Beakers
LabDirect's range of glass laboratory beakers is essential for all busy labs. They are perfect for mixing and heating liquids or for general sample containment. Our beaker glass is borosilicate high-temperature glass, which makes our glass beakers ideal for use on top of a hot plate or over an open flame.
Beakers are available in short or tall form and in SUPER DUTY for enhanced strength with thicker glass walls. Beaker sizes range from 50ml to 10,000ml in volume. White fired enamel graduations are also available on all beakers for approximate liquid measuring.
LabDirect stocks glass beakers from PYREX and ISOLAB, two world leaders in laboratory glass manufacturing. The brand stamp appears on all beakers.

FAQs
What is a glass beaker, and when should I use one?
A glass beaker is an open-topped cylindrical vessel used for mixing, heating and holding liquids. It’s ideal for general lab tasks such as preparing solutions, gentle heating or temporary sample containment.
What is the difference between a low-form (short) beaker and a tall-form beaker?
Low-form (short) glass beakers are wider and better for stirring, heating and general mixing. Tall-form beakers are narrower, reducing evaporation and splashing, and are useful for reactions requiring more controlled heating.
Why choose borosilicate glass beakers instead of regular glass?
Borosilicate beaker glass offers superior thermal and chemical resistance, making it far safer for heating, cooling and handling reactive substances. Regular glass can crack or shatter under temperature change.
Can I heat a glass beaker directly on a hot plate or Bunsen burner?
Yes, borosilicate glass beakers are designed for direct heating on hot plates and can withstand open-flame exposure when used correctly. Avoid rapid temperature changes to prevent thermal shock.
What is a conical beaker, and what are its advantages for mixing or heating?
A conical beaker has sloped sides that minimise splashing and improve heat distribution. Its shape also makes swirling and mixing easier without using a stir rod.
What safety precautions should I take when using glass beakers?
Use heat-resistant gloves, avoid sudden temperature shifts, never heat cracked glass beakers and place hot beakers on heat-safe surfaces. Handle large volumes with care due to added weight.
Are the graduations on beakers accurate for measurement?
Beaker graduations are approximate only. For precise measurement, use calibrated cylinders or volumetric glassware.
How do I properly clean and maintain glass beakers to ensure longevity?
Wash with laboratory-grade detergent, rinse thoroughly and avoid abrasive scrubbing that can weaken the beaker glass. Allow heated beakers to cool gradually before washing.
