A laboratory glass beaker is generally cylindrically shaped with a flat bottom and graduation markers used to store, mix and heat liquids in laboratories. Most also have a small spout (or "beak") to aid pouring. Beakers come in either low-form or tall-form heights. Low-form (or standard) beakers typically have a height that is approximately 1.4 times their diameter. Tall-form beakers are about twice the height of their diameter.
Glass beakers, one of the most common laboratory glassware items, are used to hold, mix and heat reagents.
Exceptional strength and stability. Brilliant transparency. Superior resistance to chemicals, contaminants, and drastic changes in temperature.
