma Saturday When I purchased this Beaker from the OMSI gift store I was nearly certain it would test positive for Lead in the exterior painted markings. Jena Glass and Its Scientific and Industrial Applications. “The Attack of Chemical Reagents on Glass Surfaces, and a Comparison of Different Types of Chemical Glassware.” Journal of the Society of Glass Technology 1 (1917): 153–62.

Jena Glass quickly became a success among the scientific community, widely considered the best on the market until World War I. Their strength against chemical attack and low coefficient of thermal expansion made them better suited to the harsh circumstances of the chemical laboratory than any other glass. As their research expanded, they eventually developed the first borosilicate glasses. Borosilicate Glass Beaker 2 Pack 400ml Laboratory Glassware Boro 3.3 Low Form Easy to read graduations and marking area Beakers feature a 400ml capacity. Their original goal was to develop glasses of high quality and purity with consistent optical properties. Together they hoped to perfect a chemical glass formula for lenses in optical instruments like microscopes and telescopes. Choose the right size for your lab needs, ranging from 50 ml to 2000 ml. ![]() In 1881 Schott, a chemist from a family of glassmakers, and Abbe, a physicist with an interest in optics, formed a research partnership. Pyrex® beakers are the science industry standard worldwide. For some experiments I have made concentrated sulfuric acid. This example was made by Schott & Genossen in Jena, after 1884. 1000 ml low grade pyrex beaker - This is a very good quality beaker. It does not store any personal data.In chemical parlance, a beaker is a cylindrical vessel, usually of glass, with a flat bottom and a small beak (or pouring spout).
