What Are These Fisherbrand Lab Beakers For?
These Fisherbrand glass beakers are graduated squat form beakers and are designed for general purpose use in chemistry labs. These glass beakers can be used as distillation receiving containers, to hold different layers in an extraction, as reaction flasks, to heat solvent crystallisations, and more.
What Type of Glass Are These Beakers Made Of?
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 a broad range of experiments
- Covers a wide range of thermal expansion, 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% |
| AI2O3 | 2.3% |
| Miscellaneous traces | 0.1% |
Are These Chemical Beakers Certified?
Yes, these Fisherbrand glass chemical beakers are certified to ISO 3819 and DIN 12331. This standard specifies requirements for an internationally acceptable series of glass beakers for laboratory use.
