Analytical 200g Weight

• Calibration of laboratory balances and scales for accurate mass measurement.
• Quality control in pharmaceutical and chemical industries requiring precise weighing.
• Research and development laboratories for gravimetric analysis.
• Educational institutions for teaching metrology and analytical chemistry.

Nominal mass

This specific unit is 200g. Other analytical weights typically range from 1mg to 20kg.

Material

Commonly made from stainless steel or brass, often with a protective coating.

Tolerance class

For analytical use, these weights typically conform to OIML R 111 standards, such as E1, E2, F1, or F2 classes, indicating their maximum permissible error.

Construction

Solid, one-piece construction is typical for stability and accuracy.

Surface finish

A smooth, polished surface is common to minimise contamination and wear.

Calibration

Units of this type are typically supplied with or require periodic calibration certificates.

• What is the OIML R 111 standard?

  OIML R 111 is an international recommendation for the metrological and technical requirements for weights, covering material, surface roughness, magnetic properties, and conventional mass.

• How often should analytical weights be recalibrated?

• What is the difference between E1, E2, F1, and F2 class weights?

• How should analytical weights be handled and stored?

• Can this weight be used for legal metrology applications?

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.
