Everything you have to know about scales
When handling scales, weights and other equipment in more challenging conditions, there are a few tips to keep in mind, which we have compiled in a new section called Golden Suggestions.

With scales, we determine mass, not weight.
Weights
- We never unplug the scale from the electric source, we rather use the ‘standby’ function.
- For weighing liquids, we use the smallest possible container and if possible, avoid plastic containers.
- The sample and the vessel should have the same or similar temperature.
- The centre of gravity of the sample should be placed in the centre of the weighing surface.
Weights of accuracy classes E and F
Handling the weights
- Weights of accuracy classes E and F are always stored in a wooden or plastic container, that is padded on the inside.
- Such weights are not to be held by hand but with tweezers, a glove, a cloth or forks.
- We also don’t clean the weights ourselves – we send them to a laboratory to be professionally cleaned and re-inspected.
- If the weight is damaged, it must be sent for rechecking.
For accurate measurements
Space
- The room in which mass measurements are taken should be as vibration-insensitive as possible, so ground-floor or basement rooms are recommended.
- It’s recommended that it only has one entrance.
- Direct sunlight on the instrument must be avoided.
Tips to make your job easier
Weighing table
- The weighing table must be able to withstand as little vibration as possible (preferably granite).
- It must be structurally strong enough.
- It should be reserved for weighing only.
