Straight Bore Glass Burette (Class B with Glass Key)

This straight bore glass burette (25ml, Class B) has a glass key stopcock and gives dependable volumetric accuracy in educational and research labs. It meets Class B accuracy standards and pairs a straight bore with a traditional precision-ground glass key. Bold, sharp graduation lines on the clear body make meniscus readings easy during acid-base titrations, chemical assays and precise liquid dispensing.

Key Features

• Class B volumetric precision: Made to standard laboratory tolerances for reliable, repeatable results in student training, routine testing and quantitative analysis.
• Traditional glass key stopcock: A precision-fitted glass key gives smooth manual control for drop-by-drop dispensing and seals airtight when closed.
• High-contrast graduations: Clear, durable markings across the 25ml range let students and technicians record start and end volumes to fractions of a millilitre.
