Tip ejector adjustment (Fig. 6C)
1. Remove the ejector pushbutton.
2. To increase the ejector length turn the plastic bush to
the left.
3. To decrease the ejector length turn the plastic bush to
the right.
- in 5000 & 10000 μl pipettes
Tip ejector disassembly (Fig. 7A)
1. Remove the tip ejector button
2. Use the screwdriver to turn the metal arbor left to
unscrew the ejector from the arbor.
3. Release the ejector.
Tip ejector assembly (Fig. 7A)
1. Remove the tip ejector button.
2. Use the screwdriver to turn the metal arbor right to
screw the ejector in and adjust its length.
Tip ejector adjustment (Fig. 7A)
1. Remove the ejector pushbutton.
2. Use the screwdriver to increase or decrease the ejec-
tor length.
After ejector assembly or adjustment, put the ejector but-
ton back on its place.
If above described method of ejector adjustment is not
sufficient or the diameter of the ejector opening is too
large to eject the tip it is necessary to put the ejector cap
“M” onto the ejector, (Fig. 7B).
- in 2 and 10 μl pipettes (Fig. 7C)
The 2 μl - 10 μl pipettes may require the use of an ejector
cap "M" to efficiently eject certain brands of pipette tips.
Simply place the cap, supplied with the pipette, on the
bottom of the pipette shaft and slide the cap upwards
until it surrounds the bottom of the tip ejector.
The DISCOVERY Comfort is a high quality instrument
which offers excellent accuracy and precision.
The accuracy and precision of liquid sampling depend on
the quality of tips used. The values for accuracy and preci-
sion given in the table below were obtained using HTL tips.
Only those tips guarantee correct operation of the pipettes
and ensure accuracy and precision of liquid sampling.
ENGLISH
The accuracy and precision are obtained with HTL tips,
using a gravimetric method, performing at least 10 mea-
surements of distilled water at a temperature of 20±1°C,
according to EN ISO 8655 standard.
The pipette design enables the user to perform the
recali bration process according to the rules presented in
section 8.
2 - SETTING THE VOLUME
The volume display shown by the counter has three dig-
its, which should be read from top to bottom. In addition
the lowest counter drum is printed in a scale which
enables the setting of the volume in the minimum gradua-
tion range. Examples of the meanings of the black and
red digits:
