Mass & Volume Calibration
Accreditation Number: 1455
Balance Calibration Services & Measuring Instruments
Measuring up to the Highest Standards
Our laboratory support team can assist with balance calibration services as well as the calibration of measuring instruments such as pipettes. It is our mission to leave no room for error and to ensure our services hold up to the highest standards. With our vast industry experience, assisting laboratories all over South Africa, and with our team of highly-skilled technicians, we have become known as leading calibration company in the country.
SANAS Accredited Services
Our Mass & Volume Calibration Covers:
For all of our balance calibration services and testing the following “Metrological Tests” are carried out: Repeatability, Eccentricity and Linearity (unless user or client has requested partial calibration – where in that case it must be documented on calibration certificate).
These individual tests may differ very slightly on different types of equipment but the principle remains the same.
Pipettes and Glassware
Glassware and pipettes volume measurement is an important step in most industrial and analytical measurement operations. Volume instruments are used in many fields like chemistry, health, biology and pharmacy. Laboratories must ensure that results obtained using these instruments are reliable.
In order to reduce and identify possible errors in liquid handling, it is necessary to calibrate volume instruments using the correct methods.
At the highest level of the traceability chain, the volume can be determined by the primary method of weighing the contents of a suitable liquid, by known temperature and density (gravimetric method) and by weighing the amount of water delivered by or contained in the volumetric apparatus.
The mass is then converted to the desired volume using the tabulated density of Water:
Volume = mass / density
Pipettes – Calibration points are a 10, 50 & 100% of pipettes range with adjustments made at 50%. Pipette service is an optional extra where we strip and clean the pipette and carry out routine maintenance including cleaning, stripping and lubricating piston. Note: Customer to provide pipette tips and necessary adjustment tools. Customer to acknowledge pipettes have been sterilised prior to calibration.
