information to be provided for users,
for dilutors with a sample uptake capacity (In) from 5 μl to 10 ml and a diluent capacity (Ex) from 50 μl to 100 ml. They are designed to deliver the sample and diluent together in measured proportion and measured volume.
General requirements and definitions of terms for piston-operated volumetric apparatus are given in ISO 8655-1. The gravimetric reference measurement procedure for the determination of volume is given in ISO 8655-6. Alternative methods for the determination of volume are described in ISO 8655-7. For safety requirements of electrically powered dilutors, see regional or national safety standards.
