Automatic Zero Adjustment via Overflow CupThis burette employs an innovative overflow cup system, ensuring that liquid levels automatically reset to zero before each titration. This design significantly reduces human error and increases repeatability, supporting accurate titration results and enhancing laboratory efficiency.
Double Oblique Bore Stopcock 3-WayThe 3-way stopcock, made of durable glass or PTFE, allows for controlled flow and precise delivery of reagents. Its oblique bore structure also minimizes the risk of leaks and provides facile switching between different lines, ideal for multi-step or repetitive laboratory protocols.
ISO/ASTM Compliant, Individually CalibratedEvery burette is manufactured to meet stringent ISO/ASTM standards for laboratory glassware and calibrated individually to Class A specifications. High-visibility printed graduation markings allow precise volume readings and reliable repeatability in everyday lab work.
FAQs of Burettes Overflow Cup,Automatic Zero,Double Oblique Bore Stopcock 3-Way:
Q: How does the automatic zero adjustment work on the burette overflow cup?
A: The automatic zero feature uses an overflow cup to set the liquid level to zero prior to titration. When the burette is filled, any excess liquid flows into the overflow cup, ensuring precise starting volume without manual adjustment.
Q: What benefits does the double oblique bore stopcock provide for laboratory use?
A: The double oblique bore stopcock enables consistent and leak-free switching between lines, offering precise delivery of liquids. Its 3-way configuration is particularly useful for complex titration setups or when alternating between multiple reagents.
Q: When should I use a burette with an automatic zero overflow cup in my laboratory process?
A: This burette is ideal when absolute volumetric accuracy is required, especially for repetitive titrations or experiments where human error in manual zeroing could affect results. It streamlines workflow and eliminates the risk of overfilling.
Q: Where are these burettes commonly used?
A: These burettes are most commonly used in chemical laboratories, educational labs, pharmaceutical analysis, and quality assurance settings where precise volumetric measurements are critical.
Q: What process ensures the accuracy and reliability of these burettes?
A: Each burette is individually calibrated to Class A accuracy and checked against ISO/ASTM standards, guaranteeing systematic measurement precision and consistency batch after batch.
Q: How do I clean and maintain the burette to preserve its calibration?
A: To maintain accuracy, thoroughly rinse the burette with distilled water after each use and avoid any abrasive cleaning agents. Store the burette vertically to prevent stopcock or calibration damage.
Q: What materials make up the burette and its stopcock, and why are they chosen?
A: The burette is constructed from transparent laboratory-grade glass for chemical resistance and clarity. The stopcock is made of glass or PTFE, providing excellent durability and resistance to chemical corrosion, ensuring a long operational life in harsh laboratory environments.
