ATMOS Functions The ATMOS device offers various functions for daily laboratory work. Apart from the pipette accuracy measurement, it can also support the user with molarity/dilution/serial dilution calculations and offers a standard calculator. All functions are described below. Accuracy Function The accuracy function will measure the accuracy of your pipette. -

RESULT: Measured volume displacement of each measurement. Leak rate: Expressed in volume loss per second. A leak above 0.5%/sec of test volume indicates a leaky pipette, or leaky tip connection (or a bad insertion of the tip into ATMOS port). The following actions are possible: SKIP: This will remove the current measurement. -
