12. ADJUSTING HEIGHT OF THE TIP EJECTOR
A height of the tip ejector can be
adjusted so that it can match the
conditions of how the tip used was
connected.
Use a small minus screwdriver.
By turning the adjustment screw in
a counter-clockwise direction, the
tip ejector can be lowered toward
the tip side.
13. STORAGE AND MAINTENANCE
When cleaning the outside of the pipette or the tip holder, remove dirt by using a cloth
dampened with 60% isopropyl, 70% ethanol or ph-neutral detergent, and wipe it using
a lint-free and dry soft cloth. Also, because the ejector can easily be removed, the tip
holder can easily be cleaned.
Regularly clean the tip holder about once every half a year to a year, depending on
the frequency used. Regularly confirm the pipette accuracy.
Maintenance
When inspecting the pipette or managing pipette precision, the following device can
be used. (Refer to “17. LIST OF ITEMS SOLD SEPARATELY （ DISPOSABLE
ITEMS）”)
- Leak tester (Sold separately: AD-1690):
Leakage within the pipette can be easily checked.
- Pipette accuracy tester (Sold separately: BM series, AD-4212B-PT, FX-300i-PT):
By using an electronic balance and specified software “WinCT-pipette”, the actual
dispensed amount of the pipette can be confirmed.
