Frequently Asked Questions
1. What is the difference between AR glass and standard clear glass for pipettes?
AR glass (often a high-quality soda-lime glass) is specifically treated to offer improved chemical and thermal resistance compared to basic glass, making it ideal for the rigorous cleaning and reagent exposure typical of lab pipettes.
2. How do I choose the correct graduation scale?
You should select a scale where the smallest graduation (e.g., 0.01ml or 0.1ml) allows you to read the volume with the precision required for your specific measurement.
3. Can these glass graduated pipettes be used with pipette fillers?
Yes, professional glass graduated pipettes like the Hirschmann models are designed with standard top dimensions to fit most manual and electronic pipette controllers or fillers.
4. Are graduated pipettes more accurate than volumetric pipettes?
Generally, volumetric pipettes are more accurate for a single fixed volume, while graduated pipettes provide the flexibility to measure and deliver multiple different volumes using a single instrument.
