Lab Equipment Certification: Maintaining Research Accuracy and Safety

Lab Equipment Certification: Maintaining Research Accuracy and Safety

Summary:


Research accuracy and personnel safety are the two most essential factors in laboratory management. You can achieve these by ensuring regular lab equipment maintenance and certification.


Introduction

Accurate research results and a safe working environment are essential to any successful laboratory. However, accomplishing these objectives involves more than experienced staff and cutting-edge technology. Properly maintained and accredited lab equipment is critical to ensuring the integrity of research results and the safety of laboratory personnel.

Lab equipment certification is essential for ensuring the performance, accuracy, and safety of laboratory instruments and equipment. This article examines the significance of laboratory equipment certification, its benefits, and the procedures for acquiring and maintaining certification.

Understanding the function of certification in preserving research accuracy and safety allows laboratories to ensure the trustworthiness of their data, avoid errors, and safeguard their people from potential hazards.


Why Lab Equipment Certification is Crucial for Research Integrity


1. Protection from Contamination


Equipment certification guarantees that test findings are accurate and dependable by inhibiting the growth of bacteria that can contaminate samples and produce incorrect results.


2. Compliance with Regulations and Standards


Lab equipment certification ensures that your laboratory meets various regulatory requirements, including:

  • ISO 17025: General requirements for the competence of testing and calibration laboratories.
  • FDA 21 CFR Part 11: Electronic records and electronic signature.
  • GLP (Good Laboratory Practice): For laboratories conducting non-clinical studies for pharmaceuticals and other industries.
  • GMP (Good Manufacturing Practice): For laboratories involved in pharmaceutical manufacturing.
  • CLIA (Clinical Laboratory Improvement Amendments): For laboratories performing human patient testing.

3. Ensuring Reproducibility of Results


Duplication of results is an essential aspect of sound scientific research. Certified equipment ensures that results can be duplicated and universal by conducting experiments using standardised protocols and parameters. Regular calibration also ensures that instruments function correctly, providing accurate and reliable data.


Types of Lab Equipment That Require Certification


1. Fume Hood Testing Certification


Fume hood testing evaluates the performance of laboratory fume hoods to ensure they are functioning correctly and providing the necessary protection for users. This involves a series of tests to measure the fume hood’s containment and overall operational efficiency. 

There are three types of fume hood certification testing. They are:

  • Initial Testing: This is performed after the installation or renovation of the equipment.
  • Routine Testing: This is conducted regularly, usually every 6-12 months.
  • Repair Testing: This is done after maintenance or repairs.

Fume hood testing is performed according to industry standards such as:

  • ASHRAE
  • SEFA 1

Widely approved testing procedures include:

  • Visual inspections: Before the test, you must check the fume hood for signs of physical damage, blockage, or obstructions in the airflow path.
  • Airflow measurements: Fume hood airflow measurements involve establishing an average airflow face velocity using a hotwire anemometer. This establishes a baseline for comparison in future testing. Another airflow test is the visualisation test, which uses a smoke test to visualise airflow patterns within the fume hood and in front of the unit.
  • Tracer gas static test: This is used to verify the containment of the fume hood.
  • Tracer gas sash movement effect test: This test verifies the effect of opening and closing the sash on the containment of the fume hood.
  • Alarm and monitoring systems check: All fume hoods must have alarm and monitoring systems that alert users to airflow issues. These systems must be checked and calibrated regularly.

2. Biological Safety Cabinet Certification


Fume Hood Testing

The biosafety cabinet protects laboratory workers and the environment from infectious biological materials. It is field-tested following NSF/ANSI 49, OSHA, NIH/CDC, and the manufacturer’s specifications. These tests are typically conducted when the units are installed, relocated or when HEPA filters are replaced.

Biological safety cabinet certification tests include:

  • Inflow velocity measurements: This test ensures proper inflow is maintained for operator and environmental protection.
  • Downflow velocity measurements: This test documents the air in the laboratory, ensuring it is unidirectional and functioning as designed. It prevents cross-contamination and protects the product from the environment.
  • HEPA filter integrity testing: This test for leakage or defects in the unit ensures that HEPA filters provide the required filtration to prevent product and environmental contamination.
  • Smoke pattern testing: This test verifies the airflow direction using a smoke test.
  • Site installation testing and alarm calibration: This test verifies the alarm system’s calibration and performance and ensures that the units are installed according to NSF and OSHA directions.

3. General Laboratory Equipment Certification


General laboratory equipment certification refers to verifying that laboratory equipment functions correctly, accurately, and safely. This certification is performed by qualified personnel, such as calibration technicians or laboratory managers, using procedures and standards approved by OSHA, NSF, UL, etc.

Some relevant standards and certifications for laboratory equipment:

  • IEC 61010-1: This standard provides the general safety standards for laboratory equipment, such as electrical, mechanical, and thermal dangers.
  • IEC 60601-1: This standard sets the safety standards for medical electrical equipment and its performance in medical contexts.
  • IEC 61010-2-101: This standard establishes the safety criteria for electrical equipment for measurement, control, and laboratory use.

Laboratory equipments that require certification include:

  • Pipettes
  • Autoclaves
  • Microscopes
  • Spectrophotometers
  • PCR machines
  • Centrifuges
  • Balances
  • pH meters
  • Thermometers
  • Humidity chambers
