12.0 Tip Ejector Height Adjustment

in a counterclockwise direction, the tip ejector can be adjusted down. This height adjustment feature enables efficient ejecting of
different manufacturers' tips.

13.0 Maintenance

The outside of the Labnet Excel™ electronic pipettor may be wiped clean with 60% isopropanol, 70% ethanol, or mild detergent, and then
wiped dry with a lint-free cloth. If the pipettor is severely contaminated or if very corrosive chemicals are dispensed, the lower part of the
Labnet electronic pipettor should be disassembled. The individual parts should be rinsed in distilled water and then air dried.
It is recommended to clean the Labnet Excel electronic pipettor at regular intervals depending on how much the pipettor is used, as well
as lubricating it once per year. If the pipettor is autoclaved often, you may need to lubricate the pipettor more frequently. Lubrication of
the piston should be performed only by authorized Corning representative, and only the proper Labnet Excel electronic pipettor lubricant
available from Labnet should be used. For more information on the proper service of your Labnet Excel electronic pipettor, contact your
Corning representative.
It is recommended to check the performance of your Labnet Excel electronic pipettor regularly (e.g., every 3 to 6 months) and
always after maintenance or service. More frequent testing of the Labnet Excel electronic pipettor may be desired depending upon
requirements of the application, frequency of use, number of operators using the pipettor, nature of the liquid dispensed and the
acceptable maximum permissible errors established by the user (ISO 8655-1). For more information on Labnet Excel electronic pipettor
calibration procedures, contact Corning Customer Service.
NOTE: Using improper lubricants may deter or block the movement of the Labnet Excel electronic pipettor's piston.
