Accurate and repeatable analytical and precision weighing is performed with our laboratory calibration weights. For routine laboratory calibrations or high-accuracy testing, our weights are compliant with OIML, ASTM, and NIST classifications standards.
All your laboratory calibration needs are certified and reliable with top brands we stock such as Globe Scientific, Ohaus, Adam Equipment, Accuris. We also stock calibration weights for milligram-scale analytical balances all the way to 20-kilogram industrial units, in E2, F1, and F2 classess, with and without ISO 17025:2017 Certificates of Calibration.
Calibration weights are imperative for accuracy in laboratory quality control and instrument validation. It enables verification of the accuracy of laboratory balances which needs to be aligned with standards such as GLP, GMP, ISO, and FDA.
Failure to utilize the correct certified calibration weight will result in measurement errors causing unintended consequences like invalid results, dysfunction of equipment, or failed audits. Trusted calibration products by Dawn Scientific help labs maintain precision throughout the calibtation workflow.
From our stock, you can obtain a set of the calibration weights.
As industry requirements dictate, all calibration weights come with a statement of accuracy and, if needed, traceability documents.
Calibration weights are classified to match your instrument’s resolution:
All non ferrous weights are polished free of surface contamination and manufactured from corrosion resistant materials that interfere with the result.
These calibration weights are offered to ISO 17025 accredited facilities because the compliance with the certificate has strict laboratory documented requirements. It documents in detail the national measurement standards, the measurement standards employed, and the temperature conditions, and uncertainty values.
The accredited testing laboratories listed below rely on these calibrated weights directly:

Dawn Scientific carries OIML-certified calibration weights including the 100g weight and 20kg calibration blocks. They are your go-to suppliers for precision calibration tools. Visit their website to view the equipment and ensure that your laboratory balances fetch optimal results and work seamlessly.
Calibration weights are used to verify and adjust the accuracy of laboratory balances and scales. They ensure precise and consistent measurements in analytical testing.
Calibration weights follow standards such as OIML, ASTM, and NIST, and may also be certified under ISO/IEC 17025:2017 for traceability and quality assurance.
These classifications represent OIML accuracy classes. E2 is the most precise, followed by F1 and F2. The class chosen depends on the resolution of the balance being calibrated.
Recalibration is typically recommended annually, but the frequency may vary depending on usage, regulatory requirements, and internal QA standards.
Yes, F1 weights are commonly used for calibrating analytical balances. For more sensitive equipment, E2 weights are preferred due to their tighter tolerances.
We offer calibration weights from trusted brands such as Globe Scientific, Ohaus, Accuris, and Adam Equipment, with a variety of certifications.
Yes, many of our calibration weights include traceability to NIST and come with ISO/IEC 17025:2017 Certificates of Calibration for regulatory compliance.
