The principles of Good Laboratory Practice (GLP) define a set of rules and criteria for a quality system concerned with the organizational process and conditions under which non-clinical health and environmental safety studies are planed, performed, monitored, recorded, reported and archived.
The European Medicines Agency has a coordinating role for these inspections, whilst the responsibility for carrying them out rests with the Competent Authority under whose responsibility the test facility falls.
The organization of laboratory data is crucial in adhering to GLP standards and maintaining the reliability of research results. Here are some key aspects of organizing laboratory data under GLP:
- Standard Operating Procedures (SOPs): Develop and implement detailed SOPs for all laboratory processes and activities. These SOPs should cover the methods used, equipment maintenance, sample handling, data recording, and data storage procedures.
- Documentation: Maintain comprehensive and accurate documentation for all activities and experiments conducted in the laboratory. This includes raw data, observations, calculations, protocols, and records of any changes made during the study.
- Data Integrity: Ensure data integrity by using secure and controlled systems for data recording, processing, and storage. Data should be protected from unauthorized access and tampering.
- Data Traceability: Establish a system that allows for easy traceability of data from its origin through all stages of data processing and analysis. This includes keeping track of sample identification, instrument calibration, and data transformations.
- Validation and Calibration: Regularly validate and calibrate laboratory equipment and analytical methods to ensure accurate and reliable results.
- Data Archiving: Establish a secure data archiving system that maintains data integrity and accessibility for an appropriate period, as required by regulatory authorities or institutional policies.
- Quality Control and Quality Assurance: Implement quality control measures to identify and correct any errors or deviations promptly. Quality assurance should also involve periodic audits to assess compliance with GLP standards.
- Data Review: Perform a thorough review of all generated data to check for completeness, accuracy, and compliance with study protocols.
- Personnel Training: Train laboratory staff in GLP principles, SOPs, and data handling procedures. This helps ensure consistent and standardized practices within the laboratory.
- Study Director Oversight: Designate a qualified Study Director who is responsible for the overall conduct of the study and compliance with GLP guidelines.
Most of the instruments manufactured by Hanna Instruments have a GLP (Good Laboratory Practice) date feature.
Below, we will present you with some new instruments that are included in our wide range of products and all these instruments have the feature of the GLP option.

HI6421
Advanced Dissolved Oxygen Benchtop Meter with Optical DO Probe (opdo®)
HI6421 is a streamlined benchtop meter with a large touch screen display, comprised of a housing and an integrated module designed for fresh and saltwater measurements of dissolved oxygen.
HI6421 includes Hanna’s HI7641133 optical dissolved oxygen probe (opdo®) that is based on the principle of fluorescence quenching.
An immobilized Pt-based luminophore is excited by the light of a blue LED and emits a red light. As oxygen interacts with the luminophore it reduces the intensity and lifetime of the luminescence.
The lifetime of the luminescence is measured by a photodetector and is used to calculate the dissolved oxygen concentration.

HI6421P
Advanced Dissolved Oxygen Benchtop Meter with Polarographic DO Probe
HI6421P is a streamlined benchtop meter with a large touchscreen display, comprised of a housing and an integrated module designed for fresh and saltwater measurements of dissolved oxygen.
HI6421P includes the HI764833 polarographic probe. Slim and versatile, this probe covers a wide range of dissolved oxygen and has a built-in thermistor temperature sensor that compensates for temperature variations. The slim design allows for convenient measurement in test tubes and Biological Oxygen Demand (BOD) bottles.
