Beakers and Accessories
Laboratory beakers, usually made from glass or plastic (and less commonly from metal) are found in most chemical, biological, clinical and industrial laboratories and a variety of other workplace settings.
Laboratory beakers are vessels that are distinguished from flasks by generally having straight, rather than sloped sides, although stackable beakers may be slightly tapered for efficient storage. Beakers have a flat bottom and are cylindrical in shape. Most have a spout to aid pouring.
Laboratory beakers are typically available in a range of capacities from 5mL up to 10L. Most beakers feature printed or moulded graduation lines, although these marks are not intended for precise measurement.
Plastic beakers are manufactured from polypropylene, HDPE (polythene), PMP (polymethylpentene), polycarbonate or PTFE. Plastic beakers are popular for general use and minimise the risk of breakage.
Glass beakers are manufactured from borosilicate or soda lime glass, and generally offer greater longevity, all-round chemical resistance and autoclavability.
Metal beakers are made from aluminium or stainless steel and offer exceptional heat and fire resistance. Metal beakers will not shatter or chip in use.
Laboratory beakers are also offered in a choice of styles depending on the intended application:
- Low form beakers (also known as short form beakers or Griffin beakers) are less prone to accidentally knocking over and so are widely used for a range of purposes
- Tall form glass beakers (or Berzelius beakers) are popular for use in titrations
- Heavy duty beakers, with thicker-walled glass and reinforced rims, can withstand more rigorous and demanding use
