Class B Graduated Burettes (TD), Glass Straight Bore Stopcock

Every burette is calibrated To Deliver (TD) its specified volume profile by gravity drainage, compensating exactly for the microscopic liquid film left behind along the internal glass tube walls. The integrated straight bore glass stopcock provides classic, highly responsive tactile control over dropwise dispensing, allowing users to secure sharp endpoints. To preserve long-term readability through repeated wash cycles, each tube features permanently baked-in, high-visibility amber graduations that resist fading when exposed to aggressive cleaning detergents or mild chemical acids.

Key Functional Benefits:

• Cost-Effective Class B Accuracy: Manufactured to standard Class B volumetric specifications, providing a dependable, budget-friendly alternative for educational institutions and routine testing benches where Class A certifications are not required
• Traditional Glass Stopcock Control: The ground-glass straight bore key provides classic manual resistance and an ultra-smooth turn radius, making precise, single-drop titrant deployment intuitive
• Durable Baked Enamel Graduations: Stamped with high-contrast amber enamel markings that remain deeply fused to the glass matrix, preventing fading or wearing under demanding chemical sterilization protocols
• Calibrated To Deliver (TD): Calibrated with automated fluid columns to ensure that the volume of liquid dispensed matches the marking readings exactly, minimizing volumetric calculation errors
