When you run a research lab it's essential to cut costs, without cutting on quality. The Fisherbrand Heavy-Duty Beakers (250ml - Pack of 12) is the convenient and cost-efficient solution to high quality research materials. Using borosilicate glass and a graduated, matte design, this pack ensures accurate readings for any research experiment.

What's Included?

• 12 x Heavy-Duty, Low-Form Beakers

Sizing of the Fisherbrand Beakers

These beakers feature an exterior diameter of 67mm, and 91.9mm height. They hold 250ml of substances.

What Are These Beakers For?

Made of borosilicate glass, these beakers are graduated and designed for a number of different experimental uses.

Key Features 

The Fisherbrand beakers have a number of key features:

• Borosilicate glass is chemical and heat resistant, low coefficient and allows for direct seals
• Evenly tooled top rim for extra wall thickness and uniformity throughout
• Low-form with spout and graduations allows for easy and mess-free use
• Heavy-duty design offers superior durability for mechanized washing and rough handling
• Meet standards ASTM™ Specification E 960, Type II, suitable for laboratory use
• Designed to hold 250ml, these beakers hold liquids and substances for accurate readings
• Graduated design and matte finish increases reading accuracy in lab experiments and research
• Beaker design with wider opening allows stirring of chemicals and substances
• Beakers come in a pack of twelve for cost efficiency and convenience, perfect for all laboratories

Materials

These beakers are made entirely out of borosilicate glass. This type of glass has various benefits important for experimentation:

• Chemically resistant, making it ideal for use with most substances, particularly acids
• Allows high maximum temperatures of up to around 500°C for broad range of experiments
• Cover a wide range of thermal expansions, enabling direct seals with various metals and alloys
• Low coefficient of thermal expansion makes these shatter-resistant under rapid temperature changes

What Are Some of the Other Physical Properties of Borosilicate Glass?

The physical properties of borosilicate glass are as follows:

• Coefficient of expansion (20 to 300ºC):  3.3 x 10^-5/ºC
• Density: 2.23g/cm³
• Refractive index (Sodium D line): 1.474
• Dielectric constant (1MHz, 20ºC): 4.6
• Specific heat (20ºC): 750J/kgºC
• Thermal conductivity (20ºC): 1.14W/mºC
• Poissons Ratio (25 to 400°C): 0.2
