Overview
VWR E-BURETTE is designed for dispensing liquids directly from the reservoir bottle.
It is calibrated in accordance with the guidelines of the DIN EN ISO 8655 – 3.
When the instrument is correctly used, the dispensed liquid comes into contact with only the
following chemically resistant materials: PTFE, FEP and Borosilicate glass.
Error Limits
The error limits (Accuracy and Coefficient of Variation) mentioned in Product Specifications
are in accordance with the nominal capacity (or maximum volume) indicated on the
instrument. These are obtained by using the instrument with distilled water at equilibrium,
ambient temperature of 20 °C, while operating the device smoothly and steadily.
The error limits are well within the limits of DIN EN ISO 8655-3.
