What Are the Fisherbrand Heavy-Duty Low Form Beakers For?
Made of borosilicate glass, these heavy-duty beakers have a low-form style and feature a sturdy construction that is ideal for mechanical shock and other harsh applications. A spout is also included on these beakers for optimum performance.
What Are These Fisherbrand Lab Beakers Made Of?
These Fisherbrand lab 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
What Is The Typical Chemical Composition of Borosilicate Glass?
Below is a table demonstrating the typical chemical composition of borosilicate glass (% by weight):
| Component | Percentage (approx.) |
| SiO2 | 80.6% |
| B2O3 | 13.0% |
| Na2O + K2O | 4.0% |
