Glass Burette 50ml with Rota Flow Control

The 50ml Glass Burette is a graduated laboratory instrument used for measuring and dispensing controlled volumes of liquid during titration and quantitative analysis. This STEMAids model has a 50 mL nominal capacity and Rota Flow Control, making it suitable for chemistry, analytical, educational and research laboratory procedures requiring regulated liquid delivery.

Product Description

The STEMAids Glass Burette 50ml with Rota Flow Control is designed for controlled dispensing of liquid during volumetric laboratory procedures. Its graduated burette format enables an operator to determine the volume delivered by comparing the liquid-level readings before and after dispensing.

The nominal capacity is 50 mL. The Rota Flow Control provides the outlet-control configuration specified for this model; its exact valve design and material are .

Key Features

• 50 mL nominal capacity: Suitable for routine titration and quantitative liquid-dispensing procedures.
• Rota Flow Control: Provides the specified flow-control arrangement for regulating liquid delivery from the burette.
• Graduated measurement: Enables delivered volume to be determined from the change in liquid-level readings.
• Transparent glass construction: Supports direct observation of the liquid level and meniscus during use.
• Controlled dispensing: Suitable for dropwise or regulated delivery where required by the analytical procedure.
• Reusable laboratory format: Can be cleaned and reused when chemically compatible with the substances handled.
• Accuracy specification: Accuracy class, tolerance and graduation interval are and should not be assumed.

How to Use the Glass Burette 50ml with Rota Flow Control

1. Inspect the burette, outlet and flow-control assembly 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 air from the outlet where necessary.
5. Read the initial liquid level at eye level using the appropriate meniscus.
6. Operate the Rota Flow Control gradually to dispense liquid at the rate required by the procedure.
7. Read the final liquid level and calculate the delivered volume from the difference between the readings.

Safety note: Wear appropriate laboratory PPE and secure the burette before filling. Never use chipped or cracked glassware. Operate the flow control gently and verify chemical compatibility before handling corrosive or reactive solutions.

Care & Maintenance

• Rinse the burette promptly after use with a cleaning method compatible with the reagent handled.
• Keep the outlet and flow-control passage free from deposits that could restrict liquid delivery.
• Avoid abrasive cleaning that may damage graduations or glass surfaces.
• Store the clean burette securely to protect the tube, tip and flow-control assembly from impact.
