Technical information for glass
- Soda Lime Glass: Used for microscope slides due to its surface properties. It has a high linear coefficient of expansion, making it unsuitable for thermal shocks.
- Borosilicate Glass D263: Highly resistant to acids and alkali, suitable for microscope cover glasses. Like soda lime glass, it does not withstand thermal shocks due to its high linear coefficient of expansion.
- Borosilicate Glass 5.1: Offers better resistance to temperature variations compared to soda lime glass and D263.
- Borosilicate Glass 3.3: Ideal for high-quality measuring instruments due to its high resistance to acids and alkali. It has a small linear coefficient of expansion, making it very resistant to thermal shocks.
| Glass Type | Linear Coefficient of Expansion | Hydrolytic Resistance | Acid Resistance | Alkali Resistance |
|---|---|---|---|---|
| Soda Lime Glass | Approx. 9x10-6K-1 | Class 3 | Class 3 | Class 2 |
| Borosilicate Glass D263 | Approx. 7x10-6K-1 | Class 1 | Class 2 | Class 2 |
| Borosilicate Glass 5.1 | Approx. 4.9x10-6K-1 | Class 1 | Class 1 | Class 2 |
| Borosilicate Glass 3.3 | Approx. 3.3x10-6K-1 | Class 1 | Class 2 | Class 1 |

Technical information - Glass Soda lime glass This glass is used for microscope slides for its surfaces' properties. Due to its high linear coefficient of expansion it does not withstand thermal shocks. This glass is highly resistant against acids and alkali and perfectly suitable for microscope cover glasses. Due to its high linear coefficient of expansion it does not withstand thermal shocks. This glass is more resistant to variations of temperature than soda lime glass and D263. This glass is perfectly suitable for high quality measuring instruments as it is highly resistant against acids and alkali. Due to its small linear coefficient of expansion it withstands thermal shocks very well. Soda lime glass Linear coefficient of expansion approx.: Paul Marienfeld GmbH & Co.
