What is the significance of 'Class F1'?

Class F1 is an OIML (International Organization of Legal Metrology) standard for calibration weights. It denotes a high level of accuracy and is suitable for calibrating analytical and precision balances.

Is a calibration certificate essential for this type of weight?

While this specific unit does not include one, a current, traceable calibration certificate is typically recommended for Class F1 weights to demonstrate their accuracy and compliance with metrological standards.

How should Class F1 weights be handled?

These weights should always be handled with tweezers or specialised gloves to prevent contamination from skin oils and to avoid scratching or damaging the surface, which can alter their mass.

What is the typical lifespan of a Class F1 weight?

With proper handling and storage, Class F1 weights can last for many years. Their accuracy is maintained through regular recalibration, typically annually or biennially, depending on use and internal quality procedures.

Can this weight be used in a cleanroom environment?

Yes, weights made from high-grade, non-corrosive materials like vacuum-melted stainless steel are generally suitable for cleanroom use, provided they are cleaned and handled according to cleanroom protocols.

Typical context for this category of equipment. Always confirm specifics with the seller.

Used in laboratories for the precise calibration of analytical balances and other high-precision weighing instruments.
Essential for quality control departments in pharmaceutical manufacturing to ensure accuracy of ingredient measurements.
Utilised in research and development settings where highly accurate mass measurements are critical for experimental validity.
Applied in metrology laboratories for maintaining traceability and verifying the performance of weighing equipment.

Weight Class: Class F1, indicating high precision suitable for calibrating balances with a readability down to 0.01 mg.
Nominal Mass: This specific unit is 5g; other units in this class typically range from 1mg to 20kg.
Material: Commonly high-grade stainless steel, often vacuum melted, for stability and corrosion resistance.
Design: Typically a one-piece (monobloc) construction to minimise environmental influence and ensure stability.
Density: For this class of equipment, density is typically around 8000 kg/m³, with tight tolerances to meet OIML R 111 requirements.
Storage: Units of this type are commonly supplied with a protective wooden or plastic box to prevent damage and contamination.

Class F1 is an OIML (International Organization of Legal Metrology) standard for calibration weights. It denotes a high level of accuracy and is suitable for calibrating analytical and precision balances.

Calibration weights and kits are essential for maintaining measurement accuracy across laboratories, biotech and pharmaceutical facilities. Buyers typically prioritise certified traceability, material quality and condition of surface finish when purchasing used sets. Industry sentiment favours equipment from established manufacturers with documented calibration history. Common strengths include durability and long operational lifespan when properly stored. When buying used, verify calibration certificates, inspect for corrosion or damage, and confirm all weights in the set are present and accounted for.
