VWR 2KG Weight

• Calibration of laboratory balances and scales.
• Verification of industrial weighing systems.
• Quality control processes requiring precise mass measurement.
• Metrology laboratories for maintaining measurement standards.
• Educational institutions for teaching principles of mass and measurement.

Typical capacity

This specific unit is a 2KG weight. Calibration weights are typically available in a wide range from milligrams to multiple kilograms.

Material

Commonly high-grade stainless steel for durability and resistance to corrosion.

OIML Class

Typically available in OIML classes such as E2, F1, or F2, indicating the level of accuracy and tolerance.

Form factor

Cylindrical with a knob for ease of handling is common for this type of weight.

Finish

A high polish finish is typical to minimise surface contamination and magnetic permeability.

Storage

Often supplied with a protective plastic or wooden case for safe storage and transport.

Certifications

Units of this class can be supplied with a Statement of Accuracy or an ISO 17025:2017 Certificate of Calibration for traceability.

• What does OIML Class E2, F1, or F2 mean?

  These classifications refer to the accuracy and tolerance levels of the weight, as defined by the International Organisation of Legal Metrology (OIML). E2 weights offer the highest precision, followed by F1 and F2, suitable for different levels of calibration requirements.

• Is an ISO 17025:2017 Certificate of Calibration necessary?

• How should calibration weights be handled and stored?

• Can these weights be re-calibrated?

• What is the difference between a Statement of Accuracy and an ISO 17025 certificate?

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.
