• These Burettes are suitable for use in schools and institutional laboratories not requiring the accuracy of CLASS-A.
• Supplied with NEEDLE VALVE KEY STOPCOCK.
• Scale is durable with ceramic enamel.

Here are potential uses for a Class B burette with a straight bore needle valve key stopcock:

• 1. Titration Procedures:
     • Burettes with a needle valve key stopcock are well-suited for titration experiments where precise control over the flow of titrant is essential. The needle valve allows for fine adjustments, facilitating accurate endpoint determination.
  2. Analytical Chemistry:
     • Class B burettes are commonly used for general analytical work where a moderate level of accuracy is acceptable. The needle valve stopcock provides more controlled and gradual dispensing of the titrant.
  3. Quantitative Analysis:
     • Laboratories performing quantitative analyses, such as determining the concentration of substances in solutions, can benefit from the accuracy provided by Class B burettes with needle valve key stopcocks.
  4. Quality Control Checks:
     • Class B burettes with a needle valve key stopcock can be employed for routine quality control checks in industries where moderate precision is sufficient for the application.
  5. Standardization of Solutions:
     • Burettes with needle valve key stopcocks are suitable for the preparation and standardization of solutions, providing precise control over the volume dispensed.
  6. Education and Training:
     • These burettes are used in educational laboratories for teaching titration techniques and volumetric measurements, offering students practical experience with controlled dispensing.
  7. Routine Laboratory Procedures:
     • Class B burettes with a needle valve key stopcock may find use in routine laboratory procedures where the convenience of a needle valve enhances the control over the dispensing of reagents.
  8. Non-Critical Research Applications:
     • In research settings where a moderate level of accuracy is acceptable, Class B burettes with a straight bore needle valve key stopcock can be used for dispensing and measuring volumes.
  9. Chemical Compatibility:
     • The needle valve stopcock is often made of materials like PTFE, providing chemical resistance and compatibility with a variety of reagents and solutions.
