B) Automatic single liquid dispenser using disposable pipette tips
The C311 Automatic single liquid dispenser using disposable pipette tips is used to automatically
dispense a precise volume of liquid, often a drop. When combined with a automatic sample stage and
dispenser holder the Sequencer utility allows multiple drops on a sample to be measured automatically.
Figure 4.12. Automatic single liquid dispenser with disposable pipette tips .
The disposable pipette tip dispenser is to be mounted on to the liquid-dispenser holder with motorized
vertical movement. If you are upgrading from a manual precision syringe, loosen the thumbscrew on the
vertical arm of the motorized dispenser movement, lift the syringe holder assembly up from out of the
motorized vertical arm of the device and slide the pipette dispenser down into the same slot. Ensure that
the Theta is turned off for this procedure . After assembly re-tighten the thumb screw.
In the experiment tab the software will automatically provide the device controls and recipe sheet
parameters, which are the same as those for the automatic single liquid dispenser. Please see the
relevant section A above for information on their use. The C311 dispenser does not need to be
calibrated.
The tips used are disposable and easy to change.
