The error limits (Accuracy and Coefficient of Variation) mentioned above 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, the ambient temperature of 20 °C while operating it smoothly and steadily. The error limits are in accordance with DIN EN ISO 8655-5.



The instrument comes with five adapters that comfortably fit most laboratory reagent bottles. The available sizes are – 28 mm, 32 mm, 38 mm, 40 mm and 45 mm.

Extendable Tube

A Telescoping Tube that can be adjusted according to a variety of bottle sizes, is provided as an inside-the-box accessory.
