Hanna Instruments HI 731341 Instruction Manual

HINTS FOR ACCURATE MEASUREMENTS
1. Use the pipette in a vertical position whenever possible.
2. Operate slowly and smoothly. Aspiration and dispensing should
been carried-out with the same speed.
3. The tip should be immersed in the sample liquid the minimum
necessary (2-4 mm). Greater depths may cause inaccurate
measures.
4. Change the tip whenever a different kind of sample is to be
aspired or when droplets remain on the inside wall of the tip
from the previous pipetting operation.
5. Work always with samples at room temperature.
PIPETTE MAINTENANCE
1. Liquid should never enter the pipette shaft. To avoid this:
• never use pipette without a tip
• do not invert pipette upside down or lay it flat when there
is a liquid in the tip
• press and release the push button slowly and smoothly.
2. When pipetting concentrated acids or alkalis or corrosive
solutions, pay particular attention to avoid contact of the
liquid with the pipette shaft, or it could be seriously damaged.
Extensive contact with corrosive fumes may result in premature
ageing of internal components of the pipette.
3. After use, store the pipette in its case or in a clean safe
place.
