FAQs of Burette with Straight Bore Glass Key Stopcock:

Q: How is the burette with straight bore glass key stopcock properly used in laboratory settings?

A: To use the burette, securely clamp it upright to a stand, fill to the desired volume using a funnel, ensuring no air bubbles are present. The manual glass key stopcock enables fine adjustment and precise dispensing of liquids, making it suitable for titrations and other volumetric analyses.

Q: What makes borosilicate glass ideal for this burette?

A: Borosilicate glass is chosen for its high chemical resistance, clarity, and durability. It tolerates temperatures up to 200C, enabling repeated sterilization in autoclaves and reducing the risk of thermal shock, which is critical for laboratory reliability and safety.

Q: When should the burette be autoclaved and how does this benefit users?

A: It should be autoclaved before first use and between experiments involving different reagents or hazardous chemicals. Autoclaving sterilizes the burette, ensuring contamination-free usage and maintaining accuracy in measurements for sensitive experiments.

Q: Where can this burette be conveniently mounted or installed during experiments?

A: The burette is designed with compatibility for standard laboratory stand clamps, so it can be easily mounted beside workstations, in fume hoods, or on benches, providing stable support for precision liquid dispensing and hands-free operation.

Q: What process ensures precise liquid delivery from this burette model?

A: The combination of a smooth tapered outlet and a straight bore glass key stopcock allows continuous, controlled liquid release without abrupt spurts. This construction delivers accuracy and repeatability in volumetric procedures such as titrations.

Q: How does the color-coded band system benefit laboratory users?

A: The color-coded bands conform to standard capacity identification systems, allowing technicians to quickly select the correct burette size (10 ml, 25 ml, or 50 ml), minimizing errors and improving workflow efficiency during routine or busy laboratory operations.
