Pressing and holding the
tip. This function is useful when, for example, you want to terminate the operation
halfway through multiple dispensing.

"Pre-dispensing function" for multiple dispensing

9-9
The electronic pipette aspirates and dispenses a liquid by moving the internal piston
up and down using motor. Since movement of motor and piston reverses when the
operation switches from aspirating to dispensing, an error in dispensing volume due to
backlash will occur. To correct this error, the MPA / MPB series is equipped with the
"pre-dispensing function for multiple dispensing, which automatically discharges a
small amount of sample before delivery. This ensures the piston is always set in the
descending direction when dispensing starts, keeping the margin of error to a
minimum.

Advanced dispensing jobs

9-10
When advanced dispensing jobs need to be done, the following modes on the MPA /
MPB series are available.
１）Dispensing and mixing mode (AUTO+MIX)
By combining Standard mode (AUTO) and Mixing mode (MIX), the device can
proceed to mix after performing the standard operation.
The dispensing amount, number of mixes, and mixing volume can be set
separately.
２）Sequential aspirating mode (SA)
A number of differing liquids can be aspirated at individually set volumes and
dispensed together.
３）Sequential dispensing mode (Sd)
Aspirated liquid can be dispensed sequentially at individually set volumes.
For detailed operating procedures please refer to the supplementary manual for
advanced functions on our website （http://www.aandd.jp/）
Please refer to MPA series (Supplementary manual for advanced functions) on the A&D
website for more information.
