What are schott duran glasswares?
Schott Duran glassware is a brand of laboratory and industrial glass products known for its high-quality glassware, which includes volumetric pipettes. Volumetric pipettes are commonly used in laboratories for precise measurement and transfer of liquid volumes. The uncertainty associated with volumetric pipettes, similar to other laboratory glassware, is a critical factor in ensuring accurate measurements.
The uncertainty of a volumetric pipette refers to the potential error or deviation from the nominal (stated) volume of the pipette. The level of uncertainty depends on factors such as the class of the pipette and the manufacturer's adherence to international standards.
Here's an overview of the uncertainty associated with volumetric pipettes, typically classified as Class A and Class B:
1. Class A Volumetric Pipette:
Class A pipettes are of the highest quality and precision.
They are designed to meet stringent accuracy standards and are suitable for precise and analytical work in laboratories.
The uncertainty of Class A volumetric pipettes is typically lower, often adhering to international standards like ISO 648 and ISO 8655.
The uncertainty is expressed as a specific value in milliliters (ml) per pipette capacity and is smaller compared to Class B pipettes.
2. Class B Volumetric Pipette:
Class B pipettes have a slightly lower level of precision and accuracy compared to Class A pipettes.
They are suitable for general laboratory work where the highest level of precision is not required.
The uncertainty in volume measurement for Class B pipettes is higher compared to Class A pipettes, as they have a larger tolerance range.
The uncertainty is expressed as a specific value in milliliters (ml) per pipette capacity but is larger compared to Class A pipettes.
The specific uncertainty value for a Class A or Class B volumetric pipette can vary depending on the pipette's size and the manufacturer's adherence to international standards.
When using volumetric pipettes in laboratory work, it's crucial to consider the uncertainty in volume measurement to ensure accurate and reliable results. High-quality glassware manufacturers like Schott Duran typically adhere to these standards to provide users with precise and reliable laboratory equipment.
