Calibrated Glass Burette 50ml

Quick Answer

This 50ml calibrated glass burette has a graduation scale checked for accurate volume delivery, making it suited to quantitative titrations where the exact amount of titrant added directly affects the analytical result.

Description

A burette’s usefulness in quantitative work depends on how reliably its scale reflects the true volume dispensed, which is what “calibrated” refers to here: the etched graduation scale is manufactured and checked for accurate volume delivery rather than being a rough estimate of length along the tube. A glass stopcock at the base controls the flow, letting the operator add titrant as a steady stream or slow it to single drops as the titration approaches its endpoint.

At a 50ml capacity, this burette covers the great majority of standard titrations carried out in analytical and teaching laboratories, and its full-length scale allows the volume to be read accurately at any point during the procedure, not only at the very end.

Care & Handling

Mount the burette vertically in a stand and check it is level before starting a titration
Check the glass stopcock turns smoothly and does not leak before use
Always read the meniscus at eye level, using the same viewing angle each time, to keep readings consistent
Rinse the burette with the titrant solution before filling for the titration
Clean and dry the burette thoroughly after use to protect the accuracy of the calibration over time

Frequently Asked Questions

What does “calibrated” mean for a burette?

It means the graduation scale etched on the burette has been manufactured and checked for accurate volume delivery, so a reading taken at any point on the scale reflects the true volume of liquid dispensed.

What is a calibrated burette used for?

It is used mainly for quantitative titrations, where the exact volume of titrant delivered is used to calculate the concentration or amount of a substance in the sample being analysed.

How accurate is a calibrated 50ml burette?

A calibrated burette is designed to deliver volumes that closely match its printed scale, though the precision of any individual reading also depends on correct technique, including reading the meniscus at eye level and controlling the stopcock smoothly.

How do I keep readings consistent between titrations?

Read the meniscus from the same eye-level position each time, take both an initial and final reading for every titration, and rinse the burette with titrant before each fill so residual water does not affect the result.

Does the stopcock need maintenance?

Yes, the stopcock should be checked periodically to make sure it turns smoothly and seals without leaking, and it should be cleaned after use so residue does not build up and affect the flow.
