Calibrated Glass Burette 50ml

The Calibrated Glass Burette 50ml is a graduated laboratory instrument used for measuring and dispensing controlled volumes of liquid during titration and quantitative analysis. Its 50 mL nominal capacity makes it suitable for chemistry, analytical, educational and research laboratories where repeatable volumetric liquid delivery is required.

Product Description

The STEMAids Calibrated Glass Burette 50ml is designed for controlled delivery of liquid during volumetric laboratory procedures. Its graduated tube allows the operator to determine the volume dispensed by comparing the initial and final liquid-level readings during a titration or related analytical procedure.

The confirmed nominal capacity is 50 mL and the product is identified as calibrated glassware.

Key Features

• 50 mL nominal capacity: Suitable for routine titration and quantitative liquid-dispensing procedures.
• Calibrated burette format: Designed for volumetric delivery using graduated liquid-level readings.
• Transparent glass construction: Allows direct observation of the liquid level and meniscus during measurement.
• Controlled liquid delivery: Supports gradual addition of titrant or other compatible laboratory solutions.
• Graduated measurement: Delivered volume is determined from the difference between initial and final scale readings.
• Reusable laboratory glassware: Can be cleaned and reused when compatible with the substances handled.
• Calibration specification: Accuracy class, tolerance and graduation interval are and should only be stated from verified calibration data.

How to Use the Calibrated Glass Burette 50ml

1. Inspect the burette, graduations, outlet and stopcock for damage or contamination.
2. Mount the burette vertically using a suitable laboratory stand and burette clamp.
3. Rinse or condition the burette according to the analytical procedure.
4. Fill it with the required compatible solution and remove trapped air from the outlet.
5. Read and record the initial liquid level at eye level using the appropriate meniscus.
6. Dispense the liquid gradually at the rate required by the titration or analytical method.
7. Record the final reading and calculate the volume delivered from the difference between the two readings.

Safety note: Wear suitable laboratory PPE and secure the burette before filling. Do not use cracked or chipped glassware. For quantitative work, follow the verified calibration specification and avoid parallax when reading the meniscus.

Care & Maintenance

• Rinse the burette promptly after use with a cleaning method compatible with the solution handled.
• Keep the outlet and stopcock passage free from deposits or crystallized reagents.
• Avoid abrasive cleaning that could damage scale markings or glass surfaces.
• Store the burette securely in a rack or protected cabinet to reduce breakage and calibration damage.
