3. MINILAB SET-UP
Inserting the syringe
• Push the filling slide (3) right down to the stop.
• Push the stopping lever (4) upwards.
• Exert a slight pressure to insert syringe (5), which has to lock into place.
• Push the filling slide (3) down a bit, and press down the stopping lever
(4) which has to lock the syringe in its place (5).
• Use the adjusting wheel (2) to set the required dosing volume.
Please observe:
• Syringe 25 ml and 50 ml should be inserted in the Minilab 201 with the
adapter (enclosed) to attach the adapter to the syringe place it on the
syringe, and fasten by turning (bayonet socket). After use of the
syringe, the adapter can be removed again and can be reused as

1. Filling the syringe
• Immerse the tip of the syringe into the liquid.
• Fil the syringe by slowly pressing the filling slide (3) upwards.
• Dispense the first dosing step.
Please observe:
• In order to prevent a negative pressure and a saturation of the liquid with minute air bubbles
when filling the syringe; the filling slide should by pushed up slowly.
• An air bubble which might be in the upper part of the cylinder will have no influence on the
accuracy if a the last dispensing step is not carried out.
• Syringe should not by filled up completely.
• Syringe 0.5 ml, 1.25 ml and 2.5 ml can be used with the yellow or transparent 200 µl pipet-
ting tips fixed filling from vessels with narrow necks is thus facilitated, and the dosing of
smaller volumes will be more precise.

• Wipe the tip of the syringe with a lint-free cellulose wadding.
• Place the tip of the syringe at an angle to the wall of the vessel.
• Press the dosing button (1) down to the stop.
