Burette Calibration in Bangladesh

In modern laboratories, precision is everything. Whether it’s a chemical analysis, pharmaceutical test, or industrial quality control, the accuracy of measuring instruments defines the reliability of results. Among these instruments, the burette plays a crucial role in titration and other analytical experiments. To ensure the highest accuracy, Burette Calibration in Bangladesh has become a vital service for laboratories and industries across the country.

What is Burette Calibration?

A burette is a long, graduated glass tube with a stopcock at its lower end, used for dispensing known volumes of liquid, especially in titration processes. Over time, even high-quality burettes can lose accuracy due to wear, temperature effects, or chemical residue buildup.

Burette Calibration is the process of comparing the actual volume delivered by a burette with the standard reference measurement. Through calibration, users can determine if the instrument is still within tolerance or needs adjustment or replacement. Regular calibration guarantees that every drop dispensed reflects the true measurement.

Importance of Burette Calibration

Accuracy in measurement ensures trust in results. In sectors like pharmaceuticals, food testing, water treatment, and education, even a slight deviation in measurement can lead to major discrepancies. Here’s why burette calibration is essential:

1. Ensures Measurement Accuracy:
   Calibration maintains accuracy within permissible limits, minimizing human and instrumental errors.

2. Compliance with Standards:
   Many industries in Bangladesh must comply with ISO/IEC 17025, BSTI, or other international quality standards that require routine calibration.

3. Supports Quality Control:
   Accurate burettes enhance the reliability of analytical processes, helping laboratories maintain their certification and client trust.

4. Extends Equipment Life:
   Routine calibration and maintenance prevent long-term damage and reduce equipment replacement costs.

5. Safety Assurance:
   In chemical labs, accurate titration ensures safe concentrations and chemical balances during experiments.

Burette Calibration Process

The calibration process involves several precise steps carried out in a controlled environment by trained technicians. Here’s how Pico Labs Ltd. and other accredited calibration laboratories perform burette calibration:

1. Preparation and Cleaning:
   The burette is thoroughly cleaned and dried to eliminate contamination or residue that may affect volume accuracy.

2. Visual Inspection:
   Technicians inspect the burette for cracks, leaks, or scale readability issues.

3. Temperature Control:
   Calibration is performed in a temperature-controlled environment (usually 20°C ± 1°C) since temperature affects liquid density and volume.

4. Filling and Dispensing:
   The burette is filled with distilled water, and measured volumes are dispensed into a precision balance.

5. Volume Comparison:
   The actual delivered volume is compared with the theoretical volume markings on the burette.

6. Calculation of Error:
   Any difference between actual and indicated readings is calculated, and the error is recorded.

7. Issuing Calibration Certificate:
   A traceable calibration certificate is issued, showing measurement data, uncertainty, standards used, and test conditions.

Calibration Standards in Bangladesh

In Bangladesh, calibration services are increasingly aligned with international standards such as:

• ISO/IEC 17025:2017 – General requirements for the competence of testing and calibration laboratories.

• BSTI (Bangladesh Standards and Testing Institution) – Ensures compliance with national and international metrological standards.

• NABL & ILAC Accreditation – For internationally recognized calibration certificates.

Laboratories like Pico Labs Ltd. maintain these standards to deliver reliable and certified calibration services.
