Setting The Volume - HTL LAB MATE Soft Bedienungsanleitung

large to dispose the tip it is necessary to put the ejector
cap "M" onto the ejector, (Fig. 6C).
- in 2 and 10 μl pipettes (Fig. 6D)
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 LAB MATE Soft is a high quality instrument which
offers excellent accuracy and precision.
The accuracy and precision (repeatability) of liquid vol-
ume depend on the quality of tips used. The values for
accuracy and precision given in the table below were
obtained using HTL tips. Only those tips guarantee cor-
rect operation of the pipettes and ensure accuracy and
precision of liquid sampling.

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
recalibration process according to the rules presented in
section 8.

2 - SETTING THE VOLUME

The counter displays three figures to be read from top to
bottom. Additional to the figures on the lower wheel are
printed graduations to enable a volume setting in the
range increment of each pipette model.
Examples of the meaning of the black and red figures:
Pipettes LM2
Red figures at the bottom = 1/100 μl
Increment = 0.002 μl
Pipettes LM10, LM20,
Red figures at the bottom = 1/10 μl
Increment = 0.02 μl
Pipettes LM50, LM100,
LM200, LM250
Black figures only = 1 μl
Increment = 0.2 μl
Pipettes LM1000, LM5000,
Red figures at the top - ml
Increment =
Pipettes LM10000
Red figures at the top - ml
Increment = 20 μl
The volume of the pipette is set by the knob in the pipet-
ting pushbutton (Fig. 1A2) or by the black adjustment
knob (Fig. 1B). To attain the maximum accuracy, set vol-
ume must be approached from a higher value by dimin-
ishing counter readings.
