OIML F1 Calibration Weights, 1 mg to 20 kg

Description

The OIML F1 Calibration Weights, also known as F1 class balance calibration weights, are precision-engineered reference masses designed to support accurate weighing verification across laboratory, industrial and educational environments. They are used where consistent and traceable mass standards are required to confirm the performance of analytical balances, precision balances and industrial weighing scales. These calibration weights are manufactured to OIML F1 tolerances, making them suitable for routine calibration checks, intermediate verification steps and general quality control procedures where high accuracy is required but not at the strictest metrology class. They provide a dependable reference point for ensuring weighing instruments remain within acceptable performance limits.

The available capacity range extends from ultra-small milligram values (1 mg) through to high-capacity 20 kg weights. This broad selection allows users to perform multi-point calibration routines across a wide variety of instruments, from microbalances and analytical balances through to platform scales and industrial weighing systems. This flexibility makes the F1 range suitable for both laboratory and production environments. Each weight is manufactured from high-grade stainless steel, providing excellent resistance to corrosion, wear and environmental exposure. This ensures long-term stability of mass and reliable performance even under frequent handling conditions. The material also supports easy cleaning and maintenance, which is essential in regulated laboratory environments.

The F1 class density of 7.9 g/cm³ contributes to consistent physical properties across the range, supporting repeatable measurement outcomes when used in controlled calibration procedures. This consistency is important for maintaining traceability and ensuring reliable comparison against certified reference standards. To protect accuracy and surface integrity, individual weights are supplied in impact-resistant plastic cases. These cases help prevent contamination, scratches and handling damage during storage and transport. Where sets are supplied, they are housed in a lined aluminium storage box designed for organised arrangement and long-term protection. Forceps and white cotton gloves are included where applicable to minimise direct contact and reduce the risk of contamination during handling.

These calibration weights are widely used in scientific laboratories, pharmaceutical facilities, quality assurance departments, manufacturing environments, materials testing laboratories and educational institutions. They are particularly valuable in workflows where routine balance verification and compliance with internal or external quality standards is required. Users should ensure they select the correct OIML class and weight configuration for their specific application. It is also important to confirm whether a calibration certificate is required, as well as compatibility with the intended balance or scale, including readability, capacity and internal calibration functions. Proper handling procedures and storage conditions should also be observed to maintain long-term accuracy. This product is supplied as the selected OIML F1 calibration weight only. Balances, scales, calibration certificates, accessories and additional equipment are not included unless specifically stated.

LabChoice Australia supplies OIML F1 Calibration Weights to support reliable weighing verification across school laboratories, universities, research facilities, pharmaceutical environments, QC laboratories, materials testing centres and industrial operations requiring dependable reference mass standards.
