Everyday laboratory glassware: These low-form beakers are made of borosilicate glass, the standard material for laboratory beakers because of its strong resistance to thermal shock and chemical attack. The low-form shape, with a height roughly 1.4 times the diameter and a small pouring spout, is the general-purpose workhorse of the laboratory: stable on the bench thanks to its wide base, easy to pour from, and suitable for the everyday tasks of mixing, dissolving, heating, and holding liquids across a huge range of applications. Why borosilicate glass: Borosilicate withstands rapid temperature changes far better than ordinary soda-lime glass, which is what allows these beakers to be heated on a hot plate and used with reagents that would attack lesser glass. Its combination of thermal and chemical durability is the reason it became the laboratory standard. Just as important, the glass is transparent, so you can watch a reaction proceed, judge mixing, check for undissolved solids, and read the printed graduations against the contents. Three sizes for different scales: The group includes 50 mL, 250 mL, and 600 mL capacities, spanning small-scale bench work through larger-volume preparation. Choosing a beaker close to the working volume keeps the printed graduations useful for approximate measurement and reduces the risk of overfilling or splashing. Having several sizes on hand lets a laboratory move smoothly between titrations and small preparations and the larger mixing and dilution steps that need more room. Practical, dependable performance: As with all beakers, the graduations are intended for approximate volume estimates rather than precise measurement, so a graduated cylinder, volumetric flask, or pipette should be used where accuracy matters. Used within their intended role, borosilicate low-form beakers are among the most reliable and frequently reached-for items in any laboratory, standing up to routine washing and repeated heating cycles while remaining clear and easy to inspect.
