Frequently Asked Questions
1. What does the "Assistent-Permanent" graduation refer to?
"Assistent-Permanent" is a proprietary high-contrast marking (often in brown or blue) that is fused into the glass surface, making it exceptionally resistant to laboratory chemicals, detergents, and high-temperature cleaning.
2. Are Karl Hecht glass coverslips suitable for high-resolution microscopy?
Yes, their cover glasses are manufactured from premium, colorless borosilicate glass (D 263® M) according to ISO 8255, offering excellent flatness and optical clarity without distortion.
3. How does Karl Hecht ensure the accuracy of its volumetric instruments?
Each volumetric device is carefully adjusted and tested in-house. Depending on the model, they are manufactured to Class A or Class B tolerances and can be supplied with batch or individual certificates of conformity.
4. Can I use Karl Hecht borosilicate 3.3 glassware in a microwave?
Borosilicate 3.3 is microwave-safe due to its low dielectric loss. However, avoid heating sealed containers or using items with metallic graduations unless otherwise specified.
